ASME B107.11-2002 pdf – PLERS: DIAGONAL CUPTING AND ENDCUTTING.
5.9.2 Coating. All metal surfaces shall be coated to inhibit rust. Coatings shall be adherent, smooth, and continuous, and free from pits, blisters, nodules, and any other conditions that would interfere with their protective value and serviceability.
Pliers shall be marked in a plain and permanent manner with the manufacturer’s name or with a trademark of such known character that the source of manufacture and country of origin shall be readily determined. Marking shall be as permanent as the normal life expectancy of the pliers to which it is applied (providing the marked surface has not then been subjected to a fretting or abrading action) and be capable of withstanding the deaning normally experienced during its intended use.
6 TEST PROCEDURES
WARNING: MANY TESTS REQUIRED HEREIN ARE INHERENTLY HAZARDOUS AND ADEQUATE SAFEGUARDS FOR
PERSONNEL AND PROPERTY SHALL BE EMPLOYED IN
CONDUCTING SUCH TESTS.
6.2 Cut Tests
Cut tests shall be performed per para. 5.2 of ASME 8107.25M. Wire diameter and handle load are shown in Table 2 herein.
6.2.1 Steel Wire. Steel wire for cut tests shall be uncoated single-stranded having minimum tensile strength of 180,000 psi (1 240 MPa) for Style A; 90,000 psi (620 MPa) for Style B; and 70,000 psi (400 MPa) for Style C. Wire being cut may be loosely supported at the jaws by the operator in the manner ordinarily employed.
6.2.2 Steel Wire Cut Test for Types I, U, and In. Three
cuts shall be made at the joint end of the cutting edges, and the load required to completely sever the wire shall not exceed the maximum handle load. Load shall be applied at the point of maximum handle curvature (normal gripping position).
6.2.3 SteeL Wire Cut Test for Type IV. A total of nine cuts shall be made. Three cuts shall made at the approximate midpoint of the cutting edges, and the test load required to completely sever the wire shall not exceed the maximum handle load. Three cuts shall be made at each end of the cutting edges with the wire located not more than 0.13 in. (3.3 mm) from the respective ends. Load shall be applied at the point of maximum handle curvature (normal gripping position). Load determinations shall not be required for cuts made at the ends of the cutting edges.
6.2.4 Paper Cut Test. Following wire cut test, the paper cut test shall be performed per ASME B107.25M, para. 5.2.2. The cutting edges shall completely and cleanly cut bond paper. Load shall be applied at the point of maximum handle curvature (normal gripping position).
6.3 Hardness Test
Harduesses specified herein shall be tested in accordance with ASME B107.25M, para. 5.3. Handle hardness determination shall be taken approximately midway between the fastener and the end of each handle.
6.4 Handle Load Test
Permanent set shall be tested in accordance with para. 5.1 of ASME B1O?.25M. Loads are specified in Table 2 herein. Load shall be applied at the point of maximum handle curvature (normal gripping position). Grips, when provided, shall be removed prior to testing.
6.5 Solvent Resistance Test
Comfort grips and cushion grip throat shall b tested in accordance with para. 5.5.1 of ASME B107.25M.
6.6 Jaw Opening and Closing Test
Pliers shall be tested in accordance with para. 5.4.3 of ASME B107.25M. The load required to open jaws to, or dose jaws from, the respective minimum jaw opening shall not be greater than that shown in Table 3. Jaw opening is specified in Tables 4, 5, 6, or 7.
7 TYPE, CLASS, AND STYLE PROVISIONS
7.1 Type I, Diagonal Cutting, Regular Nose
Pliers shall be suitable for cutting wire close to flat surfaces. One side of the jaws shall be recessed to provide a suitable cutting edge clearance.
7.1.1 Type I, Class 1, Plain, Styles A, B, and C. Pliers shall be similar to Fig. 2 and shall conform to dimensions shown in Table 4 for the size specified.
