7、and Waterproofing3.Summary of Test Method3.1 The force perpendicular to the fastener shank to tear thesheet or to cause fastener failure is measured with the fastenerhead seated and not seated(tear).3.2 The force parallel to the fastener shank to rupture thesheet or to cause fastener failure is meas
8、ured with the headseated(rupture,head pull-through).4.Significance and Use4.1 Test values for the resistance of specific ply sheets,rollroofing,or shingles to selected fastener pull-through may assistin the determination of appropriate fastener spacing.Therelative behavior of different fasteners and
9、 fasteners with andwithout caps may be evaluated.4.2 Laboratory data will not permit prediction of fieldperformance,particularly long-term performance,and if all testconditions are not the same,data may not be comparable.5.Apparatus5.1 Testing MachineUniversal or tensile testing machinewith automati
