This test is primarily intended to determine the water resistance of organic coatings by controlled condensation. Condensation is produced by exposing the test surface of the sample to a heated, saturated mixture of air and water vapor, while the reverse side of the sample is cooled to room temperature air. The resulting heat transfer causes the vapor to condense on the test surface. The water temperature is maintained at 120° F (49° C). Effects such as color change, blistering, loss of adhesion, softening, or embrittlement are observed and reported.
