Scope
This standard specifies the testing method for calcium and magnesium in water and wastewater. When the calcium concentration range is 0.3~15mg/l, and the magnesium concentration range is 0.05~.3.5mg/l, this method can be used for testing. If the calcium concentration reaches 1500mg/l , when the magnesium concentration is 350mg/l, it can be tested with a single dilution. If the concentration is higher than this, a series of dilutions are required before testing by this method.
