Foreword
This document (CEN/TR 16496:2013) has been prepared by Technical Committee CEN/TC 351
“Construction products - Assessment of release of dangerous substances”, the secretariat of which is
held by NEN.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such
patent rights.
This document has been prepared under a mandate given to CEN by the European Commission and
the European Free Trade Association.
This Technical Report gives guidance for the selection and integration of the recommended horizontal
product testing protocols on dangerous substances harmonised by CEN/TC 351 into hENs and EADs.
Since the work in CEN/TC 351 in cooperation with the European Commission and its Expert Group on
Dangerous Substances (EGDS) and the product TCs is a work in progress, some subjects and issues
remain open for the time being. However, the results of the work of CEN/TC 351 are now mature
enough for practical implementation in product standards and EADs.
This document takes into account relevant information that had become available by March 2013
through the activities in the working groups and task groups of CEN/TC 351 as well as the guidance
provided by the European Commission.
This document is intended as easy-to-use guidance especially for product TCs and EOTA Working
Groups (or equivalent groups under the Construction Products Regulation). Where reference is made
to ‘Product TCs’, EOTA WGs are also meant where appropriate.
1 Introduction
1.1 General
The Construction Products Directive 89/106/EEC (CPD) contained six essential requirements for
works that gave rise to a number of 'essential characteristics' for products that had to be covered by
European Technical Specifications (ETS) for construction products (harmonised European Standards
(CEN) and European Technical Approvals (EOTA)). As derogation from this rule, essential
requirement No 3 “Hygiene, health and the environment” (ER3) was dealt with via a convention in the
ETS which did not take it directly into account, mainly due to the absence of European harmonised
test methods. In order to solve this problem, the European Commission gave CEN, the European
Committee for Standardization, a mandate (M/366) in 2005 to develop European harmonised test
methods for the assessment of release or emission of dangerous substances from construction
products.
From July 2013 the CPD has been replaced by the Construction Products Regulation (Regulation (EU)
No 305/2011, CPR). The fundamental principles of the CPR are the same as for the CPD. The CPR
now refers to basic requirements for construction works (BRCWs) instead of ERs, but the same six
functional requirements as for the CPD are still there, supplemented by a seventh, the “Sustainable
use of natural resources”, and BRCW 3 is extended to the construction and demolition phase.
However, it is expected that the work in CEN/TC 351 according to mandate M/366 will be carried out
under the terms and conditions of the CPD with a focus on release and emission in the use phase of
construction works.
Mandate M/366 requires that CEN develops horizontal test methods that, as far as possible, are based
on existing test methods. This means that European harmonised test methods will not be developed
for each construction product separately. The methods should be preferably applicable to all
constructions products as defined in the CPR as far as they are covered by BRCW 3. The intention is
to avoid the unnecessary and onerous development of product specific test standards for a multitude
of construction products and to minimise the amount of costly testing. The horizontal approach is
described in detail in CEN/TR 16098.
Furthermore, according to the guidance of the EC (Decision 192, CEN/TC 351 meeting in Berlin on
2013-02-11/12), CEN/TC 351 is asked to provide horizontal methods reflecting the state of the art.
Different test methods or testing options can be considered by CEN/TC 351 when technically justified
because of different conditions of use, different end uses or product characteristics, but not because of
differences in regulations.
In order to apply the horizontal test methods correctly to individual construction products, some
product specific additions remain necessary. For example, aspects such as pre-treatment and
preconditioning of test specimens cannot be completely specified horizontally but require product
specific additions. The necessary product specific additions to the horizontal test standards must be
included in the harmonised product standards for the implementation of BRCW 3.
The European Commission has recently amended ten and is currently amending some further existing
construction product mandates issued to CEN to include detailed requirements for BRCW 3. The
updated mandates include the requirements for each harmonised product standard. For each hEN or
mandated prEN, the relevant release/emission scenarios and the relevant regulated dangerous

substances are listed. The CEN product TCs are obliged to amend their product standards using the
mandate amendments as a checklist for including BRCW 3-related requirements.
This Technical Report (TR4 of mandate M/366) gives instructions on which aspects related to the
horizontal test methods are important to address when amending product standards. The report is
intended as guidance for CEN product TCs for the revision of product standards in regard to
dangerous substances. The report focuses on the use of the harmonised test standards. The

possibilities to avoid testing through the use of e.g. descriptive elements like positive or negative lists
in product standards are not covered by this report. With respect to this issue, the product TCs may
consult the guidance given by the European Commission including the amended product mandates.
The examples described in Annex A and Annex B show how the guidance given in this Technical
Report can be adopted in a product standard. They illustrate a possible way to implement the
horizontal test standards of CEN/TC 351 into product standards by product TCs. The examples are
inspired by work in progress on existing harmonised product standards. Their intention is to provide
generic, non-product specific assistance; they are not the only possible solution confirmed by the
powers that be.
1.2 Mandate amendment for BRCW 3 and the product TC’s answer
The European Commission describes in the amendments to the various product mandates for
dangerous substances the tasks the product TCs are expected to carry out, when preparing an
answer to the mandate amendment. Hereunder, as an example, the relevant text from mandate

Description of the mandated work
The attached annex provides an overview on national notified regulatory requirements that have been
linked by several experts of the Commission’s expert group on dangerous substances to products
covered under mandate M/103.
CEN/TC 88 has to assess the list and to take it completely into consideration when describing and
justifying its selection of substances and their relevance in its work programme, in particular on the
following aspects:
− If these substances may be present in products covered by mandate M/103 and in all existing
harmonised product standards or harmonised product standards under development;
− If these substances are likely to emit from the above mentioned products and if these emissions

− If there is available data, particularly where the above mentioned products have been tested in the
