適用范圍:This part of four European Standards specifies a compliance test providing information on leaching of granularwastes and sludges under the experimental conditions specified hereafter, and particularly a liquid to solid ratioof 2 l/kg dry matter. It applies to waste which has a particle size below 4 mm without or with size reduction (asspecified in 4.3.2)This European Standard has been developed to investigate mainly inorganic constituents from wastes. It does nottake into account the particular characteristics of non-polar organic constituents nor the consequences ofmicrobiological processes in organic degradable wastes.The test procedure specified in this European Standard produces an eluate which shall subsequently becharacterised 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 contentratio shall be at least higher than 33%. In addition, the necessary quantity of eluate shall be obtained to perform thephysical and chemical characterisation of the eluate. Furthermore, the minimum dry matter content ratio shall behigh enough to allow a sufficient mixing of the leachant and the test portion.NOTE 1 This procedure cannot be applicable to materials with a water content or such a water affinity that a good mixing ofthe solid with the predetermined quantity of liquid is not achievable.NOTE 2 This procedure cannot be applicable to materials reacting with the leachant, leading, for example, to excessive gasemission, a solidifying effect or an excessive heat release.NOTE 3 By crushing the material, new surfaces are exposed which may lead to a change in leaching properties.NOTE 4 In relation with the minimum dry matter content ratio required for obtaining enough eluate, the test portion specifiedin this European Standard of 175 gram dry matter results in a maximum volume of eluate of 175 ml if its dry matter content ratiois 50 %.When this part 1 is not applicable, the leaching test at L/S = 10 specified in part 2 can be performed.This test cannot be used alone to determine the leaching behaviour of a waste, as specified in ENV 12920.This European Standard does not address issues related to health and safety.
