ASTM E547 PDF

Dokus The most essential steps in running the E test, once the wall assembly is attached and sealed to the ASTM E test wall, are listed below. 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. This test method does not identify unobservable liquid water which may penetrate into the test specimen. For a negative pressure system, the water-spray grid would be located outside the chamber and the air supply would asmt replaced by an air-exhaust system. The testing axtm differential is usually determined by the testing xstm.

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.

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 calibrated spray apparatus spray-rack system delivers water to the test specimen at a rate of 5.

The testing pressure differential is usually determined by the testing specifier. 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. Our field consultants are properly trained and knowledgeable of all testing standards. BDG has extensive knowledge of most building systems and specializes in forensic water intrusion investigations.

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. Failures during quality assurance new construction testing can result in unnecessary delays that impact your bottom line.

Daisho We also looked at how sealants and adhesives provide air leakage resistance and how the air leakage is related to water ingress as well. 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. Water that penetrates the assembly, but does not result in a failure as defined herein, awtm have adverse effects on the performance of contained materials such as sealants and insulating or laminated glass. ASTM E — 00 The testing pressure differential is usually determined by the testing specifier. 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. 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. 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.

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. The inch-pound equivalents of SI units may be approximate. 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. Significance and Use This test method is a standard procedure for determining the resistance to water penetration under cyclic static air pressure differences.
