The Construction Products Directive (CPD) will in 2013 be replaced by the Construction Products Regulation (CPR), which extends into recycling and end of life aspects. The development of appropriate standards has been taken up by CEN/TC 351, where a horizontal approach to testing is promoted to avoid multiplication of test protocols per sector. In parallel, IPTS-JRC is developing criteria for End of Waste (EoW). Redundant testing shall be avoided. Dossiers are being drafted to allow declaration of “without further testing” (WFT) for products as a whole, or for specific regulated substances potentially released from products. These dossiers call for information and test data on the wide variety of products covered by harmonised European standards. Experience has been gained with a range of products over the past decade. This information has been compiled in LeachXS™ Lite, which has been developed with support of US EPA for use in combination with the new EPA leaching test methods (same as CEN methods). In this abstract, recycled concrete, municipal solid waste incinerator bottom ash and basic oxygen steel slag are presented to be used by end users for comparison purposes. Additional benchmark cases are under development.
