BS EN ISO 11272:2017规定了三种测定土壤干容重的方法 根据土壤样本的质量和体积。这些方法包括干燥和称重土壤样本， 其体积已知[取芯法（见4.1）]或确定[开挖法（见4.2）] 和clod法（见4.4）]。交叉引用:ASTM D1556ASTM D2167ASTM D4914ASTM D5030DIN 18125-2ISO 11508EN 932-1购买本文件时可获得的所有现行修订均包含在购买本文件中。

BS EN ISO 11272:2017 specifies three methods for the determination of dry bulk density of soils calculated from the mass and the volume of a soil sample. The methods involve drying and weighing a soil sample, the volume of which is either known [core method (see 4.1)] or determined [excavation method (see 4.2) and clod method (see 4.4)].Cross References:ASTM D1556ASTM D2167ASTM D4914ASTM D5030DIN 18125-2ISO 11508EN 932-1All current amendments available at time of purchase are included with the purchase of this document.
