DIN Standards Committee Water Practice

Overview

This document specifies an up-flow percolation test (PT) which is applicable in compliance testing to determine the leaching behaviour of inorganic and non-volatile organic substances from granular solids with potential for use as construction material. The principle is identical to CEN TS 16637-3 "Construction products - Assessment of release of dangerous substances - Part 3: Horizontal up-flow percolation test". Waste materials with no potential for reuse are excluded from the scope of application. The test applies to waste materials whose general long-term leaching behavior is known from previous studies. This document (EN 17516:2023) has been prepared by Technical Committee CEN/TC 444 "Environmental characterization of solid matrices", the secretariat of which is held by NEN (Netherlands). The responsible German standardization committee is Subcommittee NA 119-01-02-05 UA "Elutionsverfahren" ("Leaching methods") of Working Committee NA 119-01-02 AA "Abfall- und Bodenuntersuchung" ("Waste and soil investigation") at DIN Standards Committee Water Practice (NAW).
