Scope
—— The structure was adjusted according to GB/T 1.1-2000 "Guidelines for Standardization Work - Part 1: Structure and Writing Rules for Standards" and GB/T 20001.4-2001 "Rules for Standard Writing - Part 4: Chemical Analysis Methods"; —— The units of measurement were modified in accordance with the requirements of national standards; —— The equivalent concentration was changed to molar concentration (the equivalent concentration is still retained in the oxidation-reduction section); —— The symbol for mass concentration was changed from C to ρ, and the symbol for content was changed from M to m; —— A test method for water conductivity was added; —— The test method for turbidity was revised.
