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
