4 Construction Products Directive A BACKGROUND The first document prepared by the GEPVP explained the background to compliance with the CPD 1 and the second explained the principles of evaluation of conformity 2. This document will explain the system of Evaluation of Conformity applicable for laminated glass and laminated safety glass as laid down in EN , the appropriate harmonised European Standard (hen). B AUDIENCE This part is applicable to any manufacturer of laminated glass and laminated safety glass. C SCOPE This is taken from EN This European Standard covers the evaluation of conformity and the factory production control of laminated glass and laminated safety glass for use in buildings. D METHODOLOGY (see also summary figure 1) 4 This document follows the methodology given in the second document. It also follows the same referencing with respect to attachments, etc. This document includes explanatory information on Clause ZA.2.2 EC Certificate and Declaration of Conformity (see Attachment 6). Annex ZA As detailed in the second document the starting point for undertaking the evaluation of conformity is Table ZA.1. This table is colour coded and each essential characteristic is numbered to line up with the corresponding table in the second document. The Systems of Attestation of Conformity for the claimed intended uses are given in Table ZA.2 of the hen. Details of the tasks relating to Assignment of Evaluation of Conformity are given in Tables ZA.3.1 to ZA.3.3 of the hen (see second document for explanation). The relationship between the intended use, the applicable Systems of Attestation of Conformity and the roles of the manufacturer and Notified Body(ies) is given in Figure 2. This figure is specific to conformity with EN When a manufacturer has finalised the collection of all applicable information then he can proceed to CE Marking. This is detailed in Clause ZA.2.2 (see Attachment 6). Based on the manufacturer s Declaration of Conformity is the CE Marking label. Examples of CE Marking labels for different laminated glass and laminated safety glass products with different intended uses/characteristics and hence Systems of Attestation of Conformity are shown in Figures 3, 4, 5 and 6. 1 GEPVP CONSTRUCTION PRODUCTS DIRECTIVE A guide to CE marking for glass in building 2003 onwards 2 GEPVP CONSTRUCTION PRODUCTS DIRECTIVE Evaluation of conformity as laid down in the harmonised European Standards (hens) 3 EN Glass in building Laminated glass and laminated safety glass Evaluation of conformity/product standard

The substituting materials and/or components can be added to the product family and also the product description when compliance has been demonstrated. 9 The terms manufacturer and producer are understood as being synonyms (see CPD working document NB-CPD/02/019 issued 24 April 2002 page 1)

13 Evaluation of conformity of 4.2 Conformity with the definition of laminated glass and laminated safety glass General Products shall conform with the manufacturer s product description and fulfil the definition and requirements of laminated glass or laminated safety glass (see and 4.2.3) Conformity with definition of laminated glass Products shall fulfil the definition and requirements for laminated glass as defined in EN ISO Conformity with definition of laminated safety glass Products shall fulfil the definition and requirements for laminated safety glass as defined in EN ISO Determination of the characteristic s performances Characteristics of laminated glass and laminated safety glass General The characteristics of laminated glass and laminated safety glass are those of the glass panes used as components (see ) Characteristics of the glass panes used as components for the production of laminated glass and laminated safety glass The glass types given in Table 1 can be used for the manufacture of laminated glass and laminated safety glass. The characteristics of the glass components are listed in Table 2 and the values can be found in the appropriate product standards, e.g.; EN 572-1, EN , etc. For the characteristics listed in Table 2, for the glass pane types, generally accepted values or calculated values shall be used. Since the majority of the characteristics of Table 2 are not changed significantly by the laminating process they shall be used for laminated/laminated safety glass EN ISO clause 4 details the durability testing for laminated glass. The test methods and the evaluation of results are given in EN ISO EN ISO clause 4 details the durability testing for laminated safety glass. The test methods and the evaluation of results are given in EN ISO

14 Construction Products Directive Determination of characteristics of laminated glass and laminated safety glass 14 If the laminated glass and laminated safety glass manufacturer wishes to claim that any performance characteristic is independent of the production equipment used then the factory production control system shall be in accordance with this standard including his specific process control conditions Safety in the case of fire Resistance to fire (1) Fire resistance shall be determined and classified in accordance with EN Safety in the case of fire Reaction to fire (2) Reaction to fire shall be determined and classified in accordance with EN Safety in the case of fire External fire behaviour (3) Where the manufacturer wishes to declare external fire performance (e.g. when subject to regulatory requirements), the product shall be tested and classified in accordance with EN Safety in use Bullet resistance: Shatter properties and resistance to attack (4) Bullet resistance shall be determined and classified in accordance with EN Safety in use Explosion resistance: impact behaviour and resistance to impact (5) Explosion resistance shall be determined and classified in accordance with EN Glass CANNOT be tested for resistance to fire on its own. The tests have to be undertaken in a glazed assembly. The glazed assembly is regarded as a virtual assembly 10 and is detailed in the official classification report. The reaction to fire performance is influenced by the amount of organic component, i.e. type and thickness of interlayer, plastics glazing sheet material. Work is in progress on determining this characteristic for these products on a Classified without further test basis. The present situation is that there are four different test methods in ENV The applicability of these tests to glass is not totally clear. However, before deciding to test it is paramount that the manufacturer checks if a particular glass product type is permitted, by national regulations, in this application. Laminated glass/laminated safety glass has to be tested for this characteristic. A product that can be classified should also be capable of being classified as a laminated safety glass. Laminated glass/laminated safety glass has to be tested for this characteristic. A product that can be classified should also be capable of being classified as a laminated safety glass. 10 Sectorial Group 09 Glass in building: Determination of the fire resistance performance of glazed assemblies (Virtual Assemblies)

15 Evaluation of conformity of Safety in use Burglar resistance: Shatter properties and resistance to attack (6) Burglar resistance shall be determined and classified in accordance with EN Safety in use Pendulum body impact resistance: Shatter properties (safe breakability) and resistance to impact (7) Pendulum body impact resistance shall be determined and classified in accordance with EN Note: Laminated glass conforming with EN ISO (No EN classification) will be declared Safety in use Mechanical resistance: Resistance against sudden temperature changes and temperature differentials (8) The resistance against sudden temperature changes and temperature differentials is a generally accepted value. That value is given in the standards (see Table 1) for the appropriate glass substrate Safety in use Mechanical resistance: Resistance against wind, snow, permanent load and/or imposed loads of the glass unit (9) Laminated glass/laminated safety glass has to be tested for this characteristic. A product that can be classified should also be capable of being classified as a laminated safety glass. This characteristic only need to be determined for laminated safety glass (see EN ISO ). Laminated glass is declared. This characteristic, i.e. resistance to breakage due to thermal stresses, is dependent on the glass substrates. However, excessive high temperatures may cause deterioration of the laminated glass/ laminated safety glass interlayer(s). 15 The ordered assemblies of laminated glass or laminated safety glass (thickness and types of glass components or plastics glazing sheet materials interlayers) shall ensure the resistance against wind, snow, permanent load, and other mechanical, (quasi-) static action, which shall be checked in accordance with design standards 11. As long as on the concerned construction or building site no part of the design standards is applicable for the design then the current method of determining mechanical resistance in the country of destination shall be applied. This characteristic will be dependent on the glass substrates, plastics glazing sheet materials, interlayer types and degree of adhesion of the interlayer(s) to the glass substrates and plastics glazing sheet materials. Note: pren will give information on the load carrying capacity of laminated/laminated safety glass as well as a method for determining the strength of laminated/laminated safety glass constructions from first principles. The manufactured or supplied thickness of laminated glass or laminated safety glass shall conform to the ordered thickness. Supplying what was ordered, in terms of thickness, will cover this characteristic. 11 pren 13474: This standard is being drafted. It will consist of the following three parts: - determination by calculation of the resistance to load of glass used in fenestration; - determination by calculation of the resistance to load of glass used in common non-structural applications other than fenestration; - general basis of design.

16 Construction Products Directive Protection against noise Direct airborne sound reduction (10) The sound reduction indexes shall be determined in accordance with EN Energy conservation and heat retention Thermal properties (11) EN gives generally accepted values for certain constructions of laminated safety glass. However, for specialist products this characteristic should be determined. The thermal transmittance value (U-value) shall be determined by calculation in accordance with EN 673 with: emissivity ε: the declared value of the glass manufacturer. If the information is not available, the emissivity shall be determined in accordance with EN nominal thickness of the glass panes Energy conservation and heat retention Radiation properties: Light transmittance and reflectance (12) This value needs to be calculated in accordance with EN 673. These values need to be determined in accordance with the standard EN The light transmittance and reflectance shall be determined in accordance with EN Energy conservation and heat retention Radiation properties: Solar energy characteristics (13) If the properties of the component panes and interlayer materials are known then the performance of the laminated/laminated safety glass can be calculated. These values need to be determined in accordance with the standard EN 410. The solar energy transmittance and reflectance shall be determined in accordance with EN 410. If the properties of the component panes and interlayer materials are known then the performance of the laminated/laminated safety glass can be calculated.

18 Construction Products Directive Attachment 2: hen Clause 5 Evaluation of conformity Initial type testing of laminated glass and laminated safety glass General To establish if a product conforms to the definition of laminated glass or laminated safety glass, initial type testing shall consist of: determining that the laminated safety glass material design conforms to EN ISO determining that the laminated glass material design conforms to EN ISO Test specimens This testing is specified in the appropriate part of EN ISO Laminated safety glass in Part 2 and laminated glass in Part 3. The test methods to be used and method of evaluation of results are defined in EN ISO The test specimens for the initial type test shall conform to the minimum specification(s) of the product family design for a specific intended use/characteristic (see to ). NOTE 1 When the intended uses comprise bullet resistance, explosion resistance and/or burglar resistance, and the product is to be defined as a laminated safety glass then the classification according to EN can be undertaken on test specimens that consist of two glasses, thickness 3mm nominal, separated by an interlayer, thickness 0,76mm nominal. When for a type of glass no 3mm nominal exists, the nearest thickness shall be used. When for a type of interlayer no 0,76mm nominal exist, the nearest thickness shall be used. The test specimens for the radiation test (see Clause 6 of EN ISO :1998) shall conform to the minimum specification of the product family related to interlayer type. The test specimens must be representative of a specific product family for an intended use/ characteristic. For example: Laminated safety glass using a pvb interlayer can be classified using a 0,38mm interlayer; A fire resistant laminated glass produced using an intumescent interlayer must be tested on the thinnest product that can be classified; If a bullet resistant, explosion resistant or burglar resistant glass is to be specified as a laminated safety glass then the EN testing should take account of NOTE 1. NOTE 2 The necessity for undertaking the radiation test can be overcome if appropriate test reports are supplied by the interlayer supplier Initial type testing (ITT) of characteristic s performances All characteristics in shall be subject to initial type testing in accordance with NOTE Annex D includes information on those changes that may require a new ITT.

20 Construction Products Directive Attachment 6: hen Annex ZA Clause ZA.2.2 EC Certificate and Declaration of Conformity Depending upon the intended use of the product and hence the applicable System of Attestation of Conformity will be the extent to which this clause applies. 1. Products with System of Attestation of Conformity 1; This System of Attestation of Conformity requires the involvement of a Notified Certification Body (NCB). It is the responsibility of the NCB, when they are satisfied that compliance with the conditions of the Annex ZA has been achieved, to produce a Certificate of Conformity (EC Certificate of Conformity). This certificate allows the manufacturer to affix the CE Marking (see Figure 3). The detail of what is to be included in the certificate is given in the hen. When the manufacturer has the Certificate of Conformity then a Declaration of Conformity (EC Declaration of Conformity) has to be produced. The detail of what is to be included in the declaration is given in the hen. 2. Products with System of Attestation of Conformity 3; 20 This System of Attestation of Conformity only requires the involvement of a Notified Body (NB) with the Initial Type Testing of the product. When the manufacturer is satisfied that compliance with this Annex has been achieved then a Declaration of Conformity (EC Declaration of Conformity) is prepared. This declaration allows the manufacturer to affix the CE Marking (see Figure 5). The detail of what is to be included in the declaration is given in the hen. 3. Products with System of Attestation of Conformity 4; This System of Attestation of Conformity does not require the involvement of a Notified Body (NB). Therefore when the manufacturer is satisfied that compliance with this Annex has been achieved then a Declaration of Conformity (EC Declaration of Conformity) is prepared. This declaration allows the manufacturer to affix the CE Marking (see Figure 6). The detail of what is to be included in the declaration is given in the hen. Duplication of information between the certificate, where applicable, and the declaration should be avoided. This can be done by cross-referencing between documents if one contains more information than the other. EC Declaration of Conformity and, if applicable, the EC Certificate of Conformity shall be presented in the official language or languages of the Member State in which the product is to be used.

21 Evaluation of conformity of Attachment 7: hen Other Annex(s) Annex B (informative) Tests for factory production control Clause No. Content Explanation B.1 General During production testing of the laminated glass/ laminated safety glass should be undertaken to ensure that the product is durable. These tests are detailed in B.2. The manufacturer should also submit the production to a regular testing to check conformity of the product with the samples submitted for Initial Type Testing. These tests are detailed in B.3. B.2 Production durability check The purpose of the check is to determine if the laminating process has been successfully performed. The specific test undertaken will be dependent on the following: a) Whether the product is a laminated glass or a laminated safety glass b) The interlayer type c) The intended use of the product See Table B.1. B.3 Regular conformity check of the product The purpose of the check is to determine if the product continues to conform to the ITT. The specific test undertaken will be dependent on the following: a) Whether the product is a laminated glass or a laminated safety glass; b) The interlayer type; c) The intended use of the product. See Table B.2. B.4 Details of test methods B.4.1 B General Introduction The concept of the Construction Products Directive is that the product placed on the market shall be as good as or better than the product tested during the ITT. These tests are designed to ensure that production has ongoing conformity. Tests designed to check the production process has been performed correctly. Ongoing conformity checks. Means of ensuring product performance continues. 21 B to B The test methods have been taken either from EN ISO or have been developed especially. They will enable a manufacturer to check that his process control has been successful and that the products comply. Details of the test methods are given in Table B.3. Details of test methods A to D Detailed requirements for the different test methods.

22 Construction Products Directive B.5 Testing protocol B.5.1 B to B B.5.2 B Frequency Test methods A to D Specimen selection General Detailed requirements for the different test methods B to B The test specimens should, where applicable, conform to the minimum specification(s) of the product family design for a specific intended use/ characteristic (see to ). Test methods A to D B.6 Outcome of testing B.6.1 General Detailed requirements for the different test methods 22 B.6.2 to B.6.5 The results of the testing to test methods A and B will enable the manufacturer to decide if the product can be regarded as non-conforming. The action by the manufacturer in the result of a failure will depend on the glass type and intended use. Test methods A to D B.7 Other testing The tests covered by B.2 and B.3 are a means of ensuring ongoing compliance of the factory production control. However, none of the tests check the mechanical performance of the laminated safety glass. Therefore at least once per week a minimum of 3 test specimens should be subjected to a mechanical performance test. Detailed outcomes for the different test methods NOTE Annex C lists a number of test methods that a manufacturer could employ to demonstrate ongoing mechanical performance.

24 Construction Products Directive Annex C (informative) L aminated safety glass: Mechanical resistance tests Clause No. Content Explanation C.1 General 24 The tests for ensuring conformity given in Annex B do not always act as a good indicator of the future mechanical behaviour, i.e. safety in use performance resistance. The tests, in Annex B, give an insight into the effectiveness of the laminating process. However, the mechanical behaviour of the assembly is as a result of the inherent properties of the interlayer, sometimes referred to as tenacity, and the adhesion of the interlayer to the other components of the assembly. A number of mechanical tests have been used to check that the laminated safety glass will offer the expected performance. Laminated safety glass is expected to have specified mechanical behaviour. The test methods given below may be used as product conformity tests. There is no requirement for any particular test to be undertaken. However, if any test is chosen then its relationship to the performance of the product during ITT must be shown. C.2 Ball drop test Apparatus, test method and evaluation of results given. C.3 Pendulum impact test Apparatus, test method and evaluation of results given. C.4 Others C.4.1 General C.4.2 C.4.3 C.4.4 There is not yet a fully defined test method for determining the tenacity of the interlayer or the adhesion of the interlayer.

25 Evaluation of conformity of Annex D (informative) Criteria for deciding if a change within an assembly requires a new initial type test Clause No. Content Explanation D.1 General discusses the requirement for initial type testing the characteristics of the laminated glass and laminated safety glass. The general rules for initial type testing are given in ). However, there will be circumstances when due to changes in the material design, e.g. change of components, changes in thickness, alteration of the stacking order, etc., that the new design is outside the product description/product families and will require a new initial type test. Table D.1 offers advice as to those alterations that require consideration of a new initial type test. The advice in Table D.1 relates to specific intended uses/ characteristics. Changes in the product may occur that could result in it no longer complying with the product description and/or specified product family. In this case there may be a requirement for the new product to be subjected to the ITT. This need is specific to the intended use of the product details the use of generally accepted values, calculated values etc., that should be considered before undertaking any actual testing.
