Materials6.1 Base MetalThe base metal shall be steel of suchquality and purit

18、y that, when drawn to the size of wirespecified, it shall be of uniform quality and have properties andcharacteristics as prescribed in this specification.6.2 Wire used for the manufacture of strand wire shall meetthe requirements of this specification. The polymer coatingshall be formulated and pro

19、duced properly to conform to therequirements of this specification.6.3 Materials for Barbs:6.3.1 Zinc-Coated Steel Wire, if used for the barbs, shall be14 gage, 0.080 in. (2.03 mm), having a Class 3 zinc coating,minimum 0.70 oz/ft (215 g/m) when tested in accordance withTest Method A 90/A 90M.6.3.2

20、Aluminum Alloy Wire, if used for the barbs, shall be 14gage, 0.080 in. (2.03 mm), Alloy 5000-H38, 6061-T94, orequal, as agreed upon between the manufacturer and thepurchaser at the time of purchase.6.3.3 The choice of either zinc-coated steel wire or alumi-num alloy wire for the barbs shall be that

21、of the manufacturer,unless otherwise specified by the purchaser.7. Manufacture7.1 Class 1 polymer-coated wire shall have the coatingextruded onto the strand wire that conforms to the requirementsas given in Table 1.7.2 Class 2a polymer-coated wire shall have the coatingextruded and adhered to the st

22、rand wire that conforms to therequirements as given in Table 1.7.3 Class 2b polymer-coated wire shall have the coatingfused and adhered to the strand wire that conforms to therequirements as given in Table 1.8. Size and Construction8.1 All barbed wire furnished in accordance with thisspecification s

23、hall be fabricated from two strands of 14 gage,0.080-in. (2.03-mm) metallic-coated core, polymer-coatedsteel wire, with four-point barbs of 14 gage, 0.080-in. zinc-coated steel or aluminum alloy wire.9. Size and Permissible Variations9.1 Line WireThe permissible variation from the nominaldiameter of

24、 the wire shall be 60.004 in. (0.10 mm).9.2 BarbsDue to the mechanics of the manufacture whenforming the barbs, a certain amount of out-of-roundness can beexpected, and this precludes barbs from being subjected tochecks for other than nominal diameter and length. Measuredfrom the center of the two s

25、trand wires, the barb length shall be38in. (9.5 mm), minimum.9.3 Spacing of BarbsBarbs shall be spaced as indicated in4.1.1 or 4.1.2. The individual barb spacing shall be measuredfrom the edge of one barb at the strand to the correspondingedge of the adjacent barb. Cumulative spacing is established

26、bycounting the total number of barbs in a 25-ft (7.6-m) length ofbarbed wire. Barbs are subject to relocation during fabricationand handling; therefore, a rigid interpretation of the spacingrequirement may lead to undue rejections. Any sample with93.5 % of the individual barb spacings conforming to

27、thespecified spacing (634 in. (19 mm) and containing a minimumof 55 barbs (5-in. (127-mm) spacing) or a minimum of 86barbs (3-in. (76-mm) spacing) in 25 ft shall be consideredacceptable.9.4 The length of barbed wire in each spool shall be 80 rods(402 m). This is equivalent to one-quarter mile, or 13

28、20 ft. Atthe option of the manufacturer, 1000-ft (305-m) spools may beoffered.10. Joints and Workmanship10.1 Splicing of individual wires by means of a wrap jointor an electric butt weld is permitted. Not more than threesplices or joints shall exist in any spool of barbed wire. Suchsplices or joints

29、 shall be made in a workmanlike manner.10.2 The strands shall be twisted with a uniform length oflay. The direction of twisting may be either right or left hand.Alternate left and right hand twisting is not permitted.10.3 The barbs shall be sharp, well-formed, wrapped tightly,and spaced in accordanc

30、e with 9.3.11. Weight of Metallic Coating11.1 The minimum weight of zinc coating for the galva-nized barbs shall be 0.70 oz/ft (215 g/m). The minimum weightof the strand wire metallic coating shall conform to Table 1when tested in accordance with Test Method A 90/A 90M orTest Method A 428, as applic

31、able.12. Breaking Strength12.1 The minimum breaking strength of the stranded barbedwire shall be 760 lbf (3380 N) when tested in accordance withTABLE 1 Weight of Strand Wire Metallic CoatingsSpecified CoreDiameter of StrandWire, in.

This breaking strengthvalue reflects that of both strand wires together as one unit.13. Properties of Polymer-Coated Barbed Wir

33、e13.1 The polymer-coated barbed wire shall have a demon-strated ability to conform to the following requirements:13.2 Adhesion Tests:13.2.1 Class 2a shall conform to the requirements of 13.2.2.Class 2b shall conform to the requirements of 13.2.3.13.2.2 Three specimens from each lot shall be tested.M

34、easure a distance of34 in. (19 mm) from the end of thespecimen. With a regular hand grip wire stripper, exert maxi-mum hand pull parallel to the axis of the wire. Attempt toremove the measured portion of the polymer sleeve from thecore wire. The lot shall be acceptable if the polymer sleeve isnot ca

35、pable of being removed from the core wire on all threesamples.13.2.3 Three specimens from each lot shall be tested. Maketwo cuts parallel to the axis of the wire through the coating,approximately116 in. (1.6 mm) apart, at least12 in. (12.7 mm)long. With a knife, peel back a section of the coating be

36、tween18 and14 in. (3.2 and 6.4 mm) long to produce a tab. Attemptto remove the116-in. (1.6 mm) strip of coating by pulling thetab. The lot shall be acceptable if the coating breaks rather thanseparates from the core wire on all three specimens.13.3 Accelerated AgingThe polymer-coated wire shallwiths

37、tand exposure for 1000 h without failure at a black paneltemperature of 145F (63C) when tested in accordance withPractice D 1499. Type D, E, or F apparatus described inPractice G 23 or Type BH apparatus described in Practice G 26shall be used for the test. The product shall be construed tohave faile

38、d the test if one of the following occurs:13.3.1 Shrinkage of the polymer coating is greater than116in./ft (1.6 mm/305 mm) of wire.13.3.2 There shall be no significant change in color or glossof the polymer surface as determined by visual inspection.13.4 ColorUnless otherwise stipulated by the purch

39、aser,the color of the polymer shall be in accordance with thestandard colors contained in Specification F 934: green, olivegreen, brown, and black.14. Thickness of Polymer Coating14.1 The thickness of the polymer coating shall be inaccordance with Table 2.14.2 The thickness of the polymer coating sh

40、all be deter-mined on an individual piece of wire. This specimen may beany length of wire over 12 in. (305 mm).14.3 For Class 1 and Class 2a material, strip the polymercoating mechanically from the wire and measure the minimumand maximum thickness of the polymer coating with a suitablemicrometer.14.

41、4 For Class 2b material, strip the polymer coating bychemical means and determine the diameter of the bare wire.Scrape the coating from one side of the wire and measure thereduced diameter with a micrometer. The thickness of thecoating at this point is the difference between the measurementthus obta

42、ined and the measured diameter of the bare wire. In asimilar manner, determine the thickness of the coating at rightangles to the first determination.14.5 Take care not to remove any of the metallic surfacewhen removing polymer coating by scraping.15. Sampling15.1 For the purpose of the tests, one s

43、pool from every 50spools or fraction thereof in a lot shall be selected at random,or a total of seven samples, whichever is less. A lot shall consistof all of the spools of a single type of barbed wire offered fordelivery at the same time.15.2 Test SpecimensA 4-ft (1.2-m) length of barbed wireshall

44、be cut from the end of the spool for the tests prescribedin Sections 11 through 14. Each strand wire shall be tested forits metallic and polymer coating. The breaking strength valueshall be determined by having the twisted strand tested as acomposite.15.3 Instead of testing wire for its coating and

45、breakingstrength from the completed barbed wire in accordance with15.2, the manufacturer may elect to establish compliance withSections 11 through 14 by tests made on wire prior tofabrication. If the manufacturer makes this election, the pur-chaser still reserves the right to test wire from the comp

46、letedbarbed wire for compliance.15.4 For the purpose of inspection, a maximum of twospools from the lot (as described in 15.1) may be subjected toobservations for barb length and spacing, overall length, andgeneral workmanship.15.5 Instead of inspecting for length by unrolling full spoolsin accordan

47、ce with 15.4, the purchaser and the manufacturermay agree on a weight per spool related to the wire size ormeasuring tools used during manufacturing. The purchaser stillreserves the right to confirm the length by actual measurement.15.6 Inspection for barb spacing is normally performed onthe outer 2

48、5-ft (7.6-m) length of a spool; this permits repack-aging of the spool. Any other selection shall be as agreed uponbetween the manufacturer and the purchaser.16. Retests and Rejection16.1 Should one or more of the individual wire specimensfail the coating tests or a strand specimen fail the breaking

49、strength test, the lot shall be subjected to retest. Four additionalspools of barbed wire for each 50 spools offered shall besampled for retest purposes. The lot size then becomes 50,except that this lot size may vary slightly to accommodatepallet count when the barbed wire is palletized.16.2 Retesting for CoatingShould more than two of theindividual strand wires of the retest specimens fail to meet thespecified coating, the entire lot represented by the retest may berejected.16.3 Retesting for Breaking Strength Should any of theretest specimens fail to meet th
