Scope

This standard specifies the determination method of calcium and magnesium content in industrial circulating cooling water - atomic absorption spectrometry. This standard is applicable to the determination of calcium content ranging from 0.5 mg/L to 75 mg/L and magnesium content ranging from 0.1 mg/L to 50 mg/L in industrial circulating cooling water. It is also applicable to various industrial water, raw water and domestic water. Determination of calcium and magnesium content in meat. This standard is also applicable to the determination of calcium content in phosphorus-zinc pre-coating solution for industrial circulating cooling water.
