GB/T 6367-2012 Surface active agents—Preparation of water with known calcium hardness
Abstract
This standard specifies the preparation method for water with known calcium hardness.
This standard is applicable to the preparation of water with known calcium hardness used in testing surfactants and products containing surfactants.
In many surfactant hard water tests, there is no essential difference between calcium hardness and magnesium hardness, so these tests can usually be conducted in a chloride calcium solution with known calcium hardness.
