The ASTM E Standard Test Method for Water Penetration of Exterior Windows, Skylights, Doors, and Curtain Walls by Uniform Static Air Pressure Difference is a testing standard that describes the procedures to determine the water penetration resistance of windows, curtain walls, skylights, and doors when water is applied using a calibrated spray apparatus while simultaneously applying uniform static pressure to opposite sides of the test specimen. The ASTM E testing is performed by applying water to the exterior of the test specimen while lowering the pressure inside by means of an air chamber built on the inside or opposite side of the test specimen. The water spray system has nozzles spaced on a grid to deliver water so that the test specimen is wet uniformly, includingthose areas vulnerable to water penetration. The calibrated spray apparatus spray-rack system delivers water to the test specimen at a rate of 5.

For example, a window might leak due to problems with installation of waterproofing and perimeter sealant details, or because of improper materials or methods used by the plant during manufacturing. Many clients come to us for one-day water testing, conducted upon the completion of construction. While such tests are certainly useful and productive, earlier engagement in the process can help contractors and building owners avoid costly, more complex issues frequently uncovered during one-day tests. Water testing determines the resistance of manufactured windows, curtain walls, skylights, and doors to water penetration.
