ASTM E2319-22 - Standard Test Method for Determining Air Flow Through the Face and Sides of Exterior Windows, Curtain Walls, and Doors Under Specified Pressure Differences Across the Specimen
Standard Test Method for Determining Air Flow Through the Face and Sides of Exterior Windows, Curtain Walls, and Doors Under Specified Pressure Differences Across the Specimen
|Keywords:||air leakage; curtain walls; doors; fenestration; laboratory method; static pressure chamber; windows;|
1.1 This test method is a modified version of Test Method , 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 . Test Method 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. For specific hazard statement see Section .
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.
