Scope

This International Standard specifies a method for pretreatment of soil samples by freeze-drying for subsequent analysis. This International Standard is applicable to soil samples for subsequent determination of elements or organic compounds recoginzed as non-volatile under freeze-drying conditions.Generally,this International Standard can also be applied to samples from sludges and sediments. This method is also applicable as a first step for the determination of dry matter(or water)content,for instance in the case of samples with high water content.
