(Test Method)Standard Test Method for Rate of Air Leakage Through Exterior Metal Roof Panel Systems
Standard Test Method for Rate of Air Leakage Through Exterior Metal Roof Panel Systems
SIGNIFICANCE AND USE
This test method is a standard procedure for determining air leakage characteristics under specified air pressure differences.
Note 1—The air pressure differences acting across a building envelope vary greatly. The slope of the roof and other factors affecting air pressure differences and the implications of the resulting air leakage relative to the environment within buildings are discussed in the literature. , , These factors shall be considered fully when specifying the test pressure difference to be used.
Note 2—When applying the results of tests by this test method, note that the performance of a roof or its components, or both, may be a function of proper installation and adjustment. The performance in service will also depend on the rigidity of supporting construction, the presence of interior treatments, the roof slope, and the resistance of components to deterioration by various causes: corrosive atmospheres, aging, ice, vibration, thermal expansion, and contraction, etc. It is difficult to simulate the identical complex environmental conditions that can be encountered in service, including rapidly changing pressures due to wind gusting. Some designs are more sensitive than others to these environmental conditions.
Rates of air leakage are sometimes used for comparison purposes. The comparisons are not always valid unless the components being tested and compared are of essentially the same size, configuration, and design.
Note 3—The specimen construction discussed in 1.2 and required in 8.1 isolates a source of leakage. The rate of air leakage measured during the test method has units of cubic feet per minute per square foot (litres per second per square metre). Openings and details such as end laps or roof curbs are excluded since leakage is measured more appropriately in cubic feet per minute per foot (litres per second per metre) at these conditions. The test specimen area is relatively small; the inclusion of details will give unrealistic imp...
SCOPE
1.1 This test method covers the determination of the resistance of exterior metal roof panel systems to air infiltration resulting from either positive or negative air pressure differences. The test method described is for tests with constant temperature and humidity across the specimen. This test method is a specialized adaption of Test Method E283.
1.2 This test method is applicable to any roof area. This test method is intended to measure only the air leakage associated with the field of the roof, including the panel side laps and structural connections; it does not include leakage at the openings or perimeter or any other details.
1.3 The proper use of this test method requires knowledge of the principles of air flow and pressure measurements.
1.4 The text of this test method references notes and footnotes excluding tables and figures, which provide explanatory material. These notes and footnotes shall not be considered to be requirements of the test method.
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI 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 and health practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements, see Section 7.
