    Abstract - (Show below) - (Hide below)

    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. It applies to waste which has a particle size below 4 mm without or with size reduction (as specified in 4.3.2).
