Scope1.1 This test method covers measuring the uplift resistanceof asphalt roofing shingles by mechanical means. It is ap
3、pli-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 pro
4、vide 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 me
5、thod 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
6、device 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 prohibit
7、ed to 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 regard
8、ed separately 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 non-conformancewith the standard.1.6 This standard does not purport to address all of thesafety
9、concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

Significance and Use5.1 Uplift resistance is one of the properties of an appliedshingle that relates to its ability to withstand wind forces. Themechanical tests described are laboratory methods to measurethat resistance at a designat
18、ed temperature after the shingleshave been sealed under designated conditions.5.1.1 This test method determines the mechanical upliftresistance of sealed shingles by direct measurement in aprescribed manner. See Test Method D7158 for the relationshipbetween this mechanical uplift resistance and the
19、uplift forcesderived from the action of wind.5.2 Many factors influence the sealing characteristics ofshingles in the field; for example, temperature, time, contami-nation by dirt and debris, roof slope, and interference bymisplaced fasteners. It is not the objective of this test methodto address al
20、l of these influences. This test method is designedto determine the mechanical uplift resistance when represen-tative specimens of shingles are sealed under selected condi-tions prior to testing.5.3 Procedure A produces lower results than Procedure B.Procedure A provides an edge-lift load value and
21、Procedure Bprovides a perpendicular load value. The procedure applicableto a specific product depends on the specific product design,geometry, and rigidity. It is the responsibility of the user of thistest method to determine the appropriate procedure withreference to the specific product and applic
22、ation. It is possiblethat engineering calculations would require both procedures tobe employed, and for both results to be used in the calculationof the resistance of that specific product to the effects of wind.5.4 When using this method in conjunction with TestMethod D7158 to determine the uplift
23、resistance of shingles aspart of the determination of wind resistance of the shingles,determine the appropriate procedure (Procedure A, ProcedureB, or both) in accordance with the discussion, and examples, ofshingle geometry and sealant configuration in Section 12.2 ofTest Method D7158.6.

Specimen Preparation7.1 Samples for testing shall be selected in accordance withthe method specified in the sampling section of Test MethodsD228. The test s
33、hall consist of ten specimens per test condition,as described in the following paragraphs.7.2 Specimens taken from the sample of shingles shall berepresentative of the typical geometry (area), thickness(caliper), and contamination level (back surface particles, andso forth) of the adhesive in the lo

35、pparatus is a concern, an alternate techniqueof attaching to the top of the specimen is not prohibited (see7.7.3).7.4 The sealant present on the specimen to be tested shall beproportionally representative of the sealant present on theshingle when it is installed in the field. For example, if theline

37、 used on the laboratory-prepared specimen,following the manufacturers application instructions.7.5 In Procedure A, a specimen consists of a bottom piece95 by 178 mm 334 by 7 in.; and a top piece 95 by 114 mm334 by 412 in.; both cut from one shingle as shown in Fig. 3afor single-layer shingles or Fig

Whether the sealant is on the topof
43、 the bottom piece, or on the bottom of the top piece, the “A”dimension in Procedure A is determined by measuring thedistance from the leading edge of the sealant to the leadingedge of the top piece when the sample pieces are correctlypositioned (in accordance with 7.7). In the case where thesealant
44、is on the back of the top piece, the bottom piece shallbe cut so that when the top piece is correctly positioned on thebottom piece, the sealant is in contact with the lower shingle inthe same area of the surface it would contact when correctlyinstalled on a roof in accordance with the manufacturers
45、instructions. The critical dimension in Procedure A is thedistance the top piece overlaps the sealant on the bottom piece(denoted A in Figs. 4a and 4b). This dimension shall be equalto the overlap in the specified application.7.7.2 Position the specimens on the tray without overlap-ping or stacking
