GB/T 21855-2008 Specifies pH-related hydrolysis tests for chemicals. For various chemicals, the standard specifies different pH conditions and Sample Handling methods. By simulating different acid alkalinity environments, observe the hydrolysis reaction process of chemicals, and determine hydrolysis products and related parameters. Detailed test procedures, data recording and analysis methods are specified to accurately evaluate the hydrolysis characteristics of chemicals at different pH levels. This helps to understand the stability and degradation of chemicals in the environment, providing key reference for chemical security evaluation, environment risk prediction and production applications in related industries.
