Designation A111 − 99a Reapproved 2014Standard Specification forZinc-Coated Galvanized “Iron” Telephone and TelegraphLine Wire1This standard is issued under the fixed designation A111; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers “iron” wire with ClassA, ClassB, and Class C zinc coatings, suitable for use in telephone,telegraph, and signal transmission.1.2 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are for informa-tion only.2.

Terminology3.1 DefinitionsFor definitions of terms used in thisspecification, see Terminology A902.4. Ordering Information4.1 Orders for wire under this specification shall include thefollowing4.1.1 Size in decimal fractions of an inch or millimetre,4.1.2 Grade,4.1.3 Class of zinc coating A, B, or C,4.1.4 Mandrel test for zinc coating as desired, mandrelsNos. 1 to 12 for Class A or as desired, mandrels Nos. 3 to 12for Classes B and C, and4.1.5 ASTM designation and year of issue.NOTE 1ExampleA typical order including the necessary informa-tion to guide the manufacturer, is as follows5000 lb of 0.109-in. Grade BB wire, Class A coating, mandrel No. 3,ASTM Specification A111.5. Zinc for Coating5.1 The zinc used for the coating shall be any grade of zincconforming to Specification B6.6. Base Metal6.1 The base metal shall be made by any commercially-accepted steel-making process of such quality and purity that,when processed and zinc coated, the finished wire will have theproperties prescribed in this specification for its size and grade.7. Joints7.1 The wire shall be furnished in coils of one continuouslength. Welds made prior to the final wire drawing shall bepermitted.8. Sampling8.1 The inspector shall select at random during the visualexamination specified in Section 18, 1 sample coil from every10 coils in the first 100 coils of the lot, and 1 sample coil forevery additional 35 coils but not less than 3 coils from theentire lot. From each coil of galvanized wire thus selected, asample of suitable length shall be taken for the weight ofcoating, the mechanical and the electrical tests as specified inSections 9–14, inclusive.9. Weight of Coating9.1 The weight of zinc coating, in ounces per square foot orgrams per square metre of uncoated wire surface, shall be notless than that specified in Table 1.9.2 Weight of Coating TestThe zinc coating shall be testedfor weight by a stripping test in accordance with Test MethodA90/A90M.10. Adherence of Coating10.1 The zinc coating shall remain adherent when the wireis wrapped at a rate of not more than 15 turns per minute in a1This specification is under the jurisdiction of ASTM Committee A05 onMetallic-Coated Iron and Steel Products and is the direct responsibility of Subcom-mittee A05.12 on Wire Specifications.Current edition approved Nov. 1, 2014.

United States1close helix of at least two turns around a cylindrical mandrel ofthe diameter specified. The mandrel diameter shall be approxi-mately an even multiple of the diameter of the wire tested. Themandrel shall be specified by the number corresponding to thisdiameter ratio. For example, mandrel No. 1 and mandrel No.12 designate mandrel diameters respectively one and twelvetimes the wire diameter.NOTE 2The coatings on all commercially available wire manufac-tured to meet this specification will pass a wrap test on mandrel No. 12.Coatings are available for passing wrap tests on mandrels as small as No.1 for Class A, and No. 3 for Classes B and C. Coatings passing wrap testson mandrels of intermediate sizes may be specified.10.2 The zinc coating shall adhere firmly to the wire andshall be considered as meeting this requirement if, due towrapping about the specified mandrel, it does not flake andnone of the coating can be removed from the wire by rubbingwith the bare fingers. Loosening or detachment during theadhesion test of superficial, small particles of zinc formed bymechanical polishing of the surface of zinc-coated wire shallnot be considered cause for rejection.11. Breaking Strength11.1 The breaking strength of the galvanized wire shall notbe less than that specified in Table 2 when tested in accordancewith Test Methods and Definitions A370.12. Elongation12.1 The elongation of the galvanized wire shall be not lessthan 10 in 10 in. 254 mm when tested in accordance withTest Methods and Definitions A370. The elongation shall bedetermined as the permanent increase in length after failure ofa marked section of the wire originally 10 in. 254 mm inlength.13. Ductility13.1 The base metal of the galvanized wire of each gradeshall not fracture when the wire is wrapped at a rate of notmore than 15 turns per minute in a close helix of at least twoturns around a cylindrical mandrel of a diameter equal to thenominal diameter of the wire tested.14. Resistivity14.1 The weight resistivity of the wire expressed in ohmpound per square mile ohm gram per square metre at 68F20C shall conform to the requirements specified in Table 3.14.2 Resistivity Test The resistivity shall be determined inaccordance with Test Method B193.15. Size and Permissible Variations15.1 SizeThe size of the galvanized wire shall be ex-pressed as the diameter of the wire in decimal fractions of aninch or millimetre.15.2 Permissible VariationsThe permissible variations ofthe galvanized wire from the nominal diameter shall be asfollowsNominal Diameter of Wire, in. mmPermissible Variations, plus or minus,in. mm0.109 2.77 and over0.083 2.110.004 0.100.003 0.0815.3 GagingThe wire of each coil selected for purpose oftest Section 8 shall be gaged in three places; one near eachend of the coil and one approximately at the middle. A coilshall be rejected if the diameter, at any point, is not within thelimits specified in 15.2.16. Workmanship, Finish, and Appearance16.1 The galvanized wire shall be free of splints, scales,inequalities, flaws, and other imperfections not consistent withgood commercial practice. The coating shall be continuous andreasonably uniform.17. Inspection17.1 The manufacturer shall afford the inspector represent-ing the purchaser all reasonable facilities, without charge, tosatisfy him that the material is being furnished in accordancewith this specification. All tests and inspection shall be made atthe place of manufacture, prior to shipment, and shall be soconducted as not to interfere unnecessarily with the operationof the works.18. Rejection18.1 The inspector shall visually examine the entire ship-ment of lot of coils for surface imperfections. If, after visualexamination, more than 3 of the coils in the entire lot arefound defective, the entire lot shall be subject to rejection. Ifmore than 3 of the samples selected in accordance withSection 8 fail to pass any of the tests specified in Sections 9–15, inclusive, the entire lot shall be subject to rejection.

The diameter of the eye ofeach coil shall be not less than 17 in. 432 mm, nor more than24 in. 610 mm.19.2 The weight of wire in each coil shall conform, withina variation of plus or minus 10 , to the nominal valuesspecified in Table 4.19.3 Each coil shall be securely bound in four separateplaces, equally spaced, with at least two wrappings of galva-nized wire not smaller than 0.080 in. 2.0 mm in diameter. Asan alternative, coils may be securely bound in three separateplaces, equally spaced, with a zinc-coated steel strap.
