ISO 18390:2025

This document specifies a simplified routine method for the dynamic or static sampling, by manual or mechanical means, of cereals, pulses and cereal products to assess their quality and condition.
It is applicable to sampling for the determination of heterogeneously distributed contaminants, undesirable substances and parameters usually homogenously distributed, such as those used to assess quality or compliance with a specification. It is applicable to daily use in the field, and in silos and factories that ship or receive grains.
It does not apply to determining insect infestation in a grain lot. Methods for assessing insect populations are provided in ISO 16002 and ISO 6639-2.
This document does not apply to seeds.
NOTE            The sampling of seeds is governed by the rules established by the International Seed Testing Association (ISTA).
