The full title of ASTM E explains its purpose: “Standard test method for water penetration of exterior windows, skylights, doors, and curtain. ASTM E Report No.: E Rendered to: IMISON USA. Houston, Texas. PRODUCT TYPE: Foam and Plaster Wall System. SERIES/MODEL. Question: “I have read both ASTM E and ASTM E and can’t find any difference between the two test methods. It stands to reason that.

Your email address will not be published. We provide testing services throughout the United States from our headquarters located in Atlanta, GA. Can you please explain the difference between them? Web Design by Five. BDG has extensive knowledge of most building systems and specializes in forensic water intrusion investigations. It stands to reason that there is a difference, otherwise why two test methods?
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. There is another very similar test method, ASTM Ewhich only allows for the cyclic air pressure procedure.
This test method does not identify unobservable liquid water which may penetrate into the test specimen. Our field consultants are properly trained and knowledgeable of all testing standards. The calibrated spray apparatus spray-rack system delivers water to the test specimen at a rate of 5.
There are fundamental differences that are revealed in the titles of each standard. The testing pressure differential is usually determined by the testing specifier. Some designs are more sensitive than others to this upward moving water.
ASTM E 331
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. If you are looking for a reputable second or third-party testing company to perform accurate professional testing, provide concise reports, and help you through the entire process, contact BDG today.
The ASTM E r331 is performed sstm 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.
It is the responsibility of adtm user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 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.
This test method does not address these issues. Our products are guaranteed to do their job so you’re free to do yours without the hassles and worries of building and maintaining your astn equipment. 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 is applied using qstm calibrated spray apparatus while simultaneously applying uniform static pressure to opposite sides of the test specimen.
Failures during quality assurance new construction testing can result in unnecessary delays that impact your bottom line. Hence the adding the specification of Installed test specimens, and specimens in the field. It is difficult to find these and other differences without actually placing the two standards next each other, page by page. Most generic specifications call for a minimum testing pressure of 6.
BDG utilizes professional testing equipment that is calibrated to each specific testing standard for accurate results. Link to Active This link will always route to the current Active version of the standard. Posted on April 20, by admin. Building Diagnostics Group, Inc.

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. In short, the is easier to comply with in the field. 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. For specific hazard statements, see astk.

Included diagrams show these differences. Professional services based on accurate information that helps you or your company make the right decision regarding your project or asset. 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 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.
These factors should be fully considered prior to specifying the test pressure difference to be used. The air-pressure differences acting across a building envelope vary greatly.

The E describes the test specimen being asfm 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.

It is also interesting to note that there are two AAMA standards that refer to these ASTM standards for most of their atsm and are performed in nearly identical fashion.
