Significance and Use | ||
5.1?This test method is a standard procedure for determining the resistance to water penetration under uniform static air pressure differences. The air-pressure differences acting across a building envelope vary greatly. These factors should be fully considered prior to specifying the test pressure difference to be used. Note 1:?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. 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. 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. Some designs are more sensitive than others to this upward
moving water.
Note 2:?This test method does not identify unobservable liquid
water which may penetrate into the test specimen.

1. Scope | ||
1.1?This test method covers the determination of the resistance of exterior windows, curtain walls, skylights, and doors to water penetration when water is applied to the outdoor face and exposed edges simultaneously with a uniform static air pressure at the outdoor face higher than the pressure at the indoor face. 1.2?This test method is applicable to any curtain-wall area or to windows, skylights, or doors alone. 1.3?This test method addresses water penetration through a manufactured assembly. 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. 1.4?The proper use of this test method requires a knowledge of the principles of pressure measurement. 1.5?The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard. 1.6?This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
