This International Standard describes the preparation of four types of water of different hardness, conductivity and alkalinity, intended to be used for testing the performance of household appliances such as washing machines, dishwashers, tumble dryers, steam irons etc.
It defines the characteristics of these waters and establishes various methods to be used for obtaining them. It also includes specifications for required measurements.
