General Requirements5.1 The wire used in the manufacture of welded wirereinforcement shall conform to either Specifications A82/A82M, A496/A496M,orA1064/A1064M with optionalSupplement S1. After galvanizing, t
19、he welded wire shall meetthe required mechanical properties of either SpecificationsA82/A82M, A496/A496M,orA1064/A1064M, whichever isselected, except for the bend test requirements as prescribed inTable 1 of this specification.NOTE 2Specifications A82/A82M, A185/A185M, A496/A496M, andA497/A497M have
20、 been replaced by Specification A1064/A1064M.5.2 Welded wire reinforcement shall be furnished either inflat sheets, or in rolls, as specified by the purchaser.5.3 The zinc used for coating shall be any grade thatconforms to Specification B6.6. Galvanizing6.1 Mass Weight Thickness of Coating and Test
21、:6.1.1 This specification includes six classes of coatingweight mass when the welded wire reinforcement is coatedbefore fabrication and four coating thickness grades when thewelded wire reinforcement is coated after fabrication. Theweight mass of zinc coating is based on the measureddiameter of the
22、wire when the stripping method is performedand the nominal diameter for all other methods, and shallconform to the requirements shown in Table 2 or Table 3.Individual results not more than 10 % below the minimumvalues specified in Table 2 or Table 3 are allowed if the averageof at least two samples
23、from the same coil are equal to orgreater than the minimum, individual results shall be not lessthan 1.08 oz/ft2330 g/m2.6.1.1.1 When the product is coated before fabrication in acontinuous coating process, coating weights are given in Table2 for various zinc coating classes.NOTE 3Zinc coated wire p
24、roduced as “regular coating” shall have thefull surface covered with zinc, but there is no specified minimum weightof coating.6.1.1.2 When the product is coated after fabrication in ahot-dip process, coating thickness are given in Table 3 forvarious zinc coating grades.NOTE 4At the purchasers reques
25、t the galvanized coating may bechromate treated. This is to minimize a reaction between the reinforcingsteel and fresh portland cement paste. Proprietary chromating solutions ofequivalent strength are permitted in place of the generic chemicaltreatment specified.6.1.2 Magnetic Thickness Measurements
26、The weightmass of the coating may be determined by magnetic thicknessgage measurements in accordance with Practice E376. Thethickness measurement is used to calculate the weight massby multiplying it by the surface area of coated wire and by thezinc density. Because this form of testing can yield in
27、consistentand potentially unreliable results on smaller sizes of wire, oneor more of the following methods shall be permitted to be usedto referee and take precedence over the results obtained bymagnetic thickness measurements.6.1.2.1 Stripping MethodThe weight mass shall be de-termined by stripping
28、 the coating from the steel wire specimenin accordance with Section 8 and Test Method A90/A90M.6.1.2.2 Weighing Before and After GalvanizingTheweight mass shall be determined by weighing the samplebefore and after galvanizing. The difference between the twomeasurements divided by the surface area of
29、 the sampleprovides the weight mass. The original weighing shall occurafter pickling and drying. The second weighing shall occurafter cooling to ambient temperature.6.1.2.3 MicroscopyThe weight mass shall be deter-mined by cross-sectional and optical measurement in accor-dance with Test Method B487.
30、 A cross-section sample of thesteel shall be polished and examined with an optical micro-scope to determine the coating thickness. The coating weightmass shall be determined by multiplying coating thickness bythe surface area of the coated sample and by the density ofzinc.6.1.3 Number of TestsFor de
31、termination of the coatingweight mass, three random samples shall be tested from eachlot. For each magnetic thickness measurement sample, five ormore measurements shall be made along the length and widthof the sample so as to represent the entire surface of thesample. A total of at least fifteen mea
32、surements shall beaveraged to obtain the coating thickness. For the microscopymethod, five samples shall be tested per lot. Each sample shallbe measured on four sides and the total of twenty measure-ments shall be averaged to obtain the coating thickness. For thestripping method and the weighing met
33、hod, three samples perlot shall be measured.TABLE 1 Mandrel Diameters for Test for Adherence of ZincCoating Inch-Pound Units SI UnitsMandrel Diameters of Coating Classes and GradesWire DiameterRegular andClass 1Class 3 or A,4, B, 5, andCGrade 50,60, 65, and80Under0.148 3.701DA3D 3D0.148 3.70to0.500

35、all reinforcing steel shall bemaintained throughout the coating and fabrication process tothe point of shipment.7. Finish and Adherence of Coating7.1 The zinc coating shall have no bare spots. The coatingshall be free of blisters, flux spots or inclusions, dross, and acidor black spots. To ensure la
36、rge continuous length coils, weldsare permitted in the finished wire. A matte gray finish appear-ance shall not be itself a cause for rejection.7.2 Adherence of CoatingThe coated wire as representedby the test specimens shall be capable of passing a bend testwithout cracking or flaking the coating t
37、o such an extent thatany coating is removed when rubbed with the bare fingers. Thebend test specimen shall withstand being bent at room tem-perature through 180 as prescribed in Table 1.8. Number of Tests8.1 Testing for Coating Weight Mass BeforeFabricationFor the purpose of final product testing, o
38、nespecimen from every ten coils of wire or fraction thereof in alot shall be selected at random or a total of seven specimens,whichever is less.8.1.1 A wire sample of sufficient length, approximately 4-ft1.2-m shall be cut from either end of each coil selected fortests described in Section 6.8.2 Tes
39、ting for Coating Thickness After FabricationThepurchaser may specify the sampling and test schedule for thenumber and frequency of tests for coating thickness.8.3 If the number and frequency of test are not specified bythe purchaser:8.3.1 One test specimen from every 20 000 ft21900 m2ofwelded wire r

If the average zinc coating weight mass of the sixsamp
41、les conforms to the specified coating thickness, the lotshall be accepted.9. Inspection9.1 The inspector representing the purchaser shall haveaccess at all times, while work on the contract of the purchaseris being performed, to those areas of the galvanizers plantwhich concern the manufacture of th
42、e material ordered. Thegalvanizer shall afford the inspector all reasonable facilities tosatisfy him that the coating is being furnished in accordancewith this specification.9.2 The material shall be inspected at the galvanizers plantprior to shipment. However, if specified, the purchaser shallcondu

Excep
44、t as otherwise specified in the contract, thecontractor shall have the option to use his own or any othersuitable facilities for the performance of the inspection and testrequirements specified herein, unless disapproved by the pur-chaser at the time of purchase. The purchaser shall have theright to
45、 perform any of the inspections and tests at the samefrequency as set forth in this specification where such inspec-tions are deemed necessary to assure that material conforms toprescribed requirements.10. Rejection and Rehearing10.1 Unless otherwise specified, any rejection shall bereported to the
46、manufacturer within five days from the time ofselection of test specimens.10.2 Welded intersections shall withstand normal shippingand handling without becoming broken, but the presence ofbroken welds, regardless of cause, shall not constitute cause forTABLE 2 Minimum Weight Mass of Zinc Coating, oz
