Description / Abstract:

This document specifies methods for the pretreatment of samples that can be applied "in the field" directly after sampling. Pretreatment methods in this standard are limited to:

— sample division methods aimed at reducing the size/volume of the sample;

— the production of composite samples;

— the selection of a specific fraction of the sampled material.

This document does not apply to biological and microbiological pretreatment.

This document does not apply to soil materials sampled for the content of volatile components. These soil materials should be sampled according to ISO 22155. This document does not give instructions for particle size reduction; guidance should be sought in ISO 11464, ISO 14507 and ISO 23909.

NOTE A further standard, ISO 18400-20X, giving detailed guidance on the sampling of soils for determination of volatile components is to be prepared.
