This standard specifies a method for the determination of pH value in aqueous solutions of inorganic chemical products using potentiometry. It is applicable to samples with a pH value range between 1 and 12. The standard covers the principle of determination, reagents, instruments and equipment, operation steps, and safety tips. By calibrating the pH Meter using a standard buffer solution and using a composite electrode measurement of the pH value of the solution, the standard provides scientific guidance for the pH determination of inorganic chemical products.
