1、Designation:D6381/D6381M15(Reapproved 2020)Standard 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 rev
2、ision,the year of 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
3、 is appli-cable to shingles that use a factory-applied or field-appliedsealant.1.2 There are several types of shingles designed for servicewithout a factory-applied or field-applied sealant.Theseshingles,when applied in accordance with the manufacturersapplication instructions,employ other means to
4、provide resis-tance against the forces generated by the action of wind such asgeometry and shingle construction.Field experience has shownthat these types of shingles function satisfactorily in service.Because there are a variety of these shingle designs,it is notpractical to describe in this test m
5、ethod how to test 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 dev
6、ice which facilitateslifting of the edge of the shingle and measuring the forcerequired to break the seal.Procedure B employs a metal“T”section adhered to the weather surface of the shingle tofacilitate application and measurement of a perpendicular forceto break the seal.1.4 It is not prohibited to
7、 use this test method over a rangeof sealing time and temperature combinations and testingtemperatures to simulate a variety of actual field use condi-tions.The times and temperatures used shall be stated in thereport.1.5 The values stated in either SI units or inch-pound unitsare to be regarded sep
8、arately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in nonconformancewith the standard.1.6 This standard does not purport to address all of thesafety concerns,if
9、 any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.7 This international standard was developed in accor-dance with internationa
