scope:

This part of ISO 10381 defines the methods that should be applied when sampling soil from stockpiles. This part of ISO 10381 only includes the sampling of the soil material itself, i.e. the solid phase. It applies to the sampling of soil material that is present in a stockpile, generally a heap of soil material that is lying above the surface of the location. The underlying reason for sampling the soil can differ widely as can the subsequent analysis on the obtained samples. This part of ISO 10381 therefore gives guidance on the various aspects that, together, describe the sampling activity: the definition of a sampling plan; the choice of an adequate sampling strategy; the sampling technique to be applied; the sample pretreatment directly after sampling (when necessary); the packing, preservation, storing, transport and delivery of the sample. Given the wide differences in circumstances for all of the above-mentioned sampling steps, this part of ISO 10381 provides information on how to obtain clear and simple instructions for the sampling personnel.
