Scope
Main technical content: This document specifies the on-site determination method for free chlorine in water. This document is applicable to the on-site determination of free residual chlorine in drinking water. This document is not applicable to the determination of highly turbid or high-color water samples. The detection limit of this method (calculated as Cl2) is 5 μg/L, and the determination range (calculated as Cl2) is 20~2000 μg/L. For water samples with free chlorine levels exceeding the upper limit of the method, it is not recommended to determine them after dilution.
