Scope

This standard specifies the titration method for free chlorine and total chlorine in water. Special procedures are required for seawater and water containing bromides and iodides. This method can be applied to total chlorine (Cl) concentrations of 0.0004 to 0.07 mmol/l (0.03 to 5 mg/l) and higher concentrations by diluting the sample. For high concentrations exceeding 0.07 mmol/l, JIS K 0400-33-30 (ISO 7393-3) can also be used.
