Standard Test Method for Measurement of Asphalt Shingle

1.1  This test method covers measuring the uplift resistance of asphalt roofing shingles by mechanical means. It is applicable to shingles that use a factory-applied or field-applied sealant. 1.2  There are several types of shingles designed for service without a factory-applied or field-applied sealant.

Misconceptions of Wind Damage to Asphalt Composition

Dec 28, 2017· Some in the industry refer to ASTM D7158, Standard Test Method for Wind Resistance of Asphalt Shingles Uplift Force/Uplift Resistance Method as a proper and simple method to empirically demonstrate the strength of a shingle after a storm event. In particular, they aim at comparing field-measured strengths to the rating originally determined by the manufacturer.
