ASTM E1105

The ASTM E 1105 - 00 Standard Test Method for Field Determination of Water Penetration of Installed Exterior Windows, Skylights, Doors, and Curtain Wall by Uniform or Cyclic Static Air Pressure is the “go to” standard when field testing newly installed fenestration products.

This testing standard describes the procedures to determine the water penetration resistance of windows, curtain walls, skylights, and doors when wateris applied using a calibrated spray apparatus while simultaneously applying uniform or cyclic static pressure to opposite sides of the test specimen. The ASTM E 1105 is referenced in many other ASTM and AAMA standards including in the ASTM E 331, ASTM E 547, AAMA 502, AAMA 503, and the ASTM E 2128.

The ASTM E 1105 is specifically written for field-testing (installed fenestrations) by using either Procedure A (uniform pressure) or Procedure B (cyclic pressure). The difference between uniform and cyclic is the procedure in which the pressure is applied. Uniform means consistent static pressure is applied of a period of 15 minutes. Cyclic means the static pressure is cycled, 5 minutes on, 1 minute off, for 3 cycles. In no case, shall the total time be less than 15 minutes unless a failure occurs. Procedure B (cyclic) is, in our opinion, the most realistic testing for “real world” conditions.

The ASTM E 1105 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 in such a manner as to wet all of the test specimen uniformly and wet those areas vulnerable to water penetration. The calibrated spray apparatus (spray-rack system) delivers water to the test specimen at a rate of 5.0 U.S. gal/ft²-h. The testing pressure differential is usually determined by the testing specifier. Most generic specifications call for a minimum testing pressure of 6.24 psf.

Building Diagnostics Group, Inc. (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 not only to properly test fenestrations on new construction projects, but if there is a test failure, we can pinpoint the cause of the failure and provide accurate recommendations to achieve successful testing results. Failures during quality assurance (new construction) testing can result in unnecessary delays that can impact your bottom line.
