标准摘要
[中文适用范围]： 本文件规定了两种通过土壤颗粒的质量和体积计算土壤颗粒密度的方法。 第一种方法（4.1）适用于细土（直径小于2毫米），第二种方法（4.2）适用于多孔和非多孔的砾石和石块（直径大于2毫米）。 颗粒密度可用于结合ISO 11272中给出的程序计算土层中固体的比例和孔隙度。 [外文原描述]： ISO 11508:2017 specifies two methods for the determination of particle density of soils calculated from the mass and the volume of soil particles. The first method (4.1) is applicable to fine soil (<2 mm diameter) and the second method (4.2) is applicable to both porous and nonporous gravel and stones (>2 mm diameter). The particle density can be used for the calculation of the proportion of solids and of the porosity of soil layers in combination with the procedure given in ISO 11272.
