7、owing information:3.1.1 Quantity of each size,3.1.2 Wire size, diameter in inches or (millimetres) (Section12), and3.1.3 Weight (Mass), inside diameter, and method of band-ing of coils.4. Zinc for Coating4.1 The slab zinc used for the coating shall be any grade ofzinc conforming to Specification B6.
8、5. Base Metal5.1 The base metal shall be manufactured by any commer-cially accepted steel making practice, and of such quality that,when processed and zinc-coated, the finished wire shall havethe properties prescribed in this specification.6. Joints6.1 The wire shall be furnished in coils of one con
9、tinuouslength. Welds made prior to final wire drawing shall bepermitted.7. Tensile Strength7.1 The zinc-coated wire shall have a tensile strength of notless than 50 000 psi (345 MPa), nor more than 70 000 psi (483MPa). The tensile strength of the zinc-coated wire shall bedetermined in accordance wit
10、h Test Methods E8. The diameterof the wire shall be measured over the zinc coating for thepurpose of calculating the tensile strength.8. Elongation8.1 The zinc-coated wire shall have an elongation of not lessthan 10 % in 10 in. (254 mm) for nominal sizes 0.284 in. (7.21mm) and smaller. Nominal sizes
11、 larger than 0.284 in. shall havean elongation of not less than 9 % in 10 in. The elongation shallbe determined as the permanent increase in length after failureof a marked section of the wire originally 10 in. in length.9. Torsion Test9.1 The zinc-coated wire shall withstand without fracturethe min
12、imum number of turns specified in Table 1. This testshall be done in accordance with Test Method A938 and thenumber of turns to failure shall meet the requirements of Table1.1This specification is under the jurisdiction of ASTM Committee A05 onMetallic-Coated Iron and Steel Products and is the direc

Weight of Coating10.1 The weight of zinc coating, in ounces per square footor (grams per square metre) of uncoated wire surface, shall benot less than that specified in Table 2.10.2 Weight of Coating TestThe zinc coating shall betested for weight by a stripping test in accordance with T
17、estMethods A90/A90M.11. Adherence of Coating11.1 The zinc coating shall remain adherent when the wireis wrapped at a rate of not more than 15 turns per minute in aclose helix of at least 2 turns around a cylindrical mandrel ofthe diameter specified in Table 3. The zinc coating shall beconsidered as
18、meeting this requirement if, when the wire iswrapped about the specified mandrel, the coating does not flakeand none of it can be removed from the wire by rubbing withfingers. Loosening or detachment during the adhesion test ofsuperficial, small particles of zinc formed by mechanicalpolishing of the
19、 surface of zinc-coated wire shall not beconsidered cause for rejection.12. Size and Permissible Variations12.1 SizeThe size of the zinc-coated wires shall be ex-pressed as the diameter of the wire in decimal fractions of aninch or (millimetres).12.2 Permissible VariationsThe permissible variations
20、ofthe zinc-coated wire from the nominal diameter shall be asspecified in Table 4.13. Workmanship, Finish, and Appearance13.1 The surface of the wire shall be free from injuriousscale, flaws, splits, and other imperfections not consistent withgood commercial practice. The coating shall be continuous
21、andreasonably uniform.14. Sampling14.1 The inspector shall select at random one sample coilfrom every 10 coils in the first 100 coils of the lot, and onesample for every additional 35 coils but not less than 3 coilsfrom the entire lot. From each coil of zinc-coated wire thusselected, a sample of sui
22、table length shall be taken for theweight of coating and mechanical tests as specified in Sections711, inclusive.15. Inspection15.1 Unless otherwise specified in the contract or purchaseorder, the manufacturer is responsible for the performance ofall inspection and test requirements specified in thi
23、s standard.Except as otherwise specified in the contract or purchase order,the manufacturer may use his own or any other suitable facilityfor the performance of the inspection and test requirementsunless disapproved by the purchaser at the time the order isplaced. The purchaser shall have the right
24、to perform any of theinspections and tests set forth in this standard when suchinspections and tests are deemed necessary to assure that thematerial conforms to prescribed requirements.16. Rejection16.1 Failure of any of the test specimens to comply with therequirements of this specification shall c
25、onstitute grounds forrejection of the lot represented by the specimen. The lot may bere-submitted for inspection by testing every coil for thecharacteristics in which the specimen failed, and sorting out thedefective coils.17. Packaging17.1 The finished zinc-coated wire shall be furnished incompact
26、coils reasonably symmetrical in shape. The weight,inside diameter, and method of banding of the coils shall beagreed upon between the manufacturer and the purchaser.TABLE 1 Minimum Number of TurnsNominal Wire Diameter, in.

If the t
30、olerances shown are rigidly applied to suchirregularities that are inherent to the product, unjustified rejections of wirethat would actually be satisfactory for use could occur. Therefore, it isintended that these tolerances be used in gaging the uniform areas of thegalvanized wire.Nominal Diameter
