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,

NOTE 1 These soil materials are intended to be sampled according to ISO 22155.

It 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.
