(Test Method)Standard Test Method for Measurement of Asphalt Shingle Tab Mechanical Uplift Resistance
Standard Test Method for Measurement of Asphalt Shingle Tab Mechanical Uplift Resistance
SCOPE
1.1 This test method covers measuring the tab uplift resistance of asphalt roofing shingles by mechanical means. It is applicable to shingles that use a factory-applied or field-applied adhesive. This test can only be used in laboratories to screen different sealant systems within the same laboratory.
Note 1-There are several types of shingles designed for service without a factory-applied or field-applied adhesive. These shingles, when applied in accordance with the manufacturer's application instructions, employ other means to provide resistance against the forces generated by the action of wind such as tab geometry and shingle construction. Field experience has shown that these types of shingles function satisfactorily in service. Because there are a variety of these shingle designs, it is not practical to describe in this test method how to test these shingles for uplift resistance. The testing of these types of shingles, therefore, goes beyond the scope of this test method.
1.2 This test method shall be permitted to be use over a range of sealing time and temperature combinations and testing temperatures to simulate a variety of actual field use conditions. The times and temperatures used must be stated in the report.
1.3 The values stated in SI units are to be regarded as the standard.
1.4 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.
