Optionally co-design standards:
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 (as specified in 4.3.2)
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.
When the first step of this part 3 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.
