1、Designation:D7158/D7158M20Standard Test Method forWind Resistance of Asphalt Shingles(Uplift Force/UpliftResistance Method)1This standard is issued under the fixed designation D7158/D7158M;the number immediately following the designation indicates theyear of original adoption or,in the case of revis

3、naccordance with the manufacturers instructions and sealedunder defined conditions.Shingle designs that depend oninterlocking or product rigidity to resist the wind cannot beevaluated using this test method.The method calculates theuplift force exerted on the shingle by the action of wind at aspecif
4、ied velocity,and compares that to the mechanical upliftresistance of the shingle.A shingle is determined to be windresistant at a specified basic wind speed when the measureduplift resistance exceeds the calculated uplift force for thatvelocity(3-s gust,ASCE 7).1.2 The values stated in either SI uni
