Physical Properties4.1 DuctilityThe nail shall be sufficiently ductile to with-stand cold bending without fracture when tested according toSection 8.
8、4.2 Withdrawal ResistanceThe average withdrawalresistance, both immediate and delayed, shall be at least equalto that provided by 12.5 gauge (0.099 6 0.003 in.)(2.515 6 0.08 mm) bright, smooth shank, nails with a mediumdiamond point, when tested according to 8.2.5. Dimensions and Permissible Variati
9、ons5.1 HeadsShall be not less than 0.2375 in. (6.0 mm) andnot more than 0.3875 in. (9.8 mm) in diameter, shall be notmore than164 in. (0.4 mm) thick at the peripheral edge, shall beuniformly tapered to a small fillet around the shank, shall beeither flat or concave, and shall be free from protrusion
10、s andsharp, irregular edges.5.2 ShanksDiameter shall not vary more than 6 0.003 in.(0.08 mm) for shank diameters 0.076 in. (1.93 mm) or larger.5.3 PointsThe nails shall have medium to long diamondor needle points.5.4 ClearanceWhere a deformation process producesother than a smooth shank nail, a clea
11、rance area (round andsmooth), measured from the top of the head to the deformedsection, shall be provided equal to the nominal thickness of thegypsum board for which the nails are specified.6. Workmanship, Finish, and Appearance6.1 The nails shall be bright, or chemically treated, orcoated with rust
12、 inhibiting material provided that such chemi-cal treatment or rust inhibitor does not adversely affect theperformance of the nail as specified in Section 4. The nailsshall also be compatible with the joint compound and decora-tion. Nails shall be neatly formed and free from injuriousdefects or defo
13、rmations.7. Number of Tests7.1 At least five nails from each lot of 100 individualcontainers shall be examined to determine conformance to therequirements of this specification.1This specification is under the jurisdiction of ASTM Committee C11 onGypsum and Related Building Materials and Systems and

16、0, West Conshohocken, PA 19428-2959. United States18. Test Methods8.1 Bend Test:8.1.1 Significance and UseThis test method is performedto determine the ductility of a nail, and used to determinecompliance with this specification.8.1.2 ProcedureHold the test nail in a vise and bend bymeans of a clamp
17、 or similar device attached to the free end ofthe nail through 90 over a radius not greater than the diameterof the nail.8.1.3 Precision and BiasNeither the precision nor the biasof the nail bend test have been determined.8.2 Withdrawal Resistance8.2.1 Significance and UseThis test method determines
18、the resistance to withdrawal from a wood block of the test nailcompared to a standard nail. It is used to determine compliancewith this specification.8.2.2 Apparatus:8.2.2.1 Testing machineThe testing machine shall be ofany type that is of sufficient capacity and that is capable ofapplying a tensile
19、 load at the strain rate prescribed in 8.2.3.2.The load platform shall be of sufficient size to accept the blockof wood described in 8.2.2.5. The testing machine shall bepower operated and shall apply the load continuously andwithout shock.8.2.2.2 The test apparatus shall be verified according toPra
20、ctices E4, Sections 16 through 18.8.2.2.3 Load Indicating Equipment, capable of reading to1 lbf (4.45 N) increments shall be provided for the test appa-ratus. A means shall be provided to indicate the maximum loadattained during the test.8.2.2.4 A means of securing the blocks of wood to theplatform
21、or lower cross head shall be provided so that the nailsare aligned with the direction of pull.Adevice shall be attachedto the upper cross head to grasp the nail head securely and holdit during the test for the purpose of pulling the nail from theblock of wood.8.2.2.5 Wood Nailing BlocksNominal 2 by
22、6 in. (38 by140 mm) Douglas Fir, construction grade, containing at least16 %, but not more than 19 %, free moisture as determined bya suitable moisture meter. Required wood blocks for a testseries shall be cut from a single piece of lumber creating blocksfree of knots.8.2.3 Procedure:8.2.3.1 Alterna
23、tely use twenty of the standard 12.5 gaugenails and twenty of the nails being tested and hammer drive toa depth of78 in. (22.2 mm) into the longitudinal center line ofone edge and one side face of the wood blocks. Space nails3 in. (76 mm) apart. Determine the comparative performanceas follows:8.2.3.
24、2 ImmediateWithdraw alternate samples of eachtype of nail from each face, ten of each nail, at the rate of 0.06in. (1.5 mm)/min.8.2.3.3 DelayedCondition the lumber, into which the nailsare driven, at 50 6 2 % relative humidity and 70 6 5F(21.1 6 3C) to constant weight, after which withdraw theremain

Certification9.1 When specified in the purchase order a producers orsuppliers certification shall be furnished to the purchaser thatthe material is in compliance with this
26、specification.10. Packaging and Package Marking10.1 Unless otherwise specified, nails shall be packaged insubstantial commercial containers of the type, size, and kindcommonly used for the purpose, so constructed as to preservethe contents in good condition and to ensure acceptance andsafe delivery
27、by common or other carriers, at the lowest rate, tothe point of delivery. In addition, the containers shall be somade that the contents can be partially removed withoutdestroying the containers ability to serve as a receptacle forthe remainder of the contents.10.2 Unless otherwise specified, individ
28、ual packages andshipping containers shall be marked with the type and length ofnail and the name of the manufacturer or distributor. Individualpackages shall also be marked with the name of the manufac-turer or distributor and the net mass.11. Keywords11.1 gypsum board; nail; points; shanks; wire he
