Characterisation of waste. Leaching. Compliance test for leaching of granular waste materials and sludges. One stage batch test at a liquid to solid ratio of 10 l/kg for materials with particle size below 10 mm (without or with size reduction) (British Standard)
This part of the 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 10 l/kg dry matter. It applies to waste which has a particle size below 10 mm without or with limited size reduction. Note: In some cases, it could be useful to test the material with coarser particles up to 40 mm in diameter: This requires a larger amount for material and liquid.
