scope:

This CEN Technical Report describes a procedure for assessing construction products with regards to their release/emission of regulated dangerous substances (RDS) into the environment in accordance with Essential Requirement Number 3 of the Construction Products Directive (CPD), as far as these construction products fall under the responsibility of CEN. This Technical Report defines how the mandated characteristics expressed in terms of mandated RDSs for each construction product can be assessed by an individual manufacturer using the 'Without Testing' (WT) procedure and/or the 'Without Further Testing' (WFT) and 'Further Testing' (FT) procedures after an initial type assessment and how the corresponding information accompanying the CE marking can be expressed in terms of declared values or RDS classes. This report describes: a) under which conditions a RDS class for a construction product may be declared by the individual manufacturer using the 'Without Testing (WT)' assessment procedure; b) if all relevant mandated RDSs are assessed by this Without Testing procedure, how a set of RDS classes for a construction product may also be declared by the manufacturer without the need for testing of their specific products; c) how to establish RDS classes for a construction product using a Without Further Testing procedure once sufficient information has been obtained from initial type testing; d) when and how to undertake Further Testing as part of factory production control; e) how to evaluate conformity of the construction product to one or more RDS classes; f) how to create and declare a set of RDS classes using one or a combination of the WT, WFT and FT procedures. For construction products that have to be tested, horizontal European release/emission test methods are the reference methods, but this report also describes under which conditions screening tests may be used. The use of alternative tests is part of the standard CPD procedure and therefore the use of alternative tests is not described in this report.
