Full Description
This part of ISO 8502 describes a field method for the assessment of moisture, usually caused by condensation of water, on steel surfaces prior to application of paint.
The method can be used on flat and slightly curved horizontal and vertical surfaces. The assessment should not be done on surfaces that are exposed to any falling water, e.g. rain, or condensation.
The lowest surface moisture (water) level that can be detected by the method is 4 g/m2. Refinements for considerably lowering this level are indicated in clause 8.
