This document specifies a test method for determining the influence of pH on the leachability of inorganic constituents from a waste material. The equilibrium condition as defined in the document is established by continually adjusting the pH by the addition of acid or base to reach desired pH values. This test method produces eluates, which are subsequently characterized physically and chemically. This document is a parameter specific test as specified in prEN 12920. The application of this test method alone is not sufficient for determining the detailed leaching behaviour of a waste under specified conditions.NOTE This generally requires the application o
