标准范围

ISO 11464:2006规定了对土壤样品进行稳定和非挥发性参数物理化学分析所需的预处理，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ISO 11464:2006中描述的预处理程序影响待测结果，则不适用。ISO 11464:2006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将说明何时需要采用其他程序。

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.
