(Test Method)Standard Test Method for Wind-Resistance of Asphalt Shingles (Fan-Induced Method)
Standard Test Method for Wind-Resistance of Asphalt Shingles (Fan-Induced Method)
SIGNIFICANCE AND USE
Most asphalt shingles that have demonstrated wind resistance by this test have also performed well in use. Natural wind conditions differ with respect to intensity, duration, and turbulence; these conditions are beyond the means of this test to simulate. The results of this test do not directly correlate to wind speeds experienced in service, and no accommodation is made in this test method for building height, building exposure category, or building importance factor.
Many factors influence the wind resistance of shingles in the field; for example, temperature, time, roof slope, contamination by dirt and debris, and fasteners that are misaligned or under-driven. It is beyond the scope of this test method to address all of these influences. This test method is designed to evaluate the wind resistance of asphalt shingles as described in the scope when representative samples are applied to test panels in accordance with the manufacturer’s instructions and conditioned as specified before testing.
SCOPE
1.1 This test method covers the procedure for evaluating the wind resistance of asphalt shingles that results from the shingle’s rigidity (with or without contribution from sealant) or mechanical interlocking (with or without contribution from sealant) or any combination thereof. The shingles are applied to a test panel in accordance with the manufacturer’s instructions and tested at a 2:12 (17 %) slope, or at the lowest slope permitted by those instructions.
1.2 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.
1.3 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.
