ISO 24333:2009规定了通过手工或机械手段对谷物和谷物产品进行动态或静态取样的要求，以评估其质量和状况。 它适用于测定异质分布的污染物，不合需要的物质和通常均匀分布的参数，如用于评估质量或符合规范的那些。 它可以用于确定粮食中的昆虫。 它适用于评估许多转基因生物（GMO）的质量和状况的抽样，但不适合确定非转基因产品中不定期转基因物质的存在。 不适用于种籽

ISO 24333:2009 specifies requirements for the dynamic or static sampling, by manual or mechanical means, of cereals and cereal products, for assessment of their quality and condition. It is applicable to sampling for the determination of heterogeneously distributed contaminants, undesirable substances, and parameters usually homogeneously distributed like those used to assess quality or compliance with specification. It can be used to determine insects in a grain lot. It is applicable to sampling for assessment of the quality and condition of lots of genetically modified organisms (GMO) but is inappropriate for the determination of the presence of adventitious genetically modified material in non-GM product. It is not applicable to seed grain.
