2.2 Design and construction. The cable cutter shall be the manufacturer's standard commercially available product similar, but not necessarily restricted to the design of the cutter shown in figures 1 and 2. The cable cutter shall consist of a cutting head, handles, and intermediate links between the handles and jaws. The overall length of the cutter shall be 20 1/2 inches, plus or minus 1/2 inch, and the weight shall be no more than 5 pounds, 2 ounces.
2.2.1 Cutting head. The cutting head shall consist of a pair of jaws, two jaw straps, two strap bolts, and a groping hook guide.
2.2.2 Jaws. The jaws shall be fabricated from a commercial grade fine grain tool steel in accordance with the manufacturer's standard practice. The thickness of each jaw shall be not less than 0.300 inches. The difference in thickness of each jaw at any two points shall not exceed 0.004 inches. The difference in the average thickness of the two mating jaws shall not exceed 0.005 inches. Pivotal means shall be provided on the jaws for
equalizing jaw movement and preventing lateral motion of the jaws. The two jaws shall be mounted with no visible sideplay due to excessive clearance between jaws and side bearing surfaces or misalignment of jaw edges. The jaws shall be removable to allow for sharpening of the cutting edges or replacement. Cutting edges of the jaw shall be center cut, similar to figure 1. The bevel hardness of the finished jaws, 0.125 inches from the cutting edges, shall have a Rockwell hardness on the Rockwell C scale of not less than 53 HRC nor greater than 61 HRC, and shall be verified by the test specified in 4.2.2.
2.2.3 Jaw straps. The jaw straps shall be fabricated from a commercial grade carbon steel in accordance with the manufacturer's standard practice. Finished straps shall have a Rockwell hardness on the Rockwell C scale of not less than 43 HRC nor greater than 47 HRC when tested as specified in 4.2.2. The straps shall be either the integral bolt type or the threaded type. When of the integral bolt type, the jaw bolts shall be pressed into one strap and secured to prevent rotation of the bolts and each of the bolts shall be provided with locknuts for securing the jaws. Lock plates, lock washers or other positive means shall be provided to prevent the bolts from becoming loose or rotating. The protruding portion of the bolts shall be held to a minimum to prevent interference in confined areas (see 2.2.5).
2.2.4 Handles. The cutter handles shall be fabricated from a commercial grade carbon steel in accordance with the manufacturer's standard practice. Finished handles shall have a Rockwell hardness on the Rockwell C scale of not less than 43 HRC nor greater than 47 HRC when tested as specified in 4.2.2. When steel tubing is used, the tubing shall be firmly attached to
