18、al Supplement S1 or Specification A496/A496Mwith optional Supplement S1. After galvanizing, the weldedwire shall meet the required mechanical properties of eitherSpecifications A82/A82M or A496/A496M, which ever isselected, except for the bend test requirements as prescribed inTable 1 of this specif
19、ication.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:6.1.1 This specification includes si
20、x 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 wire when the stripping method is per
21、formedand 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 from the same coil are equal to orgre
22、ater 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 2Zinc coated wire produced as “regular coating” shall ha
23、ve 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 3At the purchasers request the galvanized coating may bechroma
24、te 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 MeasurementsThe weightmass of the coating may be
25、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 inconsistentand potentially unreliable
26、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 the coating from the steel wire spec
27、imenin 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 the sampleprovides the weight mass.
28、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. A cross-section sample of thesteel s
29、hall 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 determination of the coatingweight mass
30、, 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 measurements shall beaveraged to obtain
31、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 method, three samples perlot shall be me
32、asured.NOTE 4A lot shall be as follows: all wire of the same size furnishedto the same steel reinforcing specification that has been galvanized withina single production shift.6.2 Handling:6.2.1 The identification of all reinforcing steel shall bemaintained throughout the coating and fabrication pro

The coatingshall be free of blisters, flux spots or inclusions, dross, and acidor black spots. To ensure large continuous length coils, weldsare
35、 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 to such an extent thatany coating is r

If the average zinc coating weight mass of the sixsamples conforms to the specified coating
40、 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 the material ordered. Thegalvanizer sha
41、ll 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 shallconduct the test which govern the acceptan
42、ce or rejection of thematerials in his own laboratory or elsewhere.9.3 For Government Procurement OnlyExcept as other-wise specified in the contract, the contractor is responsible forthe performance of all inspection and test requirements speci-fied herein. Except as otherwise specified in the contr
43、act, 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 perform any of the inspections and t
44、ests 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 manufacturer within five days from th
45、e 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 forrejection unless the number of broken welds per sheet exceeds1 % of the total number
46、 of joints in a sheet, or if the materialis furnished in rolls, 1 % of the total number of joints in 150 ft214 m2 of welded wire reinforcement and, furthermore, pro-vided not more than one half the permissible maximum numberof broken welds are located on any one wire.10.3 RehearingRejected materials
47、 shall be preserved for aperiod of at least two weeks from the date of inspection, duringwhich time the manufacturer shall be permitted to make claimfor a rehearing and retesting.TABLE 2 Minimum Weight Mass of Zinc Coating, oz/ft2g/m2 Coated Before FabricationWire Diameterin. mm1Class 1 Class 2 Clas
