Attention i
19、s 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 E
20、uropean Free Trade Association. This Technical Specification was elaborated on the basis of CEN/TS 15863 1, which is based on NEN 7375:2005 2. This Technical Specification specifies a dynamic surface leaching test for determination of surface dependent release of substances from monolithic or plate-
21、like or sheet-like construction products or granular construction products with low hydraulic conductivity under standardized conditions. CEN/TS 16637-1 deals with the determination and use of test methods for leaching of construction products taking specific situations into account. Technical Speci
22、fication FprCEN/TS 16637-3 (in preparation) specifies an up-flow percolation test to determine the leaching behaviour of granular construction products under standardized percolation conditions. Background information on characterization of leaching behaviour of construction products can be found in
