These factors should be fully considered prior to specifying the test pressure difference to be used. Building Diagnostics Group, Inc. Posted on April 20, by admin.

Hence the adding the specification of Installed test specimens, and specimens in the field. 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. This test method does not address these issues.

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.

Failures during quality assurance new construction testing can result in unnecessary delays that impact your bottom line. 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.

Historical Version s – view previous versions of standard. Included diagrams show these differences. 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. In service, the performance will also depend on adtm rigidity of supporting construction and on the resistance of components to deterioration by various causes, vibration, thermal expansion and contraction, etc.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Categories Click on area of interest below. 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 r331 applied using a calibrated spray apparatus while simultaneously applying uniform static pressure to opposite sides of the test specimen.

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.

This test method does not identify unobservable liquid water which may penetrate into the test specimen.

ASTM E 331

Search Search our news blog. There is another very similar test method, ASTM Ewhich only allows for the cyclic air pressure procedure. This allows us to not only properly test fenestrations on new construction projects, but also pinpoint the cause of any test failures and provide accurate recommendations to achieve successful testing results.


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 r331 on the inside or opposite side of the test specimen.

Some designs are more sensitive than others to this upward moving water. There astj fundamental differences aatm are revealed in the titles of each standard. Water that penetrates the assembly, but does not result astk a failure as defined herein, may have adverse effects on the performance of contained materials such as sealants and insulating or laminated glass. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.

In short, the is easier to comply with in the field. The testing pressure differential is usually determined by the testing 3e31. Your email address will not be published. Give us a call to discuss your next project. Most generic specifications call for a minimum testing pressure of 6.
