This Technical Specification is applicable to determine the influence of pH on the leachability of inorganic
constituents from a waste material. Equilibrium condition as defined in the standard is established by addition of
pre-determined amounts of acid or base to reach desired end pH values. This test method produces eluates, which
are subsequently characterized physically and chemically.
This Technical Specification is a parameter specific test as specified in ENV 12920. The application of this test
method alone is not sufficient for the determination of the detailed leaching behaviour of a waste under specified
conditions.
NOTE This generally requires the application of several test methods, behavioural modelling and model validation as specified
in ENV 12920.
