ASTM E1105-00 pdf free.Standard Test Method for Field Determination of Water Penetration of Installed Exterior Windows, Skylights, Doors, and Curtain Walls by Uniform or Cyclic Static Air Pressure Difference.
This test method covers the determination of the resistance of installed exterior windows, curtain walls, skylights, and doors to water penetration when water is applied to the outdoor face and exposed edges simultaneously with a static air pressure at the outdoor face higher than the pressure at the indoor face.
3. Terminology
3.1 Definitions-For definitions of general terms relating to building construction used in this test method, see Terminology E631.
3.2 Definitions of Terms Specific to This Standard:
3.2.1 specimen, n-the entire assembled unit submitted for test as installed in the exterior wall of a building.
3.2.1.1 Discussion-The test specimen consists of the major components of the assembly, including all joints, cracks, or openings between such components and any panning, recep tors, extenders, sills, mullions, or other parts or components used for assembling any installation. The joints between assemblies and the openings into which they are mounted (masonry openings, for example) are not part of the test specimen. However, these joints may be tested by this procedure.
4. Summary of Test Method
4.1 This test method consists of sealing a chamber to the interior or exterior face of specimen to be tested, supplying air to a chamber mounted on the exterior or exhausting air from a chamber mounted on the interior. at the rate reauired to maintain the test pressure difference across the specimen while spraying water onto the outdoor face of the specimen at the required rate and observing any water penetration.
5. Significance and Use
5.1 This test method is a standard procedure for determining the resistance to water penetration under uniform or cyclic static air pressure differences of installed exterior windows, skylights, curtain walls, and doors.
5.2 Laboratory tests are designed to give an indication of the performance of an assembly Field performance may vary from laboratory performance since the supporting structure for the test specimen, methods of mounting, and sealing in the laboratory can only simulate the actual conditions that will exist in the building. Shipping, handling, installation, acts of subsequent trades, aging, and other environmental conditions all may have an adverse effect upon the performance of the installed product. This field test procedure provides a means for determining the performance of a product once installed in the building.
5.3 The field test may be made at the time the window. skylight, curtain-wall, or door assemblies are initially installed and before the interior of the building is finished. At this time it is generally easier to check the interior surfaces of the assemblies for water penetration and to identify the points of penetration. The major advantage of testing when assemblies are initially installed is that errors in fabrication or installation can be readily discovered and corrections made before the entire wall with its component assemblies is completed at which time the expense of corrective work may be increased many times.
