Division 5 Geochemical characteristics and behaviour of the waste

Specification of the chemical and mineralogical characteristics of the waste, and of any additives or residuals remaining in the waste.

Prediction of drainage chemistry over time for each type of waste, taking into account its intended handling, in particular:

• evaluation of metals, oxyanion and salt leachability over time by pH dependence leaching test, and/or percolation test and/or time-dependent release and/or other suitable testing,

• for sulphide-containing waste, static or kinetic tests shall be carried out in order to determine acid-rock drainage and metal leaching over time.
