Scope

Main technical content: This document specifies the method for determining the total hardness in water by fully automatic potentiometric titration. This document is applicable to the determination of total hardness in source water and domestic drinking water. The minimum detectable concentration of this method is 0.05mg. If the volume of the water sample is 50mL, the minimum detectable concentration (calculated in terms of CaO) of this method is 1.0mg/L.
