Karakterizimi i mbeturinave - Provat e sjelljes në tretje - Ndikimi i pH në tretje nën kontrollin e vazhdueshëm të Ph

Characterization of waste - Leaching behaviour tests - Influence of pH on leaching with continuous pH-control

Scope

This document specifies a test method for the determination of the influence of pH on the leachability of inorganic constituents from a waste material. Equilibrium condition as defined in the document is established by continuous adjustment of the pH by 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 EN 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 EN 12920.
