1、Designation:D6381/D6381M15Standard Test Method forMeasurement of Asphalt Shingle Mechanical UpliftResistance1This standard is issued under the fixed designation D6381/D6381M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of

2、 last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method covers measuring the uplift resistanceof asphalt roofing shingles by mechanical means.It is appli-cable t

5、 theseshingles for uplift resistance.The testing of these types ofshingles,therefore,goes beyond the scope of this test method.1.3 This test method describes two procedures for measur-ing shingle uplift resistance.Procedure A employs a speciallydesigned apparatus with a clamping device which facilit
