European foreword
This document (CEN/TR 17304:2018) 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 shall not be held responsible for identifying any or all such patent rights.
This document has been prepared under a standardization request given to CEN by the European
Commission and the European Free Trade Association.
Introduction
This document was developed under the remit of Commission Regulation (EU) 2016/1017 of
23 June 2016 amending Annex XVII to Regulation (EC) No 1907/2006 of the European Parliament and of
the Council concerning the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH)
as regards inorganic ammonium salts [1].
This document is derived from the horizontal standard EN 16516 [2] which specifies the horizontal
reference method for testing the emission (release) of dangerous substances from construction products
into indoor air.
This method uses a test chamber in which emissions are generated under conditions which are kept
constant during the test.
1 Scope
This document specifies a method for the determination of emissions of ammonia from cellulose
insulation products into indoor air at 90 % relative humidity (RH). It is based on the use of an emission
test chamber and subsequent analysis of ammonia in test chamber air.
