BS EN 12485:2010 Chemicals used for treatment of water intended for human consumption - Calcium carbonate, high-calcium lime, half-burnt dolomite, magnesium oxide and calcium magnesium carbonate - Test methods
This European Standard specifies the methods used for the chemical analyses and the determination of
physical properties of calcium carbonate, high-calcium lime, half-burnt dolomite, magnesium oxide and
calcium magnesium carbonate used to treat water for human consumption.
This document describes the reference methods and, in certain cases, an alternative method which can be
considered to be equivalent. In the case of a dispute, only the reference methods are used.
Any other methods may be used provided they are calibrated, either against the reference methods or against
internationally accepted reference materials, in order to demonstrate their equivalence.
