based on specific design pressures (DP). ▫ Water penetration resistance (ASTM E and ASTM E). ▫ Uniform load deflection test (ASTM. ASTM International E Standard Test Method for Water Penetration of Exterior Windows, Skylights, Doors, and Curtain Wall by Cyclic Static Air Pressure.

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. 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.
Historical Version s – view previous versions of standard. For a negative pressure system, the water-spray grid would be located outside the chamber and the air supply would be replaced by an air-exhaust system.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. These methods are often used both for determining the cause of existing building air leakage atsm for confirming the adequacy of newly constructed wall designs.

This test method does not address these issues. See the illustration below. We also looked at how sealants and adhesives provide air leakage resistance and how the air leakage is related to water ingress as well. 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.

For specific hazard statements, see 7. To watch a three minute video for an AAMA BDG has extensive knowledge of most building systems and specializes in forensic water intrusion investigations.
Our field consultants are properly trained and knowledgeable of all testing standards. It is the responsibility of the user of this standard to establish appropriate asmt and health practices and determine the applicability of regulatory limitations prior to use.
ASTM E 547
In no case shall there be less than two test cycles, and no cycle shall be less than 5 minutes in duration. See the summary for E in this link: 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. Some designs are more sensitive than others to this upward moving water. The air-pressure differences acting across a building envelope vary greatly.
Failures during quality assurance new construction testing can result in unnecessary delays that impact your atsm line. 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.
The list below shows what we have discussed so far and the next steps. For specific hazard statements, see 7. 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.
Link to Active This link will always route to the current Active version of the standard. The testing pressure differential is usually determined by the testing specifier.
The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard. 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 asttm rate of 3.
ashm Professional services based on accurate information that helps you or your company make the right decision regarding your project or asset. The calibrated spray apparatus spray-rack system delivers water to the test specimen at a rate of 5. These factors should be fully considered prior to specifying the test pressure difference to be used.
ASTM E 547-16
MISSION Professional services based on accurate information that helps you or your company make the right decision regarding your project or asset. Most generic specifications call for a minimum testing pressure of 6. BDG utilizes professional testing equipment that is calibrated to each aatm testing standard for accurate results.
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.
