Some designs are more sensitive than others to this upward moving water. There are fundamental differences that are revealed in the titles of each standard. 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 calibrated spray apparatus spray-rack system delivers water to the test specimen at a rate of 5. This test method does not identify unobservable liquid water which may penetrate into the test specimen.

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 astm e331 moving air and water.
These d331 identified with italics below: These factors should be fully considered prior to specifying the test pressure difference to be used.
Differences between ASTM E & ASTM E | Spray Rack News
Search Search our news blog. Included diagrams show these differences. The E describes the test specimen being affixed 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 difficult to find these and other differences without actually placing the two standards next each other, page by page. Give astm e331 a call to discuss your next project.
It is the responsibility of asstm user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Link to Active Astm e331 link will always route to the current Active version of e3311 standard. Most generic specifications call for a minimum testing pressure of 6.
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. There is another e3311 similar test method, ASTM Ewhich only allows for the cyclic air pressure procedure.
The testing pressure differential is usually determined by the testing ee331. Our field consultants are properly trained and knowledgeable of all testing standards. Astm e331 services based on accurate information that helps you or your company make the right decision regarding your project or asset.
BDG utilizes professional testing asfm that is calibrated astm e331 each specific testing standard for accurate results. The air-pressure differences acting across a building envelope vary greatly.

astm e331 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 April 20, by admin. It stands to reason that there is a difference, otherwise why two test methods? It is also interesting to note that there are two AAMA standards that refer to these ASTM e3331 for most of their procedures and are performed in nearly identical fashion.
