EIFS Resistance to water penetration has traditionally been measured in accordance with ASTM Standard Test Method for Resistance t Water Penetration of Windows, Curtain Walls, and Doors by Uniform Static Air Pressure Difference (E 331). EIMA modeled its standard test method for resistance to water penetration on E 331 with several modifications. This paper discusses the EIMA test method and results.
