5.5.2 Permanent Set.Permanent set of the handlesfor all types, except Type II, shall not exceed 0.04 in. (1.0mm) when subjected to the handle load test specifiedin para.6.4.Handles contacting each other during loadtesting shall constitute failure.
5.5.3 Comfort Grips. When comfort grips are fur-nished on handles, they shall be made of rubber, plastic,or other suitable material capable of withstanding nor-mal use without deteriorating or rubbing off and shallpass the solvent resistance test specified in para. 6.5.Comfort grips shall remain permanently attached undernormal use.
WARNING:COMFORT GRIPS ON HANDLES ARE NOTINTENDED To GIVE ANY DEGREE OF PROTECTIONAGAINST ELECTRIC SHOCK AND SHALL NOT BE USEDON OR NEAR LIVE ELECTRIC CIRCUITS.
5.6 Joint
5.6.1 Construction. When pliers are opened or closed,there shall be no excessive sideways movement, play,or other indication of looseness that will affect theirfunction.
5.6.2 Fastener Hardness. The fastener hardness shallbe from 25 HRC to 50 HRC except when the fastenerreceives a case hardening treatment in addition to thethrough hardening, a maximum hardness equivalent to60 HRC shall be permitted.
5.7 Jaws
5.7.1 Jaw Opening. Jaw opening shall be measuredat tip of the jaws. Jaws shall open in a smooth and uniform manner to the respective minimum jaw opening as specified in applicable tables for individual type and class of pliers using the procedure specified in para. 6.6. Beyond minimum opening, jaws may open with increasing loads until the positive stop of the tool is engaged. 5.7.2 Cutting Edge Hardness. Cutting edges shall have a hardness from 55 HRC to 65 HRC or equivalent. The balance of the jaw area shall have a minimum hard- ness of 35 HRC.
5.7.3 Cushion Grip Throat. Type I Class 3 pliers shali grip and retain cut wire end. The cushion grip throat shall be made of rubber, plastic, or other suitable mate- rial capable of withstanding normal use without deterio- rating or rubbing off and shall pass the solvent resistance test specified in para. 6.5. Cushion grip throat shall remain permanently attached under normal use.
5.8 Springs When a spring (or springs) is furnished, it shall be captive, durable, and capable of opening the jaws under normal use. The spring shall open the jaws to minimum jaw opening as specified in the applicable tables.
5.9 Finish
5.9.1 Appearance. Pliers shall have finished surfaces as indicated in Fig. 1. These surfaces shall have a maxi- mum surface roughness of 63 kin. (1.6 km), arithmetic average. Measurement of the finish shall be made with an instrument using a cutoff length of 0.03 in. (0.8 m) (refer to ACME B46.1). All other surfaces shall be free of pits, burrs, cracks, and other conditions that may adversely affect the performance or appearance of thepliers.
5.9.2 Coating.All metal surfaces shall be coated toinhibit rust. Coatings shall be adherent,smooth,andcontinuous,and free from pits,blisters, nodules, and
any other conditions that would interfere with their pro-tective value and serviceability.
5.10 Marking
Pliers shall be marked in a plain and permanent man-ner with the manufacturer’s name or with a trademarkof such known character that the source of manufactureand country of origin shall be readily determined. Mark-ing shall be as permanent as the normal life expectancy
of the pliers to which it is applied (providing the markedsurface has not then been subjected to a fretting or abrading action) and be capable of withstanding the cleaningnormally experienced during its intended use.
6 TEST PROCEDURES
6.1 Safety
WARNING: MANY TESTS REQUIRED HEREIN ARE INHER-ENTLY HAZARDOUS AND ADEQUATE SAFEGUARDS FORPERSONNEL AND PROPERTY SHALL BE EMPLOYED INcONDUCTING SUCH TESTs.
6.2 Cut Tests
Cut tests shall be performed per para.5.2 of ASMEB107.25M. Wire diameter and handle load are shown inTable 2 herein.
6.2.1 Steel Wire. Steel wire for cut tests shall beuncoated single-stranded having minimum tensilestrength 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.
