Some designs are more sensitive than others to this upward moving water. Failures during quality assurance new construction testing can result in unnecessary delays that impact your bottom line. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.

Posted on Atsm 20, by admin. Give us a call to discuss your next project. 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 ast, water is applied using a calibrated spray apparatus while simultaneously applying uniform static pressure to opposite sides of the test specimen.

This test method does not address these issues.

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

Differences between ASTM E331 & ASTM E1105

The testing pressure differential is usually determined by the testing specifier. Leave a Reply Cancel reply Your email address will not be published.

These are identified with italics below: It is astmm 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.

Most generic specifications call for a minimum testing pressure of 6. Included diagrams show these differences. Categories Click on area of interest below. Historical Version s – view previous versions of standard. The ASTM E testing is performed by applying water to the exterior of the test specimen while lowering asmt pressure inside by means of an air aetm built on the inside or opposite side of the test specimen.

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. It stands to reason that there is a difference, otherwise why two test methods?

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 astn velocity, and lateral or upward moving air and water.

W331 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 ast, contraction, etc.


In short, the is easier to comply with in the field.

For specific hazard statements, see 7. In applying the results of tests by this test e331, note that the performance of a wall or its components, or both, may be a function of proper installation and adjustment. Water that penetrates the assembly, but does not aetm in a failure as defined atsm, may have adverse effects on the performance of contained materials such as sealants and insulating or laminated glass. BDG has extensive knowledge of most building systems and specializes in forensic water intrusion investigations.

Building Diagnostics Group, Inc. These factors should be fully considered prior to specifying the test pressure difference astk be used.

There is another very similar test method, ASTM Ewhich only allows for the cyclic air pressure procedure. These are identified with italics below:. MISSION Professional services based on accurate information that helps you or your company make the right decision regarding your project or asset. 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 calibrated spray apparatus spray-rack system delivers water to the test specimen at a rate of 5. The air-pressure differences acting across a building envelope vary greatly.
