The calibrated spray apparatus spray-rack system delivers water to the test specimen at a rate of 5. Some designs are more sensitive than others to this upward moving water.

ASTM E | Water Penetration Testing

This test method does not address these issues. BDG utilizes professional testing equipment that is calibrated to each specific testing standard for accurate results. Water that penetrates the assembly, but does not result in a failure as defined herein, may have adverse effects on the performance of contained materials such as sealants and insulating or laminated glass.

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.

e3311 It is difficult to simulate the identical complex wetting conditions that can be encountered in service, with large wind-blown water drops, increasing water drop impact pressures with increasing wind velocity, and lateral or upward moving air and water. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.


Most generic specifications call for a minimum testing pressure of 6.

The air-pressure differences acting across a building envelope vary greatly. Included diagrams show these differences. We provide testing services throughout the United States from our headquarters located in Xstm, GA. These factors should be fully considered prior to specifying the test pressure difference to be used. Posted on April 20, by admin.

ASTM E 331

In service, the performance will also depend on the rigidity of supporting construction and on the resistance of components to deterioration by various causes, vibration, thermal expansion and contraction, etc.

There is another very similar test method, ASTM Ewhich only allows for the cyclic air pressure procedure. The testing pressure differential is usually determined by the testing specifier.

The E describes the test specimen being affixed to the air chamber The E describes the air chamber being affixed to the test specimen Hence the adding the specification of Installed test specimens, and specimens in the field. 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.
