土壤质量.物理化学分析用样品的预处理

[中文适用范围]： 本国际标准规定了对稳定和不挥发参数进行物理化学分析的土壤样品所需的预处理，并描述了以下五种样品预处理类型：干燥、破碎、筛分、分割和研磨。 如果本国际标准中描述的预处理程序影响测定结果，则不适用。 本国际标准也不适用于测量挥发性化合物的样品。 一般来说，分析方法的国际标准会规定何时需要采用其他程序。 [外文原描述]： ISO 11464:2006 specifies the pretreatments required for soil samples that are to be subjected to physico-chemical analyses of stable and non-volatile parameters and describes the following five types of pretreatment of samples: drying, crushing, sieving, dividing and milling. The pretreatment procedures described in ISO 11464:2006 are not applicable if they affect the results of the determinations to be made. ISO 11464:2006 is also not applicable to samples when volatile compounds are measured. In general, International Standards for analytical methods will state when it is necessary to adopt other procedures.
