3、 suitable for use in the application of gypsum board.1.2 Details of construction for a specific assembly toachieve the required fire resistance shall be obtained fromreports of fire-resistance tests, engineering evaluations, orlistings from recognized fire testing laboratories.1.3 The values stated
4、in inch-pound units are to be regardedas the standard.1.4 The following precautionary caveat pertains only to thetest method portion, Sections 7 and 8, of this specification: Thisstandard does not purport to address all of the safety concerns,if any, associated with its use. It is the responsibility
5、 of the userof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.2. Referenced Documents2.1 ASTM Standards:2E4 Practices for Force Verification of Testing Machines3. Materials3.1 Steel Wire, used in the manufactu

Before fabrication it shall be suffi-ciently ductile to withstand cold-bending, without fracture,through 180 over a radius not greater than the diameter of thewire (see Section 8).4. Physica
7、l Properties4.1 DuctilityThe nail shall be sufficiently ductile to with-stand cold bending without fracture when tested according toSection 8.4.2 Withdrawal ResistanceThe average withdrawal resis-tance, both immediate and delayed, shall be at least equal tothat provided by 12.5 gage (0.099 6 0.003 i
8、n.) (2.515 6 0.08mm) bright, smooth shank, nails with a medium diamondpoint, when tested according to 8.2.5. Dimensions and Permissible Variations5.1 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 p
9、eripheral edge, shall beuniformly tapered to a small fillet around the shank, shall beeither flat or concave, and shall be free from protrusions 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
10、nails shall have medium to long diamondor needle points.5.4 ClearanceWhere a deformation process producesother than a smooth shank nail, a clearance area (round andsmooth), measured from the top of the head to the deformedsection, shall be provided equal to the nominal thickness of thegypsum board f
11、or which the nails are specified.6. Workmanship, Finish, and Appearance6.1 The nails shall be bright, or chemically treated, orcoated with rust inhibiting material provided that such chemi-cal treatment or rust inhibitor does not adversely affect theperformance of the nail as specified in Section 4.
12、 The nailsshall also be compatible with the joint compound and decora-tion. Nails shall be neatly formed and free from injuriousdefects or deformations.7. Number of Tests7.1 At least five nails from each lot of 100 individualcontainers shall be examined to determine conformance to therequirements of
13、 this specification.8. 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.1This specification is under the jurisdiction of ASTM Committee C11 onGypsum and Related Building Mate

17、.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 determinesthe resistance to withdrawal from a wood block of the test nailcompared to a standard nail. It is used to determine compli
18、ancewith 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 load at the strain rate prescribed in 8.2.3.2.The load platform shall be of sufficient size to accept the blockof wood de
19、scribed 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 toPractices E4, Sections 16 through 18.8.2.2.3 Load Indicating Equipment, capable of reading to 1lbf (4.45 N) increments shall
20、be provided for the test apparatus.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 or lower cross head shall be provided so that the nailsare aligned with the direction of pull.Adevice shall be attachedto th
21、e 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 6 in.
