Abstract - (Show below) - (Hide below)

This part of European Standard specifies 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. The test procedure specified in this Standard produces an eluate which shall subsequently be characterized physically and chemically according to appropriate standard methods.
