Soil quality - Sampling - Part 201 : physical pretreatment in the field
ISO 18400-201:2017 specifies methods for the pretreatment of samples that can be applied "in the field" directly after sampling. Pretreatment methods in this document 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. ISO 18400-201:2017 - does not apply to samples required for biological or microbiological examination, - does not apply to soil materials sampled for the content of volatile components, and NOTE 1 These soil materials are intended to be sampled according to ISO 22155. -? does not give instructions for particle size reduction. NOTE 2 Guidance for particle size reduction is given in ISO 11464, ISO 14507 and ISO 23909.
