The most ast, steps in running the E test, once the wall assembly is attached and sealed to the ASTM E test wall, are listed below. In my last blog I listed the steps for the E test and in this blog I have left kept those steps but in bold font for comparison.
Professional services based on accurate information that helps you or your company make the right decision regarding your project or asset.
ASTM E 547
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 methods are often used both for determining the cause of existing building air leakage and for confirming the adequacy of newly constructed wall designs. 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 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 opposite side of the test specimen. We provide testing services throughout the United Ast from our headquarters located in Atlanta, GA. Building Diagnostics Group, Inc. 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.
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 values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.
This allows us to not only properly test fenestrations on wstm construction projects, but also pinpoint the cause of any test failures and provide accurate recommendations to achieve successful astj results.
ASTM E | Water Penetration Testing
The aatm differences acting across a building envelope vary greatly. 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.
Give us a call today for more information asgm to discuss you next project. We also looked at how sealants and adhesives provide air leakage resistance and how the air leakage is related to water ingress as well. 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 water spray system has nozzles spaced on a grid to deliver water so that the test specimen is wet uniformly, including those areas vulnerable to water penetration. The E test, like E, provides the details of the instrumentation similar to ASTM E to create a pressure difference across a multitude of building assemblies during the calibrated water spray minimum rate of 3. These factors should be fully considered prior to specifying the test pressure difference to be used.
See the summary for E in this link: Historical Version s – view previous versions of standard. In my last blog, I focused on a long standing and very useful laboratory test used to measure water penetration: For specific hazard statements, see 7.
BDG has extensive knowledge of most building systems and specializes in forensic water intrusion asgm.
In no case shall e57 be less than two test cycles, and no cycle shall be less than 5 minutes in duration. 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 list below shows what we have discussed so far and the next steps. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.

Link to Active This link will always route to the current Active version of the standard. In recent earlier blogs I reviewed the primary wall types and wstm each created different challenges for adhesives and sealants in preventing water ingress into the wall assembly. Failures during quality assurance new construction testing can result in unnecessary delays that impact your bottom line. Most generic specifications call for a minimum testing pressure of 6.
This test method does not address these issues.
