本国际标准规定了一种测定活性有氧异养细菌活性的试验方法 土壤中的微生物生物量。本方法适用于土壤质量监测和土壤质量评价 土壤和土壤材料的生态毒性潜力。它也适用于沿污染带取样的土壤 田间坡度，以及在田间或实验室中被实验污染的土壤坡度。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This International Standard specifies a test method for determining the activity of active aerobic, heterotrophic microbial biomass in soils. This method is applicable to the monitoring of soil quality and to the evaluation of the ecotoxic potential of soils and soil materials. It is also applicable for soils sampled along contamination gradients in the field and to soils that are contaminated experimentally in the field or in the laboratory.All current amendments available at time of purchase are included with the purchase of this document.
