MISSION Professional services based on accurate information e331 helps you or your company make the right decision regarding your project or asset. In applying the results of tests by this test method, note that the performance of a wall or its components, or both, may be a function of proper installation and adjustment.


For specific hazard statements, see 7. The testing pressure differential is usually determined by the testing specifier. The air-pressure differences acting across a building envelope vary greatly. Failures during quality assurance new construction testing can result in unnecessary delays that impact your bottom line.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. The water spray system has nozzles spaced on a grid to deliver water so that the test specimen is wet aatm, includingthose areas vulnerable to water asrm. 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.


ASTM E 331

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. It is difficult to find these and other differences without actually placing the two standards next each other, page by page. Can you please explain the difference between them? It is also interesting to note that there are two AAMA standards that refer to these ASTM standards for most of their procedures and are performed in nearly identical fashion.

There is 3e31 very similar test method, ASTM Ewhich only allows for the cyclic air pressure procedure. The E describes the test specimen being affixed to the w331 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.

This test method does not address these issues. These are identified with italics below:. Some designs are more sensitive than others to this upward moving water. The calibrated spray apparatus spray-rack system delivers water to the test specimen at a rate of 5.

BDG utilizes professional testing equipment that is calibrated to each specific testing standard for accurate results.

Included diagrams show these differences. 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.
