标准摘要
[中文适用范围]： 本国际标准规定了从大样品制备实验室样品的方法。 根据 ISO 11464 和 ISO 14507，考虑以下分析： - 物理化学参数的测定； ——中度挥发性有机污染物的测定； - 非挥发性污染物的测定。 当必须分析挥发性有机化合物时，本国际标准不适用。 [外文原描述]： ISO 23909:2008 specifies a method for the preparation of laboratory samples from large samples. In accordance with ISO 11464 and ISO 14507, the following analyses are considered: determination of physico-chemical parameters, determination of moderate volatile organic contaminants, and determination of non-volatile contaminants. ISO 23909:2008 is not applicable when volatile organic compounds have to be analysed.
英文名称Soil quality — Preparation of laboratory samples from large samples
