CE-marking of solid wood products

Transcription

1 Norsk Treteknisk Institutt 1 CE-marking of solid wood products Audun Øvrum, Norwegian Institute of Wood Technology (NTI) CE-marking is the manufacturer's declaration that a product complies with the essential requirements of the relevant European health, safety and environmental protection legislation, in practice by many of the so-called Product Directives. For wood products it is the Construction Products Directive (CPD) that sets the requirements. In general CE-marking is a mean for free access for the product in the European Economic Area. It is not a quality mark, but depending on the use of the product, some quality aspects may be included in the CE-marking A manufacturer must perform two things to be allowed to make a declaration for a product. 1. The product must be tested in an Initial type test (ITT) to determine the performance of the product. 2. The manufacturer must perform a factory production control (FPC) to ensure that all produced products conform to ITT. Every product that the manufacturer brings on to the market must conform to the ITT. Both the ITT and FPC are defined in a technical specification. This technical specification can either be a harmonized product standard, or a European technical approval (ETA). The latter is usually obtained by using a European technical guideline (ETAG). For the sawmilling industry technical specifications have the form of harmonized standards. In these standards a system for attestation of conformity is outlined. There are several levels of attestation of conformity, and some levels require an involvement of a notified body to certify some of the tasks in the attestation of conformity. The responsibility will however always be on the manufacturer. A quick summary of these levels are: System 4 System 3 System 2/2+ System 1/1+ No Notified Body, manufacturer performs every task Test labs do the ITT FPC certified by a notified body Product certificate by a notified body Notified bodies (NB) are independent third party bodies that are appointed nationally. These bodies can act in the whole European Economic Area, and a ce-marking of solid wood products

2 Norsk Treteknisk Institutt 2 manufacturer is free to choose whatever NB he or she wants regardless of nationality of both manufacturer and NB. The practical implementation of CE-marking is in sum for a manufacturer like this: 1. Make an initial type test and establish a factory production control for the product 2. Depending on the product, certify the factory production control or get a Certification of product conformity. 3. Declare the properties relevant for the product on the product itself, on a label attached to it, on the packaging or in the accompanying documentation. 4. Make a declaration of conformity. 5. Affix the CE-marking There are numerous wood products which already have, or in near future will have, a harmonized standard which make CE-marking possible. The most common products from saw mills and planer mills are structural timber, wood flooring and panelling and cladding. Structural timber is defined in AoC level 2+ in EN 14081, and requires marking on every piece of timber. The quality requirements are strength class, some requirements on deformation, fissures, wane, biological features and deviation of dimensions. There are no specific requirement on moisture content. This standard is compulsory from Wood flooring is defined in AoC-level 4 in EN 14342, and requires no marking of pieces, just on accompanying documentation. You should follow one of nine product standards, which gives some technical requirements on the product like grading, dimensions, moisture content, deviations and so on. This standard is compulsory from Panelling and cladding is defined in AoC-level 4 in EN 14915, and requires no marking of pieces, just on accompanying documentation. It is not required to follow any product standard, which again results in no technical requirements on the product. This standard is compulsory sometime in For some products and countries additional marking may be relevant. This is allowed, but this additional marking must give added value to the customer either by a higher AoC level, or higher quality requirements on the product. The additional marking must be voluntary and transparent, and must not be in contradiction, or be confused with the CE-marking. ce-marking of solid wood products

5 The manufacturer's declaration that the product complies with the essential requirements of the relevant European health, safety and environmental protection legislation, in practice by many of the socalled Product Directives. For wood products the Construction Products Directive (CPD)

6 Six essential requirements shall be addressed ER 1 ER 2 ER 3 ER 4 ER 5 ER 6 Mechanical resistance and stability Safety in case of fire Hygiene, health and environment Safety in use Protection against noise Energy economy and heat retention

7 Is obligatory for every construction product placed on the European Market and is based upon: Initial type test To determine the performance of the product type Factory production control The permanent internal control of production exercised by the manufacturer to assure that all produced products conform to ITT Every product brought onto the market must conform to the Initial Type Test.

8 Declare the properties relevant for the product on the product itself, on a label attached to it, on the packaging or in the accompanying documentation Make a declaration of conformity Shall be supplied to the customer on demand Depending on the product certify the factory production control Depending on the product get a Certification of product conformity

27 * Wood based panels have been CE-marked for some years Some producers have started CE-marking of truss rafters Wood flooring companies are implementing CE-marking as we speak Some producers of structural timber will be ready for CE-marking before Christmas Panelling and cladding probably in the end of next year

28 " Conditions Added value through: Higher AoC level Higher quality requirements on the product No contradiction or confusion with CEmarking Voluntary Transparent Is relevant for some countries and some products

29 + " Not yet Additional marking will be required by some customers still By time CE-marking might be the only conformity assessment for most products
