Specifies procedures for drying, crushing, sieving, dividing and milling of soil samples prior to chemical analysis.

This Standard specifies the pretreatment of potentially contaminated soil samples required for heavy metal and metalloid analysis. This Standard sets out the procedures for drying, crushing, sieving, subsampling and milling of the samples.NOTES:1 The procedure specified in this Standard requires not less than 500 g of field moist soil.2 This method is not appropriate for some volatile metal/metalloid species which may be subject to evaporative losses during some stages of the sample pretreatment procedure. Furthermore, because of the many and varied situations involved in potentially contaminated sites and their associated soil types, the analyst is required to make decisions as to the most appropriate sample pretreatment sequence for analysis. As a result some changes to the procedure outlined in this method may be necessary; this will depend on the nature of the soil and the objectives of the analytical program.
