20、 width and length,4.2.2 Minimum yield strength or Grade, and4.2.3 Requirements for inspection (see Section 9),5. General Requirements5.1 The wire used in the manufacture of welded wire reinforcement shall conform to Specification A1064/A1064M withoptional Supplement S1. . After galvanizing, the weld
21、ed wire shall meet the required mechanical properties of SpecificationA1064/A1064M except for the bend test requirements as prescribed in Table 1 of this specification.5.2 Welded wire reinforcement shall be furnished either in flat sheets, or in rolls, as specified by the purchaser.5.3 The zinc used
22、 for coating shall be any grade that conforms to Specification B6.6. Galvanizing6.1 Mass Weight Thickness of Coating and Test:6.1.1 This specification includes six classes of coating weight mass when the welded wire reinforcement is coated beforefabrication and four coating thickness grades when the
23、 welded wire reinforcement is coated after fabrication. The weight massof zinc coating is based on the measured diameter of the wire when the stripping method is performed and the nominal diameterfor all other methods, and shall conform to the requirements shown in Table 2 or Table 3. Individual res
24、ults not more than 10 %below the minimum values specified in Table 2 or Table 3 are allowed if the average of at least two samples from the same coilare equal to or greater than the minimum, individual results shall be not less than 1.08 oz/ft2 330 g/m2.6.1.1.1 When the product is coated before fabr
25、ication in a continuous coating process, coating weights are given in Table 2 forvarious zinc coating classes.NOTE 2Zinc coated wire produced as “regular coating” shall have the full surface covered with zinc, but there is no specified minimum weight ofcoating.6.1.1.2 When the product is coated afte
26、r fabrication in a hot-dip process, coating thickness are given in Table 3 for various zinccoating grades.TABLE 1 Mandrel Diameters for Test for Adherence of ZincCoating Inch-Pound Units SI UnitsMandrel Diameters of Coating Classes and GradesWire Diameter Regular andClass 1Class 3 or A,4, B, 5, andC

This is to minimize a reaction between the reinforcing steel andf
28、resh portland cement paste. Proprietary chromating solutions of equivalent strength are permitted in place of the generic chemical treatment specified.6.1.2 Magnetic Thickness MeasurementsThe weight mass of the coating may be determined by magnetic thickness gagemeasurements in accordance with Pract
29、ice E376. The thickness measurement is used to calculate the weight mass by multiplyingit by the surface area of coated wire and by the zinc density. Because this form of testing can yield inconsistent and potentiallyunreliable results on smaller sizes of wire, one or more of the following methods s
30、hall be permitted to be used to referee and takeprecedence over the results obtained by magnetic thickness measurements.6.1.2.1 Stripping MethodThe weight mass shall be determined by stripping the coating from the steel wire specimen inaccordance with Section 8 and Test Method A90/A90M.6.1.2.2 Weigh
31、ing Before and After GalvanizingThe weight mass shall be determined by weighing the sample before andafter galvanizing. The difference between the two measurements divided by the surface area of the sample provides the weightmass. The original weighing shall occur after pickling and drying. The seco
32、nd weighing shall occur after cooling to ambienttemperature.6.1.2.3 MicroscopyThe weight mass shall be determined by cross-sectional and optical measurement in accordance withTest Method B487. A cross-section sample of the steel shall be polished and examined with an optical microscope to determinet
33、he coating thickness. The coating weight mass shall be determined by multiplying coating thickness by the surface area of thecoated sample and by the density of zinc.6.1.3 Number of TestsFor determination of the coating weight mass, three random samples shall be tested from each lot. Foreach magneti
34、c thickness measurement sample, five or more measurements shall be made along the length and width of the sampleso as to represent the entire surface of the sample. A total of at least fifteen measurements shall be averaged to obtain the coatingthickness. For the microscopy method, five samples shal
35、l be tested per lot. Each sample shall be measured on four sides and thetotal of twenty measurements shall be averaged to obtain the coating thickness. For the stripping method and the weighing method,three samples per lot shall be measured.NOTE 4Alot shall be as follows: all wire of the same size f
36、urnished to the same steel reinforcing specification that has been galvanized within a singleproduction shift.6.2 Handling:6.2.1 The identification of all reinforcing steel shall be maintained throughout the coating and fabrication process to the pointof shipment.TABLE 2 Minimum Weight Mass of Zinc
