scope:

This European Standard describes three laboratory tests to determine the reducing character and the reducing capacity of building and waste materials or their eluates. For a specification of the materials with which experience has been acquired with the execution of the tests according to this European Standard please refer to Annex A and [1]. NOTE Materials with reducing properties can in practice under both oxidising and anoxic (isolated) conditions show completely different leaching behaviour than with the leaching tests specified in prEN 16457. This may seriously hamper the interpretation of the leaching tests specified in the supporting CEN/TR on content and leaching (under development).
