Scope

This standard specifies the EDTA titration method for the determination of calcium ion content in phosphorus-zinc pre-film solutions of industrial circulating cooling water using polyphosphate and zinc salt as pre-film agents. This standard is applicable to the determination of calcium ion content in the phosphorus-zinc pre-film solution of industrial circulating cooling water between 20 mg/L and 200 mg/L.
