ISO 11464:2006 PDF

Scope: This International Standard specifies the pretreatments required for soil samples that are to be subjected to physico-chemical analyses of stable and non-volatile parameters and describes the following five types of pretreatment of samples: drying, crushing, sieving, dividing and milling. The pretreatment procedures described in this International Standard are not applicable if they affect the results of the determinations to be made. This International Standard is also not applicable to samples when volatile compounds are measured. In general, International Standards for analytical methods will state when it is necessary to adopt other procedures.
