BS 7755-3.1:1994 土壤质量 化学方法 重量法测定干物质和水分含量

This International Standard specifies a method for the determination of the dry matter content and water content of soil samples on a mass basis. This method can be applied to all types of soil sam-ples. Different procedures are specified for air-dried soil samples, for example samples pretreated accord-ing to ISO 11464, and for field-moist soil samples. For the determination of soil water content on a vol-ume basis, refer to ISO 11461.

ISO 11465:1993 土壤质量 土壤生物的干物质和水含量的测定 重量法

The method specified can be applied to all types of soil samples. Different procedures are specified for air-dried soil samples, e.g. samples pretreated according to ISO 11464, and for field-moist soil samples. Its principle is drying soil samples to constant mass at 105 鳦 and using the difference in mass of an amount of soil before and after the drying procedure to calculate the dry matter and water contents on a mass basis. For the determination of soil water content on a volume basis, refer to ISO 11461.
