DEPARTMENT OF COMMERCE National Institute of Standards and Technology National Voluntary Laboratory Accreditation Program LAB BULLETIN ISSUE DATE: February 24, 2015 NUMBER: LB-85-2015 LAP: Energy Efficient Lighting LAP SUBJECT: Calibration Certificates for In-house Calibrations The purpose of this NVLAP Lab Bulletin is to clarify NVLAP s expectations with regard to calibration certificates produced by laboratories for in-house calibrations. Now that measurement uncertainty calculations are required for in-house calibration of integrating spheres, goniophotometers, and reference lamps, assessors will be looking more closely at calibration certificates produced by laboratories for their internal use. NIST Handbook 150, Annex B.3.2 allows laboratories to perform in-house calibrations provided all relevant sections of NIST Handbook 150 are met. The following sections of NIST Handbook 150 and NIST Handbook 150-1 give the requirements for a calibration certificate for in-house calibrations and the content of calibration certificates. NIST Handbook 150, NVLAP Procedures and General Requirements 5.10.4 Calibration certificates 5.10.4.1 In addition to the requirements listed in 5.10.2, calibration certificates shall include the following, where necessary for the interpretation of calibration results: a) the conditions (e.g., environmental) under which the calibrations were made that have an influence on the measurement results; b) the uncertainty of measurement and/or a statement of compliance with an identified metrological specification or clauses thereof; c) evidence that the measurements are traceable (see Note 2 in 5.6.2.1.1). 5.10.4.2 The calibration certificate shall relate only to quantities and the results of functional tests. If a statement of compliance with a specification is made, this shall identify which clauses of the specification are met or not met. When a statement of compliance with a specification is made omitting the measurement results and associated uncertainties, the laboratory shall record those results and maintain them for possible future reference. When statements of compliance are made, the uncertainty of measurement shall be taken into account. 5.10.4.3 When an instrument for calibration has been adjusted or repaired, the calibration results before and after adjustment or repair, if available, shall be reported. NVLAP LAB BULLETIN NUMBER: LB-85-2015 PAGE: 1 of 2

5.10.4.4 A calibration certificate (or calibration label) shall not contain any recommendation on the calibration interval except where this has been agreed with the customer. This requirement may be superseded by legal regulations. NIST Handbook 150-1, NVLAP Energy Efficient Lighting Products 5.6 Measurement traceability 5.6.5 The following requirements apply for calibrations and calibration certificates. b) Certificates shall be required when a laboratory performs its own calibration. If the testing laboratory performs its own calibration, the identity of the properly trained personnel involved, the standard metrological procedures used, the environmental conditions, and the measurement uncertainty shall be documented. Evidence and demonstration of traceability as required in NIST Handbook 150, Annex B, shall be documented. Records shall contain sufficient information to permit repetition of the calibration. NIST Handbook 150, 5.10.1 allows test and calibration reports for internal customers to be simplified; however, the information required by sections 5.10.2 and 5.10.4 must be available. This means that the assessor will focus on the overall record of the calibration rather than on a single, printed calibration certificate. The format of the certificate mentioned in NIST Handbook 150-1, 5.6.5 b) is not important, provided that all elements are recorded. The record may consist of any combination of paper and/or electronic documents. This bulletin should be maintained with your copy of NIST Handbook 150-1 until the next edition of the handbook is released. Questions regarding the bulletin should be directed to Timothy Rasinski, NVLAP Program Manager, at 301-975-6697, or timothy.rasinski@nist.gov. NVLAP LAB BULLETIN NUMBER: LB-85-2015 PAGE: 2 of 2

DEPARTMENT OF COMMERCE National Institute of Standards and Technology National Voluntary Laboratory Accreditation Program LAB BULLETIN ISSUE DATE: July 29, 2014 NUMBER: LB-83-2014 LAP: Energy Efficient Lighting Products SUBJECT: Addition of LM-84:2014 and CEI IEC 62471:2006 to Scopes of Accreditation The purpose of this bulletin is to publish requirements for the addition of LM-84:2014 and CEI IEC 62471:2006 to existing scopes of accreditation. Submission Requirements A laboratory seeking to add testing to its scope of accreditation must submit a completed Test Method Selection List, indicating the test methods to be added, to the Energy Efficient Lighting Products (EEL) program manager. http://www.nist.gov/nvlap/upload/eel-application.pdf Along with the list, the laboratory must submit supporting information as indicated below: IES LM-84:2014, Approved Method for Measuring Luminous Flux and Color Maintenance of LED Lamps, Light Engines, and Luminaires (22/S25): A laboratory with 22/S09 or 22/S10 or 22/S03, LM-79:2008, and 22/S18 or 22/S19, EPA Lamps v. 1.0, may have LM-84:2014 added to its scope by submitting a copy of the cover of the standard and a copy of its testing procedure. A laboratory without the above prerequisites must have an on-site assessment to have LM-84:2014 added to its scope of accreditation. CEI IEC 62471:2006, Photobiological Safety of Lamps and Lamp Systems (22/P19, 22/P20, 22/S26, 22/S27): This test method cannot be added to a scope without an on-site assessment. It can be added during a scheduled on-site assessment, or a special on-site assessment can be set up for an additional cost. 22/P19 and 22/S26 denote accreditation to test under section 5.2.1, irradiance measurements, and all supporting sections of the standard. 22/P20 and 22/S27 denote accreditation to test under section 5.2.2, radiance, and all supporting sections of the standard. All include accreditation to sections 5.2.3, measurement of source size, and 5.2.4, pulse width measurement for pulsed sources. Section 5.3.3 requires laboratories calculate and report measurement uncertainty for all results. All laboratories will be assessed to this requirement. CEI IEC 62471:2006 includes section 6 on lamp classification. NVLAP does not accredit certification bodies, i.e., ISO/IEC 17065:2012. It is improper for a laboratory accredited to perform testing as described in section 5 of the standard to classify lamps as described in section 6 as part of its accreditation. A laboratory may include this information on lamps in its test report but must indicate the classification does not fall within its NVLAP scope of accreditation as required in NIST Handbook 150, Annex A.1 h). If you have any questions, please contact the EEL program manager at timothy.rasinski@nist.gov or 301-975-6697. NVLAP LAB BULLETIN NUMBER: LB-83-2014 PAGE: 1 of 1

DEPARTMENT OF COMMERCE National Institute of Standards and Technology National Voluntary Laboratory Accreditation Program LAB BULLETIN ISSUE DATE: February 8, 2013 NUMBER: LB-72-2013 LAP: Energy Efficient Lighting Products SUBJECT: Calibration of Integrating Spheres and Goniophotometers and Associated Measurement Uncertainty The purpose of this NVLAP Lab Bulletin is to define NVLAP s expectations with regard to the calibration of integrating spheres and goniophotometers and the associated measurement uncertainty of the calibration. Measurement uncertainty requirements for testing have not changed and will continue to be assessed against the requirements of NIST Handbook 150-1, 5.4.2. The following sections of NIST Handbook 150 and NIST Handbook 150-1 are clear in the requirements that these instruments must be calibrated and when this calibration is performed in-house, the measurement uncertainty of the calibration must be determined. NIST Handbook 150, NVLAP Procedures and General Requirements 5.4 Test and calibration methods and method validation ***** 5.4.6 Estimation of uncertainty of measurement 5.4.6.1 A calibration laboratory, or a testing laboratory performing its own calibrations, shall have and shall apply a procedure to estimate the uncertainty of measurement for all calibrations and types of calibrations. 5.6 Measurement traceability 5.6.1 General All equipment used for tests and/or calibrations, including equipment for subsidiary measurements (e.g., for environmental conditions) having a significant effect on the accuracy or validity of the result of the test, calibration or sampling shall be calibrated before being put into service. The laboratory shall have an established program and procedure for the calibration of its equipment. NIST Handbook 150-1, NVLAP Energy Efficient Lighting Products 5.6 Measurement traceability 5.6.5 The following requirements apply for calibrations and calibration certificates. b) Certificates shall be required when a laboratory performs its own calibration. If the testing laboratory performs its own calibration, the identity of the properly trained personnel involved, the standard metrological procedures used, the environmental conditions, and the measurement uncertainty shall be documented. Evidence and demonstration of traceability as required in NIST Handbook 150, Annex B, shall be documented. Records shall contain sufficient information to permit repetition of the calibration. NVLAP LAB BULLETIN NUMBER: LB-72-2013 PAGE: 1 of 2

There are not many calibration laboratories that offer the calibration of integrating spheres and goniophotometers, and testing laboratories commonly perform this calibration in-house with the use of a reference standard lamp traceable through an NMI (national metrology institute). There are two important points concerning the measurement uncertainty of the calibration: 1) the uncertainty of the calibration of a piece of equipment includes more than the uncertainty of the reference standard used to calibrate the equipment, and 2) the uncertainty of the calibration of a piece of equipment is not the same as the uncertainty associated with using that piece of equipment to make a test measurement. NVLAP has not consistently reviewed calibration records for integrating spheres and goniophotometers in the past, especially for measurement uncertainty requirements. Also, we understand that there is not a lot of guidance and training available for lighting testing and calibration measurement uncertainty. Considering this, for the next two years NVLAP assessors will ask to review calibration records for integrating spheres and goniophotometers. These records may be from an accredited calibration laboratory per Annex B.3.3 of NIST Handbook 150, or the calibration may be performed in-house per Annex B.3.2. If the laboratory is not able to supply these records with the associated measurement uncertainty, the assessor will document a comment in the assessment report. After December 31, 2014, assessors will write nonconformities for laboratories that do not meet the requirements. NVLAP is exploring options to provide training in measurement uncertainty and will make future announcements as more is known. This bulletin should be maintained with your copy of NIST Handbook 150-1 until the next edition of the handbook is released. Questions regarding the bulletin should be directed to Timothy Rasinski, NVLAP Program Manager, at 301-975-6697, or timothy.rasinski@nist.gov. NVLAP LAB BULLETIN NUMBER: LB-72-2013 PAGE: 2 of 2

DEPARTMENT OF COMMERCE National Institute of Standards and Technology National Voluntary Laboratory Accreditation Program ISSUE DATE: July 19, 2012 LAB BULLETIN NUMBER: LB-67-2012 LAP: Energy Efficient Lighting (EEL) SUBJECT: Addition of In-Situ Temperature Method (ISTM) Testing to EEL Program The NVLAP Energy Efficient Lighting Products program is now accrediting in-situ temperature method (ISTM) testing. This is in support of the ENERGY STAR Program Requirements Product Specifications for Luminaires (Light Fixtures) Version 1.1. The purpose of this accreditation is to support lumen and color maintenance testing only. This accreditation does not cover product safety testing. The following test methods have been added to the Test Method Selection List: 22/S15 ANSI/UL 153:2002 (Secs. 124-128A) Standard for Portable Electric Luminaires 22/S16 ANSI/UL 1574:2004 (Sec. 54) Standard for Track Lighting Systems 22/S17 ANSI/UL 1598:2008 (Secs. 19.7, 19.10-16) Luminaires These are the revision dates specified in the ENERGY STAR document. Accreditation is limited to the specified sections. Accreditation to these test methods does not imply acceptance by specifiers (e.g., EPA, DOE). Please contact your customers to see if testing to these standards will be accepted. Questions should be directed to Timothy Rasinski at 301-975-6697, or <timothy.rasinski@nist.gov>.

DEPARTMENT OF COMMERCE National Institute of Standards and Technology National Voluntary Laboratory Accreditation Program ISSUE DATE: August 9, 2011 LAB BULLETIN NUMBER: LB-60-2011 LAP: Energy Efficient Lighting (EEL) SUBJECT: Update of Energy Efficient Lighting Test Method Selection List Effective August 4, 2011, the Energy Efficient Lighting LAP released a revised Test Method Selection List. The list now includes IES TM-21:2011 (22/S12). The test method has been approved for publication and is expected to be published in the fall of 2011. Labs currently accredited to IES LM-80 may have this test method added to the scope of accreditation through a document review. Labs must have a copy of the standard, so NVLAP cannot start the process until the standard is formally published. Labs not accredited to IES LM-80 must have an on-site assessment to have IES LM-80 added, as well as IES TM-21. The 22/DXX series of standards have been added for accreditation for decorative light strings testing. Please note that accreditation to ASTM G154 is a requirement. IES LM-82:20XX draft (22/S13) has been added. NVLAP will not accredit to standards under development. This method has been placed on the selection list to help NVLAP and assessors plan for upcoming assessments. In some cases, an assessor may be able to perform a preliminary review of a draft test method to aid in adding it to the scope of accreditation when finalized. This review will be performed at the discretion of NVLAP and the assessor. If the test method is finalized before the assessment, the assessor will review the test method for addition to the scope of accreditation during the assessment. The proficiency testing indicated for this test method will be administered by NIST at some future date in a method similar to LM-79 testing. Participation in proficiency testing prior to accreditation is not required. ANSI C78.376 (22/E28), ANSI C82.11 (22/E29), and ANSI C78.377 (22/S11) have been removed from the selection list. These were added earlier in the year when EPA added them to its list of required standards. These methods were removed in the June release of required standards (http://www.energystar.gov/ia/partners/downloads/mou/guide_to_epa_lab_recognition_by_lighti ng_category.pdf). The reasoning behind the removal is these are not test methods; they are specifications and more appropriate for certification bodies. These standards will be removed from existing scopes in the near future and the scopes reissued. Prior to adding these earlier this year, NVLAP had not had any requests for accreditation to these standards. If any specifier requests accreditation to these standards, please contact NVLAP. Questions concerning the revised selection list should be directed to Timothy Rasinski at 301-975-6697, or <timothy.rasinski@nist.gov>. NVLAP LAB BULLETIN NUMBER: LB-60-2011 PAGE: 1 of 1

Foreword The NIST Handbook 150 publication series sets forth the procedures, requirements, and guidance for the accreditation of testing and calibration laboratories by the National Voluntary Laboratory Accreditation Program (NVLAP). The series is comprised of the following publications: NIST Handbook 150, NVLAP Procedures and General Requirements, which contains the general procedures and requirements under which NVLAP operates as an unbiased third-party accreditation body; NIST Handbook 150-xx program-specific handbooks, which supplement NIST Handbook 150 by providing additional requirements, guidance, and interpretive information applicable to specific NVLAP laboratory accreditation programs (LAPs). The program-specific handbooks are not stand-alone documents, but rather are companion documents to NIST Handbook 150. They tailor the general criteria found in NIST Handbook 150 to the specific tests, calibrations, or types of tests or calibrations covered by a LAP. NIST Handbook 150-1, NVLAP Energy Efficient Lighting Products, presents the technical requirements and guidance for the accreditation of laboratories under the NVLAP Energy Efficient Lighting Products LAP. The 2010 edition incorporates the requirements of NIST Handbook 150-1A, NVLAP Energy Efficient Lighting Products Solid State Lighting, which was released in 2009 as a separate handbook. These two handbooks have been combined to reduce the number of documents used by the EEL Program and to eliminate redundancies. The new edition of NIST Handbook 150-1 supersedes and replaces both the 2008 edition of NIST Handbook 150-1 and the 2009 edition of NIST Handbook 150-1A. The handbook was revised with the participation of technical experts in the field of energy efficient lighting products testing and was approved by NVLAP. In addition to incorporating the requirements of NIST Handbook 150-1A, the following changes have been made to this handbook with respect to the previous edition: all references to applicable guides and standards have been updated; updated federal regulations and information on the voluntary ENERGY STAR program have been included. This handbook is also available on the NVLAP web site (http://www.nist.gov/nvlap). Questions or comments concerning this handbook should be submitted to NVLAP, National Institute of Standards and Technology, 100 Bureau Drive, Stop 2140, Gaithersburg, MD, 20899-2140; phone: 301-975-4016; fax: 301-926-2884; e-mail: nvlap@nist.gov. iv NIST Handbook 150-1:2010

Introduction Background As part of broader energy conservation issues, the Energy Policy and Conservation Act (Public Law 94-163) was passed in 1975 in response to the oil crisis of the early 1970s. It has been amended several times, most notably in 1992 by the Energy Policy Act (EPAct) (Public Law 102-486). The Energy Policy Act of 1992 requires that the U.S. Department of Energy specify energy efficiency standards for certain types of fluorescent and incandescent reflector lamps. 1 New efficiency standards created by the Energy Policy Act of 2005 (EPAct 2005) (Public Law 109-58) were signed into law on August 8, 2005, and went into effect on January 1, 2006. In the case of luminaires, Public Law 102-486 does not require that the Department of Energy set mandatory energy efficiency standards. Rather, it mandates that the Department of Energy assist industry in developing a voluntary national program that informs consumers of the energy savings to be achieved in selecting certain types of luminaires. Elements of the voluntary program include the selection of the types of luminaires, the specifying of test procedures, and the development of a consumer information system. In this case, the Department of Energy is required to monitor the voluntary program and determine whether it is sufficient to meet the objectives of the Energy Policy Act of 1992. Development of laboratory accreditation program On November 27, 1990, the Lighting Equipment Division of the National Electrical Manufacturers Association (NEMA) requested that the National Voluntary Laboratory Accreditation Program (NVLAP), which is the Laboratory Accreditation Group within the National Institute of Standards and Technology (NIST), establish an accreditation program for laboratories that test certain types of lamps and luminaires. The purpose of the program was to accredit testing laboratories to assure that standard test methods for product performance (excluding product safety) are followed in testing electric lighting products (10CFR430.25). The announcement of the development of the NVLAP Energy Efficient Lighting Products (EEL) laboratory accreditation program (LAP) was published in the Federal Register on May 15, 1991. In 2008 NVLAP updated NIST Handbook 150-1 to include new requirements set forth in EPAct 2005, including the test methods cited in the ENERGY STAR program. EPAct 2005 formally recognizes the federal ENERGY STAR program (Section 131 of the Energy Policy Act, Public Law 109-58) to identify and promote energy-efficient products and buildings through labeling. As written in Section 131: There is established within the U.S. Department of Energy and the U.S. Environmental Protection Agency a voluntary program to identify and promote energy-efficient products and buildings in order to reduce energy consumption, improve energy security, and reduce pollution through voluntary labeling of, or other forms of communication about, products and buildings that meet the highest energy conservation standards. Section 131 calls for enhancing public awareness of ENERGY STAR, preserving the integrity of the label, regularly updating performance criteria, soliciting comments from interested parties, and providing appropriate lead time when changes are being made to program criteria. Lighting products currently covered by the ENERGY STAR program include exit signs, residential lighting fixtures, residential ceiling fans, ventilating fans, and medium-screw base compact fluorescent lamps (CFLs). 1 Refer to Code of Federal Regulations, Title 10 Energy, Part 430 Energy Conservation Program for Consumer Products (10 CFR Part 430) and Title 42 U.S. Code 6291-6295 for the energy efficiency standards and related test procedures. NIST Handbook 150-1:2010 v

As part of the ENERGY STAR program for solid state lighting, the Department of Energy requested that NVLAP add to the NVLAP EEL LAP specific test methods used in testing certain types of solid state lighting products and LED sources. The purpose of this addition of test methods is to accredit testing laboratories to ensure that standard test methods for product performance (excluding product safety) are followed in testing solid state lighting products and LED sources. NIST Handbook 150-1A initially presented the technical requirements and guidance for the accreditation of laboratories for testing solid state lighting products and LED sources. Those requirements have been incorporated into NIST Handbook 150-1 to minimize the number of documents, since many of the requirements are similar. vi NIST Handbook 150-1:2010

1 General information 1.1 Scope of handbook 1.1.1 NIST Handbook 150-1 specifies the technical requirements and provides guidance for the accreditation of laboratories under the NVLAP Energy Efficient Lighting Products Laboratory Accreditation Program (EEL Program). It supplements the NVLAP procedures and general requirements found in NIST Handbook 150, NVLAP Procedures and General Requirements, by tailoring the general criteria found in NIST Handbook 150 to the specific tests and types of tests covered by the EEL Program. 1.1.2 NIST Handbook 150, NIST Handbook 150-1, and their respective checklists (see 1.6) constitute the collective body of requirements that must be met by a laboratory seeking NVLAP accreditation to specific test methods for the EEL Program. 1.1.3 This handbook is intended for information and use by accredited EEL laboratories, assessors conducting on-site assessments, laboratories seeking accreditation, other laboratory accreditation systems, users of laboratory services, and others needing information on the requirements for accreditation under the EEL Program. 1.2 Organization of handbook The numbering and titles of the first five clauses of this handbook match those of NIST Handbook 150. The primary subclauses in clauses 4 and 5 (e.g., 4.1, 4.2, etc.) are also numbered and titled to correspond with the subclauses in NIST Handbook 150, even when there are no requirements additional to those in NIST Handbook 150. 1.3 Program description 1.3.1 The NVLAP EEL Program provides for laboratory accreditation to ensure that standard test procedures are followed to measure electrical, photometric, colorimetric, and life-performance characteristics of incandescent, fluorescent and high intensity discharge lamps, to measure the photometric characteristics of luminaries (lighting fixtures) using the above-named sources, and to measure electrical, photometric, colorimetric, and lumen maintenance characteristics of solid state lighting products and LED sources. 1.3.2 The EEL Program accredits laboratories through the use of test methods or procedures developed by the Illuminating Engineering Society (IES), standards entitled ANSI (American National Standards Institute), and procedures developed by the Commission Internationale de l Eclairage (CIE). 1.3.3 A listing of the test methods included in the NVLAP program is given in the EEL Test Method Selection List, which is part of the EEL application package and available from NVLAP upon request. The Test Method Selection List is grouped into tests for lamps, luminaires (lighting fixtures), and solid state lighting. A laboratory may seek accreditation to all of the selected methods offered in the EEL Program or a subset of its choice. A laboratory may request that test methods be added to the program. Test method additions will be handled in accordance with NVLAP procedures in NIST Handbook 150 for adding to or modifying an established laboratory accreditation program (LAP) (see NIST Handbook 150, clause 2).

The LED luminaire is intended to connect directly to a branch circuit. 1.5.4 luminaire (light fixture) A complete lighting unit consisting of a lamp(s) and ballast(s) (when applicable) together with the parts designed to distribute the light, to position and protect the lamps, and to connect the lamps to the power supply. 1.6 Program documentation 1.6.1 General Assessors use NVLAP checklists to ensure that each laboratory receives an assessment comparable to that received by others and to assure completeness, uniformity, and objectivity. Checklists assist assessors in documenting the assessment to the NVLAP requirements found in NIST Handbook 150, this handbook, and the checklists themselves. Checklists contain definitive statements or questions about all aspects of the NVLAP requirements for accreditation and form part of the On-Site Assessment Report (see NIST Handbook 150). The current version of each checklist is available from the NVLAP web site at <http://www.nist.gov/nvlap>. 1.6.2 NIST Handbook 150 Checklist All NVLAP programs use the NIST Handbook 150 Checklist (formerly called the General Operations Checklist), which contains the requirements published in NIST Handbook 150. The checklist items are numbered to correspond to clauses 4 and 5 and annexes A and B of NIST Handbook 150. 1.6.3 NIST Handbook 150-1 Checklist The NIST Handbook 150-1 Checklist (also referred to as the EEL Program-Specific Checklist) addresses the requirements specific to Energy Efficient Lighting Product testing given in NIST Handbook 150-1 with an emphasis on observing and performing tests, testing accuracy and uncertainty, traceability chain and associated calibration uncertainty of standard reference lamps and standard photometers, instrumentation, calibration, personnel competency, and test reporting. The checklist contains requirements expressed at a more detailed level than found in this handbook. 1.6.4 Test Method Review Summary The assessor uses the Test Method Review Summary to review the laboratory s ability to perform the EEL test methods. The review of the test methods by the assessor ranges from observing tests to having laboratory staff describe the test procedures. The assessor notes on the Test Method Review Summary the depth into which each part of the test method was reviewed (Observed Test, Walked/Talked Through Test, Listened to Description of Procedures, Examined Apparatus). NIST Handbook 150-1:2010 3

1.6.5 NVLAP Lab Bulletins NVLAP Lab Bulletins are issued to laboratories and assessors when needed, to clarify program-specific requirements and to provide information about program additions and changes. NVLAP Lab Bulletins dealing with the EEL Program are available on the NVLAP website, <http://www.nist.gov/nvlap>. 2 LAP establishment, development and implementation This clause contains no information additional to that provided in NIST Handbook 150, clause 2. 3 Accreditation process 3.1 General An overview of the laboratory accreditation process is provided in NIST Handbook 150, clause 3, and includes information pertaining to application for accreditation; on-site assessment; proficiency testing; accreditation decision; granting accreditation; renewal of accreditation; changes to scope of accreditation; monitoring visits; and suspension, denial, revocation, and voluntary termination of accreditation. 3.2 Management system review 3.2.1 Prior to applying to NVLAP for accreditation, a laboratory shall have a fully implemented management system. A copy of the management system documentation shall be sent to NVLAP with the application forms. If the documentation does not follow the numbering system of NIST Handbook 150, a cross-reference document shall also be sent to NVLAP. The requirement for a cross-reference document applies to both applicant laboratories and laboratories already accredited by NVLAP (see 4.2.1). 3.2.2 Prior to the on-site assessment, the assigned assessor reviews all relevant management system documentation for conformity with NVLAP requirements, including the requirements of this handbook and NIST Handbook 150. During this review, the assessor may request additional management system and/or technical documents and/or records, which will be returned upon request. 3.3 On-site assessment 3.3.1 The purpose of the on-site assessment is to determine whether the laboratory is following its documented management system and to assess the competence of the laboratory s delivery of its testing services. 3.3.2 The on-site assessment will take place at the laboratory site. Prior to the visit, the NVLAP assessor provides a preliminary agenda, which may change due to findings observed during the on-site assessment. Efforts will be made to minimize disruption to the normal working routines during the assessment. The assessor will need time and workspace to complete assessment documentation during his/her time at the laboratory site. 4 NIST Handbook 150-1:2010

3.3.3 All laboratory equipment required to perform accredited testing shall be available for assessment and in good working order. Although all test methods need not be set up and operational during the onsite assessment, the laboratory shall be prepared to demonstrate selected test methods as requested by the assessor. For those cases where the test methods are not operational and a demonstration is not requested, the laboratory shall be prepared to describe the test method and procedures it would follow and show the actual equipment, fixtures and arrangements that would be used. The assessment will cover the requirements identified in this handbook, NIST Handbook 150, the laboratory s management system documentation, and the laboratory s written detailed test instructions. 3.3.4 The laboratory shall make available all supporting technical information in a format that is conducive to a detailed review. The assessor may request additional information to clarify issues regarding nonconformities or to delve more deeply into technical issues. 3.3.5 The activities covered during a typical on-site assessment are described below. a) Opening meeting: The NVLAP assessor will meet with laboratory management, supervisory personnel, and other appropriate staff members to explain the purpose of the on-site assessment and to discuss the schedule for the assessment activities. Information provided by the laboratory on its application form may be discussed during this meeting. b) Staff interviews: The assessor will ask the laboratory manager to assist in arranging times for individual interviews with laboratory staff members. The assessor will interview staff members filling key positions (e.g., Laboratory Manager, Technical Director, Quality Manager, Authorized Representative, Approved Signatories) and staff members who have an effect on the outcome of the testing, including staff who conduct the testing. The assessor does not need to talk to all staff members; however, the assessor will select staff members representing all aspects of the laboratory. These interviews are conducted to determine if the staff members are properly trained, assigned, and supervised, and are technically competent for the tasks assigned to them. c) Records review: The assessor will review laboratory documentation, including the management system documentation, equipment and maintenance records, record-keeping procedures, testing procedures, laboratory test records and reports, personnel competency records, personnel training plans and records, and safeguards for the protection of sensitive and proprietary information. The assessor will review the laboratory s own detailed instructions (see 5.4.1) to perform EEL testing according to the standard test procedures for which the laboratory is accredited (or is seeking accreditation), the range of energy efficient lighting products and conditions it can test, and the descriptions of the maintenance and calibration of its specific equipment. The assessor will also review: 1) sample identification and tracking procedures and copies of completed test reports; 2) records of internal audits, use of quality control procedures, and participation in NVLAP proficiency testing or other similar programs; 3) personnel records, including résumés and job descriptions of key personnel and competency evaluations for all staff members who routinely perform the test method for which accreditation is sought; 4) calibration records and certificates (see 5.6.5); 5) records of evaluations, verifications and testing of purchased services, equipment, etc. NIST Handbook 150-1:2010 5

Laboratory staff shall be available to answer questions pertaining to the accreditation review; however, the assessor may wish to review the documents and records alone. The assessor usually does not ask to remove any laboratory documents or records from the laboratory premises. d) Internal audit and management review: The assessor will review and discuss with the laboratory staff the laboratory s internal audit and management review activities, which are separate and distinct activities. The discussion will include all aspects of those activities including management system procedures, audit findings, root cause determination, actions taken to resolve problems identified, actions taken to prevent recurrence, and results of the management review. e) Equipment and software: The assessor will examine and determine the suitability of all equipment and facilities required to perform the standard test methods for which the laboratory is accredited (or is seeking accreditation). The appropriate environmental conditions required for testing will be assessed. The assessor will observe the demonstration of selected procedures by appropriate personnel assigned to conduct the tests, and will interview those personnel. The assessor will review test data, examine hardware and software for function and appropriateness, and review software validation and verification procedures. f) Demonstrations: Demonstrations requested may be selective or all-inclusive. The assessor will observe the demonstration of testing procedures by technical personnel assigned to conduct the tests, and will discuss the tests with the technical personnel to assure their understanding of the procedures. Demonstrations shall include sample energy efficient lighting product(s), preparation of devices, establishment of test conditions, and setup/use of major equipment. The assessor will use the Test Method Review Summary (see 1.6.4) and the EEL Program-Specific Checklist (see 1.6.3) in reviewing and summarizing the laboratory s ability to conduct the test methods. The assessor may select and trace the history of one or more energy efficient lighting product samples from receipt to final issuance of the test reports. g) Proficiency testing: The assessor will discuss all aspects of proficiency testing results with appropriate staff. Test methodology and records documenting the laboratory s execution of testing will be reviewed and discussed. Any unusual trends or outlying results will be discussed. The assessor may provide an energy efficient lighting product(s) as a proficiency test specimen and request testing or a demonstration. h) On-site assessment report: The assessor will complete an On-Site Assessment Report, which summarizes findings and clearly lists all nonconformities and comments (positive or negative). This report normally consists of the On-Site Assessment Narrative Summary, the NIST Handbook 150 Checklist, the EEL Program-Specific Checklist, and the Test Method Review Summary. The first page of the report shall be signed by the assessor and the laboratory s Authorized Representative or designee to acknowledge receiving the on-site report, but signing the report does not necessarily indicate agreement by the laboratory. A copy of the report will be given to the laboratory representative for retention and the assessor will send the original to NVLAP. All observations made by the assessor will be held in confidence as stated in the declaration signed by all assessors and NVLAP staff. i) Closing meeting: The assessor will conduct a closing meeting with the laboratory manager, supervisory personnel, and other appropriate staff members to discuss the findings. During the visit the assessor will have categorized all problems identified as nonconformities and comments. 6 NIST Handbook 150-1:2010

They will be discussed at the closing meeting and resolutions may be mutually agreed upon. The assessor will specifically note items that have been corrected during the on-site assessment along with any recommendations for other action(s). The process for resolving nonconformities identified during the on-site is documented in NIST Handbook 150. Disagreements between the laboratory and the assessor shall be referred to NVLAP for resolution. 3.3.6 The laboratory shall review all comments for potential improvements in energy efficient lighting product testing. 3.4 Proficiency testing 3.4.1 NIST Handbook 150 defines proficiency testing and describes how it is included in the accreditation process. EEL test methods that require proficiency testing are identified by an asterisk (*) in the EEL Test Method Selection List. Special proficiency testing rounds may be scheduled separately for specific needs. Proficiency testing fees are required from all laboratories accredited for one or more test methods for which proficiency testing is being offered. 3.4.2 Laboratories applying for initial accreditation for solid state test methods shall participate satisfactorily in bilateral proficiency testing with NIST before accreditation is granted. Solid state lighting products and LED sources along with instructions for specimen handling, preparation (including seasoning and pre-burning), conditioning, mounting, and testing, and data forms are provided to the participating laboratory. The completed test data forms are sent by the participating laboratory to NIST. The results are summarized in a report, which is sent by NVLAP to the participant. 3.4.3 Laboratories applying for initial accreditation for test methods that do not include solid state test methods may be required to participate satisfactorily in proficiency testing of compact fluorescent and/or incandescent lamps before accreditation is granted. Lamps along with instructions for specimen handling, preparation (including seasoning and pre-burning), conditioning, mounting, and testing, and data forms are provided to the participating laboratory. The completed test data forms are sent by the participating laboratory to NVLAP. The results are summarized in a report, which is sent by NVLAP to the participant. 3.4.4 As NVLAP prescribes, NVLAP or a proficiency testing contractor conducts rounds at regular intervals. The completed test data forms are sent by the participating laboratory to NVLAP and, if directed, to the proficiency testing contractor. The results of all participants are summarized in a Tech Brief, which is published and sent by NVLAP to the participants. The identity and performance of individual laboratories are kept confidential. 3.4.5 Laboratories renewing accreditation shall have satisfactorily participated in all required proficiency testing during their previous accreditation period. Failure to participate in proficiency testing or to return the completed test data forms by the deadline is considered a nonconformity and may result in suspension of laboratory accreditation for those test methods in question. 3.4.6 Generally, it is required that the specific proficiency test procedure be conducted in accordance with the applicable standard test method. At times, however, NVLAP may specify special conditions to assure uniformity in procedures and test conditions among participants. These may include the number of replicate measurements, special conditions of temperature, and other test parameters. Also, proficiency testing may consist of several parts in order that the operation of a laboratory might be evaluated. Portions of the standard test procedure may be emphasized, such as measurement, instrumentation, hardware, and data analysis. The proficiency testing shall not be contracted out to another laboratory. NIST Handbook 150-1:2010 7

3.4.7 In no case shall proficiency test samples be considered as calibration standards or standard reference materials or be used as substitutes for calibration standards that are traceable to NIST or other national metrology institutes (NMIs). 3.4.8 Under the direction of NVLAP or the proficiency testing contractor, proficiency test samples may be temporarily detained (e.g., for retesting) at a laboratory. Also, on occasion, the on-site assessor hand carries proficiency test samples to the laboratory. All proficiency test samples, like all other samples received by the laboratory, shall be listed or entered into the normal sample tracking and identification system for control and data recording. NVLAP or the proficiency testing contractor will direct the laboratory to send the proficiency test samples to a specified destination (e.g., next laboratory, proficiency testing contractor, NVLAP, or the on-site assessor). 3.4.9 Proficiency test data are analyzed by NVLAP and/or a proficiency testing contractor using statistical procedures to determine distributions and parameters, such as averages, standard deviations, and outliers (see ASTM E178). Using the test data from proficiency testing, the laboratory shall monitor its own testing performance. Procedures for analyzing and monitoring the laboratory s own test results shall be documented in its management system. 3.4.10 Unsatisfactory performance in proficiency testing (e.g., outlying results) as determined by NVLAP is a technical nonconformity that shall be resolved by the laboratory to maintain its accreditation for the test method(s) in question. If the laboratory performs unsatisfactorily in any proficiency test, it shall take corrective action to investigate and resolve nonconformities in a timely manner, according to the requirements in 4.9 of NIST Handbook 150 for the control of nonconforming work. Unsatisfactory performance in proficiency testing may result in suspension or revocation of accreditation. 3.4.11 The results of proficiency testing shall be made available to NVLAP assessors for use during laboratory on-site assessment visits. Any problems indicated by proficiency testing shall be discussed with appropriate laboratory personnel responsible for developing and implementing plans for resolving the problems. 4 Management requirements for accreditation 4.1 Organization There are no requirements additional to those set forth in NIST Handbook 150. 4.2 Management system 4.2.1 The laboratory shall create a cross-reference document that facilitates verification by both the laboratory and the NVLAP assessor that all program requirements have been addressed by the management system. This review includes clauses 4 and 5 and annexes A and B of NIST Handbook 150 and the corresponding NIST Handbook 150-1. The cross-reference document requirement can be satisfied in a number of ways. One way is to number and organize the management system documentation using the same scheme shown the NIST Handbook 150 Checklist; however, other methods may be acceptable. 8 NIST Handbook 150-1:2010

These records shall be kept for a period of at least three years following the issuance of a test report, unless a longer period is required by the customer, regulation, or the laboratory s own procedures. 4.14 Internal audits 4.14.1 The internal audit shall cover compliance with NVLAP, laboratory management system, contractual, testing, and test method requirements and shall be completed at an interval no greater than two years. A NVLAP on-site assessment does not take the place of an internal audit. 4.14.2 An applicant laboratory shall conduct at least one complete internal audit, including the test methods that are requested to be on the laboratory s scope of accreditation, prior to the first on-site assessment. The internal audit report and pertinent records will be reviewed by the NVLAP assessor before or during the on-site assessment. 4.14.3 For accredited laboratories, reports and pertinent records for internal audits conducted since the previous on-site assessment shall be made available for review during the on-site assessment. 4.15 Management reviews 4.15.1 Periodic reviews of the management system shall reflect adherence to NVLAP requirements and the laboratory s quality objectives and shall be completed, at a minimum, on an annual basis. 10 NIST Handbook 150-1:2010

4.15.2 An applicant laboratory shall perform at least one complete management review prior to the first on-site assessment. The management review report(s) and pertinent records will be reviewed by the NVLAP assessor before or during the on-site assessment. 4.15.3 For accredited laboratories, reports and pertinent records for management reviews conducted since the previous on-site assessment shall be made available for review during the on-site assessment. 5 Technical requirements for accreditation 5.1 General There are no requirements additional to those set forth in NIST Handbook 150. 5.2 Personnel 5.2.1 Personnel records 5.2.1.1 Key NVLAP accreditation personnel The laboratory shall maintain a document of personnel designated to fulfill NVLAP requirements including: Laboratory Director, Technical Director, Team Leaders, NVLAP Authorized Representative, NVLAP Approved Signatories, and the staff responsible for conducting testing. This document shall be reviewed by the assessor at the on-site assessment. 5.2.1.2 All testing laboratory staff The laboratory shall document and maintain records on the required qualifications of each staff member, including a résumé of qualifications; laboratory testing procedures to which the person is assigned and authorized to perform; and the results of periodic testing performance (competency) reviews (see also 5.2.3.4), which may include interlaboratory testing and/or repeated testing by the same operator or comparative testing with two or more operators. 5.2.1.3 Notification of changes The laboratory shall notify NVLAP when key personnel (see 5.2.1.1) are added to or removed from the staff. Notification to NVLAP of personnel changes shall include a current résumé for each new staff member. 5.2.2 Specific experience and competence of Technical Director The laboratory s Technical Director (or an appropriate supervisor) shall have a combination of knowledge, experience and training in testing energy efficient lighting products under the scope of the test methods selected by the laboratory and shall have the technical competence and the supervisory capability to direct the work of professionals and technicians in testing energy efficient lighting products. 5.2.3 Competency reviews 5.2.3.1 The laboratory shall develop an appropriate list of staff member competencies for each test method. Competencies may include specimen preparation and/or mounting techniques; techniques for measuring ambient thermal conditions; lamp seasoning and stabilization procedures; procedures for transporting lamps between warm-up racks and measurement apparatus; voltage, current, and electrical power measurements; oscilloscope measurements; ballast circuit connection and verification; photometric NIST Handbook 150-1:2010 11

calibration techniques; thermocouple mounting and calibration; colorimetric measurement techniques; and goniophotometric measurement techniques among many possible techniques. 5.2.3.2 The laboratory shall evaluate the competency of each staff member for each test method or part of a test method the staff member is authorized to conduct. 5.2.3.3 For each staff member, the staff member s immediate supervisor, or a designee appointed by the Laboratory Director, shall conduct annually an assessment and/or an observation of performance competency. 5.2.3.4 These annual performance competency reviews shall be documented, dated, signed by the supervisor and the employee, retained in the personnel files and be available for review by the assessor. For the purpose of on-site assessments, a separate personnel folder of information specific to applicable NVLAP requirements may be provided instead of the complete folder, which may contain confidential information not needed for the assessment. 5.2.4 Training The training program shall be maintained and updated. Current staff members shall be given additional training when accredited test methods are updated or procedures change, or when the individuals are assigned new responsibilities. NOTE Each staff member may receive training for assigned duties either through on-the-job training, formal classroom study, attendance at conferences, or other appropriate mechanisms. 5.3 Accommodation and environmental conditions 5.3.1 Monitoring devices shall be calibrated (if required see 5.6.1 and 5.6.2.2.1 and their notes in NIST Handbook 150) and functioning properly so as to maintain and record the environmental conditions required (a) by the standards or laboratory methods or (b) where the environmental conditions influence the quality of the test results. 5.3.2 The laboratory shall maintain and document the required environmental conditions as specified in the particular standard test procedure/method to which the laboratory is accredited. The environmental conditions include: a) temperature; b) relative humidity; c) air movement; d) ambient lighting. 12 NIST Handbook 150-1:2010

5.4 Test and calibration methods and method validation 5.4.1 Standard test methods 5.4.1.1 The management system documentation shall contain or make reference to detailed written documentation of the procedures, practices, instructions and equipment that the laboratory uses in conducting the test methods for the different types of lamps, luminaires, solid state lighting products or LED devices for which it seeks or holds accreditation. These detailed instructions, including those for equipment operation, calibration checks, quality control checks, and operation of particular type(s) of devices tested shall address any laboratory-specific information not contained in the standard method and shall be supplemented with additional detailed instructions beyond the test method to ensure consistent application. Simply referencing the IES LM or ANSI standard is not acceptable. 5.4.1.2 All energy efficient lighting devices shall be tested in the orientation specified by the standard or by the customer. 5.4.1.3 All energy efficient lighting devices shall be properly seasoned or preburned according to the standard or specified by the customer. 5.4.1.4 Measurements of energy efficient lighting products shall only be reported after test units have stabilized. 5.4.1.5 For lumen performance tests, laboratory procedures for monitoring and recording lumen maintenance times along with specimen failure shall be appropriate to the test methods. NOTE For lumen maintenance tests, a laboratory should develop procedures and methods to account for changes in its measurement system that will affect the reproducibility of the measurement system over the duration of the lumen maintenance test. 5.4.1.6 Self-absorption correction procedures shall be applied for sphere measurements, or documented evidence shall be collected demonstrating that self-absorption correction is not required. 5.4.1.7 Adjustments for instrument electrical losses, if any, shall be applied. 5.4.1.8 The Illuminating Engineering Society (IES) LM-58 (NVLAP Code 22/C01 or 22/S01), Spectroradiometric Measurements, prescribes in general terms the instrument and measurement requirements, calibration procedures, and physical standards for conducting the measurements, but is not specific as to instrument, object, or material. A laboratory seeking or holding accreditation for colorimetric measurements of light sources conducted in accordance with IES LM-58 shall include, in the management system documentation, detailed laboratory-specific (see 5.4.1.1) descriptions of the procedures it uses to conduct testing in compliance with LM-58. 5.4.1.9 The Commission Internationale de l Eclairage (CIE) Pub. 13.2:1974 (NVLAP Code 22/C03) Method of Measuring and Specifying Color Rendering of Light Sources or, CIE Pub. 13.3:1995 (NVLAP Code 22/C04 or 22/S02) Method of Measuring and Specifying Color Rendering of Light Sources prescribes in general terms the method for conducting the measurements and the calculation required to determine the color rendering index. A laboratory seeking or holding accreditation for colorimetric measurements of light sources conducted in accordance with CIE Pub. 13.2:1974 and/or CIE Pub. 13.3:1995 shall include, in the management system documentation, detailed laboratory-specific (see 5.4.1.1) descriptions of the procedures it uses to conduct testing. In addition, the laboratory shall provide NIST Handbook 150-1:2010 13

documentation validating the calculation procedure used to determine the color rendering index. Commercially obtained software provided by the instrumentation manufacturer need not be validated. 5.4.1.10 The Commission Internationale de l Eclairage (CIE) Pub. 15:2004 (NVLAP Code 22/S05) Colorimetry prescribes in general terms the method for conducting the measurements and the calculation required to determine the correlated color temperature and chromaticity coordinates among other quantities. A laboratory seeking or holding accreditation for colorimetric measurements of light sources conducted in accordance with CIE Pub. 15:2004 shall include, in the management system documentation, detailed laboratory-specific (see 5.4.1.1) descriptions of the procedures it uses to conduct testing. In addition, the laboratory shall provide documentation validating the calculation procedures used to determine the color quantities described in this technical recommendation. Commercially obtained software provided by the instrumentation manufacturer need not be validated. 5.4.2 Estimation of measurement uncertainty The management system documentation shall list the important components that substantially affect the uncertainty of the test results for each test method. This can be done for groups of similar test methods (e.g., grouped by electrical, photometric [intensity, flux], colorimetric, life-performance properties, or lumen maintenance) rather than for each test method. Further, an estimate of the uncertainty contribution of the important components shall be quantified. The uncertainty shall be determined in more detail and reported if required by the test method, the regulator, or the customer. NOTE The uncertainty contribution of the important components only need be approximated. At this time documentation validating the uncertainty contribution is not required. 5.5 Equipment 5.5.1 The laboratory shall notify NVLAP when key testing equipment is added, removed, or altered. Documentation of equipment performance validation shall be provided to NVLAP. 5.5.2 The laboratory shall ensure that test equipment, devices, and instruments meet the required accuracy regulations and calibration conditions for the appropriate documentary standard specifications. 5.5.3 The laboratory shall ensure that electrical power is conditioned and regulated as required by the appropriate documentary standard specifications. 5.5.4 Standard reference lamps shall be recalibrated at appropriate intervals determined by the laboratory. NOTE Typical reference lamps decrease in luminous intensity by 0.6 % every 24 hours of burning time when operated at a current that produces a correlated color temperature of 2856 K. An acceptable calibration interval for a standard reference lamp would be 30 hours to 50 hours of burning time. 5.5.5 The laboratory shall maintain a record or log of the number of hours each reference lamp is burned. 5.6 Measurement traceability 5.6.1 Measurement traceability is a property of the measurement result. Traceability is established to the stated reference usually through the calibration of the measurement and test equipment used to 14 NIST Handbook 150-1:2010

conduct the test. Calibration is achieved with the use of a reference standard having a known value(s) and uncertainty and with established traceability to a national metrology institute. The laboratory shall determine equipment calibration intervals based on the equipment s frequency of use and the environment in which it is used, and also in accordance with standard test methods and/or manufacturer s recommendations. 5.6.2 Proper performance and calibration of measurement and test equipment shall be periodically verified as needed through the use of cross-checks and working standards for the individual measurement and test equipment units. The periodical verification shall be documented. 5.6.3 Ultimately, the laboratory shall be responsible for the determination and documentation of test and measurement equipment calibration, including the calibration interval. The laboratory shall have a documented procedure to deal with nonconforming work if test and measurement equipment is found to be out of calibration through the use of cross-checks and working standards. 5.6.4 The reference standards used and the environmental conditions at the time of calibration shall be documented for all calibrations. 5.6.5 The following requirements apply for calibrations and calibration certificates. a) Certificates shall be required for calibrations performed by outside services. A calibration certificate shall indicate uncertainty or accuracy tolerance limits, and traceability of reference standards. Certificates from accredited outside service providers shall include the accreditation body logo or reference to the accreditation body, and records shall be kept showing that the accreditation is current. b) Certificates shall be required when a laboratory performs its own calibration. If the testing laboratory performs its own calibration, the identity of the properly trained personnel involved, the standard metrological procedures used, the environmental conditions, and the measurement uncertainty shall be documented. Evidence and demonstration of traceability as required in NIST Handbook 150, Annex B, shall be documented. Records shall contain sufficient information to permit repetition of the calibration. c) Laboratories using standard reference lamps and/or standard photometers shall document each step of the traceability chain and, for each step, the magnitude of the associated uncertainty as stated on their calibration certificates (or the uncertainty as determined [or estimated] by the laboratory if it is an in-house calibration conducted by the laboratory). 5.7 Sampling Appropriate sampling plans and procedures shall be included in the management system when sampling is required by the test method or when the laboratory is required to sample. 5.8 Handling of test and calibration items There are no requirements additional to those set forth in NIST Handbook 150. NIST Handbook 150-1:2010 15

5.9 Assuring the quality of test and calibration results 5.9.1 The laboratory shall conduct a test after every calibration to assure and validate that the calibration of the system is acceptable. NOTE One way to verify calibration is to measure a check lamp. Measured values of the check lamp should be within predefined limits, e.g., <1 % for lumen output. 5.9.2 The laboratory shall have a documented method to assure that the check lamps used to verify calibration results are valid; i.e., the measured values have not changed but are within a given limit of repeatability. NOTE One way to assure the required reproducibility of the check lamp is to use three lamps to check calibration results. Measured values of all three lamps shall be within a predetermined limit of their previous values. 5.9.3 The laboratory shall document the frequency or schedule at which check or working standards are measured. 5.9.4 The laboratory shall have a documented procedure to deal with nonconforming work if retest or recalibrations of check or working standards are found to be out of the documented acceptable range. 5.9.5 Procedures for the laboratory s participation in NVLAP proficiency testing, including analyzing and monitoring the laboratory s results, a description of any corrective actions taken because of the results, and procedures for comparing the laboratory s proficiency test results with those from NIST or other NVLAP-accredited laboratories shall be documented. 5.10 Reporting the results 5.10.1 General Test reports shall clearly reference the test method and edition, including the published year, applied to the product or system tested. 5.10.2 Data analysis and report generation 5.10.2.1 The laboratory personnel responsible for report writing and generation shall be available during the laboratory s on-site assessment to be interviewed by the assessor for evaluation of the laboratory s compliance with the NVLAP criteria for test reports. 5.10.2.2 At times, the final report may be written and generated at an off-site facility that is located some distance from the testing laboratory such that the assessor cannot interview the off-site personnel. In such a case, the laboratory shall have in place for assessor review appropriate written descriptions in the management system documentation of procedures and documentation for assuring the accuracy and validity of the data transmission, the incorporation and accurate analysis of the data in the test report, and the compliance of the test report with NVLAP criteria. Depending on the on-site laboratory evaluations of these written descriptions, a visit to the off-site facility may be required. When warranted, an assessor shall visit the off-site facility at additional cost to the laboratory before accreditation is granted or renewed. 16 NIST Handbook 150-1:2010

5.10.2.3 If a laboratory uses several organizational departments for the discrete functions of testing, data collection, data processing, and test report preparation and generation, it is necessary that lines of responsibility with distinct supervisory positions be defined and that no conflicts exist. The assessor shall review the procedures and documentation of the lines of responsibility with distinct supervisory positions during the on-site assessment, and also shall verify that all NVLAP requirements regarding the writing and storage of reports are followed.
