ASTM D6900-10(2020) - 1.12.2020
 
Significance and Use

5.1?After application to either interior or exterior surfaces, latex paints may be subjected to conditions of high humidity, condensation, or precipitation. This may sometimes lead to a loss of adhesion to the substrate over which they have been applied. This method is a quantitative measure of the adhesion of latex paints to glossy substrates under such conditions.

 
1. Scope

1.1?This test method covers a procedure for measuring by scrubbing the adhesion of latex paints to glossy alkyd enamel substrates after exposure to wet conditions.

1.2?The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.3?This standard does not purport to address all of the safety concerns, if any, associated with its use.
