This International Standard specifies a method for the measurement of the electrical conductivity of all types of water.
Electrical conductivity can be used to monitor the quality of
a) surface waters;
b) process waters in water supply and treatment plants;
c) waste waters.
The completeness of analysis for ionic constituents[1 t0 3] can be checked using this method.
In some cases absolute values are important, in other cases only relative changes are of concern.
For interferences, see clause 9.
