34、test. A standardgalvanized roofing nail with 9.5-mm (38-in.) diameter head isused in the following procedure. The specific fastener usedmust be reported with the results, and if necessary, theorientation of any prominent geometric features with respect tothe shingle orientation shall also be reporte

35、d.NOTE 1When other fasteners, for example, staples, are used with thistest procedure and apparatus, the effects of varying orientation of thestaple crown with the shingle orientation (lengthwise or at some angle tothe length direction of the shingle), or the effects of the staple crown notbeing para

36、llel to the shingle surface, will generally cause greater variabil-ity in the results than when using a roofing nail.8.1.10.3 SpecimensFor single-layer shingles, prepare tenspecimens 98 6 3mm(378 618 in.) square for each sampleor shingle material to be tested at each test condition. Eachspecimen sha

37、ll be composed of a single thickness of shingle.Specimens shall be permitted to include areas containingsealant (factory-applied adhesive) or release tape, or both, ifthis is expected to be in the nailing area when the shingles areapplied in accordance with the manufacturers/sellers instruc-tions. I

38、f this is the case, then note it in the report since it couldaffect the result. For normal testing, the central area of thespecimen where the nail penetrates shall be typical of the singlethickness exposed area of the shingle under test. For shingleswith tab cutouts, any specimen in which the cutout

39、 is visiblethrough the opening in the plate (see 8.1.10.6(2) will have theeffect of increasing the variability of the results.8.1.10.4 For multi-layer shingles, prepare ten specimens 986 3mm(378 618 in.) square using the following procedure.These specimens shall be cut from the manufacturers specifi

40、edfastening position on the shingle. First determine the manufac-turers specific defined fastener placement position on theshingle. This may be found in the written instructions or by adrawing showing the specific fastening points on the shinglewrapper. Once this position is determined, cut a 98 6 3

41、-mm(378 618-in.) wide strip from the shingle with this fasteningposition centered in the strip. Typically, this strip will be cutfrom the long dimension, or length, of the shingle. Use thisstrip to cut consecutive specimens 98 6 3mm(378 618 in.)in length. No less than three specimens in a row or mor

42、e thanfour specimens in a row from one shingle can be used to makeup the ten specimens required for testing.NOTE 2Specimens shall be permitted to include areas containingfactory-applied adhesive (sealant) or release tape, or both, if this isexpected to be in the nailing area when the shingles are ap

43、plied inaccordance with the manufacturers/sellers instructions. If this is the case,it shall be noted in the report since it could affect the result.

Formulti-layered shingles, the test shall be performed in the area specified forfastening in the manufacturers/sellers instructions.8.1.10.5 ConditioningCondition specimens at the tem-peratures prescribed in Table 1 for at least two hours prior totesting, and conduct the test at the prescrib

45、ed temperatures.Other test conditions shall be permitted to give indications offastener pull-through resistance at different temperatures, pro-vided that they specimens are conditioned for at least2handtest at the desired temperature, and that the temperature used isnoted in the report.8.1.10.6 Proc

47、he shank protrudes from the backsurface. It ispermitted to use a fixture to locate the center of the specimenwithin 66mm(614 in.) of the intersection of the diagonals ofthe square specimen or to draw diagonals with chalk tofacilitate central positioning of the nail.(1) Clamp the base part of the app
