Bibliography
Describes a compliance test providing information on leaching of granular wastes and sludges under the experimental conditions specified hereafter, and particularly a liquid to solid ratio of 2 L/kg dry matter in a first step and subsequently of 8 L/kg dry matter in a second step. It applies to waste which has a particle size below 4 mm without or with size reduction (as specified in 4.3.2).
