Description

This part of four European Standards 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 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. This European Standard has been developed to investigate mainly inorganic constituents from wastes. It does not take into account the particular characteristics of non-polar organic constituents nor the consequences of microbiological processes in organic degradable wastes. The test procedure specified in this European Standard produces eluates which shall subsequently be characterised physically and chemically according to appropriate standard methods. This procedure is only applicable to waste material and sludges having a high solid content : the dry matter content ratio shall be at least higher than 33%. In addition, the necessary quantity of eluate in each step shall be obtained to perform the physical and chemical characterisation of the eluate. Furthermore, the minimum dry matter content ratio shall be high enough to allow a sufficient mixing of the leachant and the test portion.
