Meaning and Purpose
5.1 The latex paint may be tested by high humidity, condensation or precipitation after being applied to the inner or outer surface. This can sometimes result in a loss of adhesion to the substrate on which they are applied. The method is a quantitative measurement of adhesion between latex paint and gloss substrate in this case.
