33、 a specimen of shinglematerial under defined conditions in a specified test apparatus.The test provides a simple measurement of complex mechani-cal effects which relate to the shingles resistance to wind.8.1.10.2 FastenersVarious fasteners appropriate for appli-cation of shingles shall be permitted
34、in this 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
35、 reported.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 notbe
36、ing parallel 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. Eachspec
37、imen shall 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-
38、tions. If 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 th
39、e cutout 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
40、 specifiedfastening 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
41、a 98 6 3-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 ro
42、w or more 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 shingle
43、s are applied inaccordance with the manufacturers/sellers instructions. If this is the case,it shall be noted in the report since it could affect the result. For normaltesting, the central area of the specimen where the nail penetrates shall betypical of the single thickness exposed area of the shin
44、gle under test. 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
45、prescribed 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.8.1.1
46、0.6 ProcedurePush a 38-mm (112-in.) long galva-nized roofing nail with 9.5-mm (38-in.) diameter head throughthe center of the specimen (entering from the granule side andexiting at the backsurfacing side as in normal shingle applica-tion) such that the head of the nail rests against the granulesurfa
47、ce and the 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
48、 the apparatus shown in Fig. 1into the lower jaws of a constant rate of extension test machinecapable of applying a force of at least 445 N (100 lbf) at anextension rate of 100 mm (4 in.)/min.(2) Place the plate part of the apparatus shown in Fig. 1over the specimen so that the plate is centered ove
49、r thespecimen in contact with the backsurface of the specimen andwith the nail shank protruding through the center of the63.5-mm (212-in.) diameter hole. Use a different nail for eachspecimen to prepare a number of specimens, with nails inposition, ready for conditioning before testing.(3) Place the assembled specimen, nail, and plate into thebase part of the apparatus with the nail pointing upwards sothat it can be gripped by the upper jaw of the test machine. Thearrangement of the assembly ready for test is shown in Fig. 2.(4) C
