Example 1: Analysis of base or heating water
A special feature in the field of coolant analysis is the analysis of as yet unmixed, unadditivised base water or heating water.
The evaluation of analysis values mostly takes place based on the specifications of the manufacturer of engines or coolant concentrates.
For water intended for use in heating (not cooling), further guidelines (e.g. VDI 2035) may be used as a basis. In the analysis of base water, the chloride and sulphate content is very important, as well as the pH value and water hardness, as chlorides and sulphates can favour corrosion and reduce the efficacy of corrosion inhibitors.
