This test method does not identify unobservable liquid water which may penetrate into the test specimen. Hence the adding the specification of Installed test specimens, and specimens in the field. It is the responsibility of the user of this standard to establish e31 safety and health practices and determine the applicability of regulatory limitations prior to use.

We provide testing services throughout the United States from our headquarters located in Atlanta, GA.

It is difficult to find these and other differences without actually placing the two standards next each other, page by page. 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.

The calibrated spray apparatus spray-rack system delivers water to the test specimen at a rate of 5. If you are looking for a reputable second e31 third-party testing company to perform accurate professional testing, provide concise reports, and help you through the entire process, contact BDG today.

Historical Version s – view previous versions of standard. 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.


Categories Click on area of interest below. Most generic specifications call for a minimum testing pressure of 6.

Differences between ASTM E331 & ASTM E1105

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.

BDG has extensive knowledge of most building systems and specializes in forensic water intrusion investigations.

ASTM E 331

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.

Web Design by Five. These factors should be fully considered prior to specifying the test pressure difference to be used. There is another aztm similar test method, ASTM Ewhich only allows for the cyclic air pressure procedure.

This test method does not address these issues. Failures during quality assurance new construction testing can result in unnecessary delays that impact your bottom adtm. Some designs are more sensitive than others to this upward moving water. Our field consultants are properly trained and knowledgeable of all testing standards.

The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard. The testing pressure differential is usually determined by the testing specifier.

MISSION Professional services based on accurate information that helps you or your company make the right decision regarding your project or asset.

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

Differences between ASTM E & ASTM E | Spray Rack News

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. These are identified with italics below: 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 r331 side of the test specimen.

Give us a call to discuss your next project. The air-pressure differences acting across a building envelope vary greatly. Our products are f331 to do their job so you’re free to do yours without the hassles and worries of building and maintaining your own equipment.
