This standard specifies the determination method of calcium content in boiler water and cooling water. This standard is applicable to the determination of water samples with a calcium content of 10mg/L to 200mg/L in boiler water and cooling water. Water samples with a calcium content exceeding 200mg/L should be diluted before determination.
