5 REQUIREMENTS
The illustrations shown herein are descriptive andnonrestrictiveand arenotintended to preclude the man-ufacture of pliers that otherwise comply with thisStandard.
5.1 Design
Pliers shall be suitable for loosening and tighteningthreaded lock collars of electrical connectors and shallbe properly proportioned in all parts so as to be strongdurable, and easy to operate. Jaw sleeves or inserts shallbe used to prevent marring of the gripping surface ofcollarsJaw capacity shall be adjustable through a rangeof 0.75 into 25 in.
Pliers shall meet the dimensional requirements asshown in Figs. 1 and 2, and shall be capable of passingall tests in para. 6.
5.2 Material
The materials used in the manufacture of the pliersshall be such as to produce pliers conforming to thisStandard.
5.3 Finish
Surfaces shall have a rust preventive treatment andbe essentially free from pits, nodules, burrs, cracks, andother conditions that would adversely affect the performance or safety of 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 manner 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 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 procedures 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
