GB/T 6367-2012 is a standard for the preparation of known calcium Hardness water in the field of surfactants. The standard specifies the method of preparing known calcium Hardness water in detail, specifies the required reagents, instruments, and specific operation steps and calculation procedures. Through the standardized process, the water that meets the specific calcium Hardness requirements can be precisely prepared. Provide stable and standard test water for surfactant-related performance tests, such as emulsification and dispersion studies under different hard water conditions, to ensure the accuracy and comparability of surfactant performance test results.
