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.
