5 REQUIREMENTS
The illustrations shown herein are desciptive andnonrestrictive, and are not intended to prechude the ruanufacture of pliers that otherwise comply with thisStandard
5.1 Deslgn
Pliers shall be suitable for loosering and tighterinpthreaded ?ock collars of electrical corectors and shallbe properly proportioned in all parts so as to be strongdurable, and easy to operate. Jaw sleeves or irserts shallbe used to prevent marring of the gripping surface ofcollars Jaw capacity shall be adjustable thurough a rangtof 0.75 in. to 2.5 in.
Pliers shall meet the dimersional requiremients asshown in Figs. l and 2, and shall be capable of passingall tests in para. 6.
5.2 Materlal
The materials used in the ruanufacture of the pliersshall be such as to produce pliers conforming to thisStandard.
5.3 Fnish
Surfaces shuall have a rust preventive treatrent ardbe essentially free from pits, nodules, burrs, cracks, andother conditions that would adversely affect the performance or safety af the tool. When provided, coatingsshall be adherent, smooth, continuous, and free fromany conditions that would interfere with their protectivevalue, safety and function.
5.4 Marking
Pliers shall be marked in a plain and permanent mnanner with the manufacturcrs name or with a trademarlof such known character that the source of manufactureand country of origin shall be readily determined. Marking shall be as permanent as the normal life expectancyof the pliers to which it is applied (providing the markedsurface has not been subjected to a fretting or abradingaction) and be capable of withstanding the cleaning procedunes normally experienced during its intended use
5.5 Handles
Handles shall be shaped to provide a comfortablehandgrip, and shall be free from rough edges and sharpcorners. Handles shall have a hardness of 38 to 48 HRCWhen comfort grips are furnished, they shall be made from a material capable of withstanding hard usagewithout deterioratjon, and shali pass the solvent testspecified in para. 6.3, Cornfort grips shall remain permanently attached under normal use of the tool.
WARNING: COMFORT GRIPS ARE NOT INTENDED TOGIVE ANY DEGREE OF PROTECTION AGAINST ELECTRICSHOCKAND SHALLNOTBEUSED ON ORNEAR LIVEELECTRIC CRCUITS.
5.6 law Sleeve/insert
The jaw sleeve/insert shall be made from a polymerof vinyl, nylon, or other durable compositiot with a durometer hardness of 73 to 95 on the Shore “A” scaleper ASTM D 2240, and shall pass the tests per paras.6,3 and 6.5.
5.7 Joint
Pliers shall be joined in a permanent manner throughthe use of a fastener. The joining method shall assureunifomm smooth movement through respective numberof adjustnent positions. The fastener shall have a hard-ness of 25 to 38 HRC, except when case hardened whena maximum hardness equivalent to 60 HRC shall bepermuitted.
