CEN established in November 2005 a new Technical Committee (CEN/TC) with number 351 and the title "Construction products: Assessment of release of dangerous substances".
The secretariat of CEN/TC 351 is held by NEN Construction. This TC will adopt assessment methods with which information may be given in the CE marking of construction products on the release of dangerous substances in the use phase.
One of the stakeholders in CEN/TC 351 is ECOS, the European Environmental Citizens Organisation for Standardisation. The attached paper presents the ECOS view on the work of CEN/TC 351.
When Belgium had the Presidency of the European Commission, in the second half of 2010, a high level meeting on Product Policy and Indoor Air Quality took place in Brussels, eutrio. NEN has been involved in the organisation of this event.
In the Newsletter of DIN, an article on CEN/TC 351 and its work has been published by the German delegation to CEN/TC 351. The paper introduces the standardisation work of CEN/TC 351 and the associated implications for the technical committees for construction products. The paper is in the German language and can be downloaded for 8 euros from http://www.beuth.de

Now that the methods for leaching, content and analysis are (almost) validated for their robustness, the second step of the validation process is launched. This exercise is organised by the Joint Research Centre of the European Commission in Geel (BE). Interested laboratories can report to the project leader, thomas.linsinger(at)ec.europa.eu. The work programmes and the registration form are in document CEN/TC 351 N 0672
The draft horizontal methods of CEN/TC 351 are validated for their robustness, before they are published as CEN/TSs. The CEN/TSs are the basis for the second step of the validation process, on repeatability and reproducibility. The reports of the robustness validation are published as CEN/TC 351 reports, to provide wide availability of the test data.
Report from the CEN/TC 351/WG 1 consortium on the validation of the leaching methods (TS-2 Dynamic surface leaching test en TS-3 Up-flow percolation test).
Report from the CEN/TC 351/WG 1 consortium on the additional validation of the up-flow percolation test (TS-3). In this revised version, some minor mistakes have been corrected. They don’t influence the conclusions.
Report from Susset, Dijkstra and Van Zomeren on the Technical principles underlying limit values for release of substances for the percolation test TS-3: comparison DE and NL
Report from the CEN/TC 351/WG 2 consortium on the validation of prCEN/TS 16516 "Construction products – Assessment of emissions of regulated dangerous substances from construction products".
Report from the CEN/TC 351/WG 2 consortium on the validation of ammonia test methods as supplement to EN 16516 "Construction products: Assessment of dangerous substances - Determination of emissions into indoor air".
Report from the CEN/TC 351/WG 3 consultant on the validation of the draft TS 00351014 “Construction products: Assessment of release of dangerous substances – Determination of activity concentrations of radium-226, thorium-232 and potassium-40 in construction products using gamma-ray spectrometry”.
Report from VITO on the validation of the draft methods for analysis of As, Sb and Se in eluates and digests from construction products.
Report from ALS Global on the validation of the draft methods for analysis of anorganic substances (other then As, Sb and Se) in eluates and digests from construction products.
Report from VITO on the validation of the draft methods for analysis of organic substances in eluate and digests from construction products.
The following list of terms provides definitions of terms related to the CPR (EU/305/2011) which are relevant for the work of CEN/TC 351 “Construction Products - Assessment of release of dangerous substances”. They refer to the regulatory background and the organizational structure of the use of the test methods developed in CEN/TC 351.
The definitions were either taken directly from the CPR or developed by CEN/TC 351 Working Group 4 “Terminology”. As it might cause problems to integrate definitions which legal interpretation might change or is not yet completely fixed into the terminology standard of CEN/TC 351 (prEN 16687), the TC decided in conjunction with the European Commission to publish the terms at the website of the EU in the existing glossaries. Awaiting that, the definitions are provided at the website of CEN/TC 351 (www.centc351.org).
For further terms relevant for the work of CEN/TC 351 and related to the testing of the release of dangerous substances from constructions products into soil and groundwater or indoor air, to the measurement of their content in construction products or to radiation, see prEN 16687 (under development).
