1SCOPE
This Standard provides performance and safetyrequirements for pliers (also known as Cannon PlugPliers) that are used primarily for connecting or discon-necting threaded lock collars of electrical connectors.Inclusion of dimensional data in this Standard does notmean that all products described herein are stock pro-duction sizes. Consumers should consult with manufac-turers concerning lists of stock production sizes.
This Standard may be used as a guide by state authori-ties or other regulatory bodies in the formulation of laws or regulations.It is also intended for voluntary use byestablishments that use or manufacture the toolscovered.

5 REQUIREMENTS
The illustrations shown herein are descriptive andnonrestrictive, and are not intended 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 strong.durable, and easy to operate. Jaw sleeves or inserts shailbe used to prevent marring of the gripping surface ofcollars. Jaw capacity shall be adjustable through a rangeof 0.75 in.to 2.5 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 per-formance 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 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 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 pro-cedures 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. Hlandles shall have a hardness of 38 to 48 HRC.When comfort grips are furnished, they shall be made
