| Significance and Use | ||||||
|
5.1?This test method is a standard procedure for determining the air flow characteristics of various components of the window system under specified air pressure differences at ambient conditions. Note 3:?The air pressure differences acting across a building
envelope vary greatly. The factors affecting air pressure
differences and the implications or the resulting air leakage
relative to the environment within buildings are discussed in the
literature.5.2?Rates of air leakage are sometimes used
for comparison purposes. Such comparisons may not be valid unless
the components being tested and compared are of essentially the
same size, configuration, and design.

|
1.1?This test method is a modified version of Test Method E283/E283M, and provides a standard laboratory procedure for determining air leakage separately through the face and sides of exterior windows, curtain walls, and doors under specified differential pressure conditions across the specimen. The test method described is for tests with constant temperature and humidity across the specimen. Note 1:?Detailing buildings with continuous air barriers
requires that the air barrier plane in a window system be clearly
defined. When special circumstances dictate that the air barrier be
sealed to the window frame at a location other than that used to
seal the specimen to the test chamber in this test method,
additional laboratory testing may be required to clarify potential
paths of air flow through the sides of the window frame. The
adapted testing procedure described herein is intended for this
purpose.
1.2?This laboratory procedure is applicable to exterior windows, curtain walls, and doors and is intended to measure only such leakage associated with the assembly and not the installation. The test method can be adapted for the latter purpose. Note 2:?Performing tests at non-ambient conditions or with a
temperature differential across the specimen may affect the air
leakage rate. This is not addressed by this test method.
1.3?This test method is intended for laboratory use. Persons interested in performing field air leakage tests on installed units should reference Test Method E783. Test Method E783 will not provide the user with a means of determining air flow through the sides of tested specimens. 1.4?Persons using this procedure should be knowledgeable in the areas of fluid mechanics, instrumentation practices, and shall have a general understanding of fenestration products and components. 1.5?The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that 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. |
