Standard Method of Test for Determining Water-Soluble Sulfate Ion Content in Soil
测定土壤中水溶性硫酸盐离子含量的标准试验方法
AASHTO T 290-95(2020)涵盖了土壤中水溶性硫酸盐离子含量的测定。本标准分为两部分。第一部分规定了取样程序,并将样品制备至测试尺寸。第二部分描述了测定土壤中硫酸盐离子含量的两种试验程序。方法的选择取决于硫酸根离子的浓度和所需的准确度。
AASHTO T 290-95 (2020) covers the determination of the water-soluble sulfate ion content in soil. This standard is divided into two parts. The first part specifies the procedure for sampling and preparing the sample to size for testing. The second part delineates two test procedures for the determination of the sulfate ion content in soils. The selection of the method is dependent on the concentration of sulfate ion and the accuracy desired.
