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.

Historical Version s – view previous versions of standard. 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.
BDG utilizes professional ast, equipment that is calibrated to each specific testing standard for accurate results. 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. The air-pressure differences acting across a building envelope vary greatly. Blog Building Wall Assemblies: In my last blog, S547 focused on a long standing and very useful laboratory test used to measure water penetration: However, unlike E the E test attempts to simulate more real life exposure by cycling the pressure across the s547 specimen as the test procedure progresses.
In recent earlier blogs I reviewed the primary wall types and how each created different challenges for adhesives and sealants in preventing water ingress into the wall assembly.
MISSION Professional services aztm on accurate information that helps you or your company make the right decision regarding your project or asset. The test-pressure difference or differences at which water penetration is to be determined, unless otherwise specified, shall be Pa 2. Most generic specifications call for a minimum testing pressure of 6.
See the illustration below. The ASTM E Standard Test Method for Water Penetration of Exterior Windows, Skylights, Doors, and Curtain Walls by Cyclic Static Air Pressure Difference is a testing standard of procedures used to determine the water penetration resistance astn windows, curtain walls, skylights, and doors when water is applied using a calibrated spray apparatus while simultaneously applying cyclic static pressure to opposite sides e5447 the test specimen.
These factors should be fully considered prior to specifying the test pressure difference to be used.
Norma ASTM E()
Some designs are more sensitive than others to this upward moving water. Professional services based on accurate information 5e47 helps you or your company make the right decision regarding your project or asset.
Building Diagnostics Group, Inc. 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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Astmm test asfm does not identify unobservable liquid water which may penetrate into the test specimen. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.
ASTM E547 – 00(2016)
Our field consultants are properly trained and knowledgeable of all testing standards. Give us a call today for more information or e5447 discuss you next project.
These factors should be fully considered prior to specifying the test pressure difference to be used. 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 aatm and contraction, etc.
This test method does not address these issues. To watch a three minute video for an AAMA The testing pressure differential is usually determined by the testing specifier. 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.
For a negative pressure system, the water-spray grid would be located outside axtm chamber and the air supply would be replaced by an air-exhaust system.

ASTM E | Water Penetration Testing
For specific hazard statements, see 7. The calibrated spray apparatus spray-rack system delivers water to the test specimen at a rate of 5. For specific hazard statements, see 7. The ASTM Adtm 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.
Some designs are more sensitive than others to this upward moving water.
