2、sion, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method covers the procedure for calculatingthe wind resistance of asphalt shingles when a

The method calculates the upliftforce exerted on the shingle by the action of wind at a specifiedvelocity, and compares that to the mechanical uplift resistanceof the shingle. A shingle is determined to be w

16、classification and the uplift rigidity of the shingle. The calcu-lated uplift force (FT) for each of the possible classifications iscompared to the measured uplift resistance (RT) of the sealedshingle to establish the wind resistance classification of theshingle.5.2 The method involves three steps:5

21、1 The wind resistance of asphalt shingles is directlyrelated to the ability of the sealed shingle to resist the force ofthe wind acting to lift the shingle from the shingle below. Thistest method employs the measured resistance of the shingle tomechanical uplift after sealing under defined condition
22、s, in acalculation which determines whether this resistance exceedsthe calculated force induced by wind passing over the surfaceof the shingle. Natural wind conditions differ with respect tointensity, duration, and turbulence; while these conditions wereconsidered, and safety factors introduced, ext
23、reme naturalvariations are beyond the means of this test method to simulate.6.2 Many factors influence the sealing characteristics ofshingles in the field; for example, temperature, time, roof slope,contamination by dirt and debris, and fasteners that aremisaligned or under driven and interfere with
24、 sealing. It isbeyond the scope of this test method to address all of theseinfluences. The classification determined in this test method isbased on the mechanical uplift resistance determined whenrepresentative samples of shingles are sealed under definedconditions before testing.6.3 The calculation
