About this training

Summary

This European Standard specifies the methods used for the chemical analyses and the determination of physical properties of calcium carbonate, high-calcium lime and half-burnt dolomite 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.
NOTE Schematic diagrams of the analyses are given in Annex A (Figures A.1 to A.4).
