JIS K 0400-33-30:1999 Water quality -- Determination of free chlorine and total chlorine -- Part 3: Iodometric titration method for the determination of total chlorine
This standard specifies the iodine titration method for free chlorine and total chlorine in water. —This method is applicable to the determination of chlorine (Cl) from 0.01 to 0.21 mmol/l (0.71 to 15 mg/l). - Interfering with the stagnation of some substances (see 10.). - Annex B provides for reference the direct determination method for samples with chlorine concentrations exceeding 7 μmol/l (0.5 mg/l).
