7、,-A-A- 1349A 3.3 Materials. The materials used in the manufacturing of the wrenches shall be such as to produce wrenches conforming to the physical requirements hereinafter described. 3.4 Marking. Each wrench shall be marked on one of the faces or on the handle as close to each head as is practicabl
8、e in a plain and permanent manner. In addition to size markings, each wrench shall be marked in a plain and permanent manner with the manufacturers name or trademark of such known character that the source of manufacture may be readily determined. 3.5 Hardness. Wrenches shall be treated to a Rockwel
9、l C hardness not less that 28 nor more than 38 when tested per ASTM-E- 18. 3.6 Wrench Ends. One end shall have a box opening with 12 point (double hexagon). Other end shall terminate with a surface suitable for slugging. 3.7 Wrench Opening. The nut and bolt head-engaging surfaces of the wrench shall
10、 be finished in a smooth and well-defined manner. Wrench opening tolerances shall be such as to insure acceptance when gaged with gages conforming to ASME B 107.17M. 3.8 Finish. 3.8.1 Surface Finish. All surfaces shall be thoroughly cleaned, free from cracks, and essentially free from burrs, pits, n
11、odules, and other detrimental deficiencies. 3.8.2 Coatings. The coating shall be chrome plate (3.8.2.1) phosphate (3.8.2.2), oxide (3.8.2.3), or alternate coating (3.8.2.4) and shall be specified in the contract or order. The coating shall be adherent, smooth, continuous, and free from uncoated area
12、s, pits, blisters, nodules, and any other defects that would interfere with their protective value and serviceability. 3.8.2.1 Chrome Plate. Wrenches shall have a protective-decorative nickel-chromium plating. The nickel thickness shall be a minimum of 0.0001 50 in. The chromium thickness shall be a
13、 minimum of 0.000003 in. A nickel-iron undercoating (1 6% iron max.) may be substituted for nickel. 3.8.2.1.1 Chrome Plate Tests. One measurement of the thickness of each electroplated coating shall be conducted in accordance with any of the following, as appropriate, methods: -1 ASTM B 487: Standar
14、d Method for Measurement of metal and oxide coating thickness by microscopical examination of a cross section. ASTM B 499: Standard Test Method for Measurement of coating thickness by the magnetic method: nonmagnetic coatings of magnetic basis metals. ASTM B 504: Standard Method for Measurement of t
15、hickness of metallic coatings by the coulometric method.
