Full Description

1.1 This test method covers the procedure for testing the wind resistance of asphalt shingles when applied to a test deck on low slopes in accordance with the manufacturer's instructions at the most susceptible slope for wind damage of 2:12 (17 %) permitted by those instructions. It is used to benchmark the blow-off resistance of sealed and interlocked shingles at a given wind velocity, but may be used to test unsealed or sealed shingles at other wind velocities as is applicable.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

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.
