ASME B107.500-2020 pdf free download.Pliers and Shears.
This Standard provides performance and safety requirements for pliers suitable for cutting wire; for long-nose, long-reach pliers; for hand shears generally used for cutting sheet metal; for wire-twister pliers. which are used primarily for securing safety wires; for pliers suitable for inserting and removing internal and external retaining rings, including those covered by ASME B18.27; for pliers having gripping surfaces and! or cutting edges; for cutters and pliers less than 6 in. long, equipped with a spring, typically used In the manuIacture of electronic equipment; for adjustable joint and slip joint pliers; for locking pliers that are suitable for gripping, clamping, pinching. cutting, and wrenching; for pliers (also known as Cannon Plug Pliers) that are used primarily for connecting or disconnecting threaded lock collars ofelectrical connectors; and forwire strippers, and the cutting and stripping functions of multipurpose tools, for use on solid and stranded copper wire. The tools covered in this Standard are listed by Category number in Sections 6 through 16.
Inclusion of dimensional data in this Standard does not mean that all products described herein are stock production sizes, nor that all production sizes are listed. Consumers should consult with manufacturers concerning lists of stock production sizes.
This Standard also details the purpose, apparatus, procedures, and performance specifications for the functional testing of pliers and shears. It is intended to be used by manufacturers, purchasers, and other persons involved with evaluating these products. Test procedures described herein are used to evaluate conformance to performance requirements,
This Standard may be used as a guide by state authorities or other regulatory bodies in the formulation of laws or regulations. It is also Intended for voluntary use by establishments that manufacture the tools covered.
2 DEFINITIONS
blade pattern: orientation and configuration of the cutting blades.
compound leverage: a system of pivot points that multiply the force applied a the handles and transfer that force to the cutting blades.
convertible: changeable from internal to external setting by disassembly.
copier paper: 20-lb 84-92 GE brightness grain long multipurpose paper or other paper conforming to ASTM D3460.
crusher: parallel flat areas on the inside handle surfaces near the pivot, designed for crushing.
deflection: movement under load.
force: the action of one body on another body that changes. or tends to change, the position or motion of the body acted on.
full length of cut maximum distance cut in one operation. Initial load: a small force applied to the pliers’ handles during the hand load test prior to the major load.
jaw area: the portion of the pliers between the fastener (pivot point) and the cutting or gripping end.
length of cut: the distance cut in one operation.
load: mass or force, depending on use. A load that produces a force due only to gravity may be expressed in mass units. Any other load is expressed in force units.
major loud: the force applied to the pliers’ handles during the handle load test intended to deflect the handles.
moment: a measure of the tendency of a force to rotate a body upon which it acts about an axis.
permanent set: the difference in distance, measured at a right angle to the centerline, between handles before and after application and removal of the major load (also known as plastic deformation).
room temperature: 60°F to 80°F.
scored surface: serrated or crosshatched surface to enhance gripping ability.
shall, should, and may: mandatory requirements of this Standard are characterized by the word shall. If a provision is of an advisory nature, it is indicated by the word should or is stated as a recommendation, If a provision Is of an optional or alternative nature, it is indicated by the word may.
shearing blades: blades that have a single contact point (with each other) that moves from the joint end of the blade to the tip of the blade as handles close.
shroud: device used to limit tip travel on external ring pliers.
universal: changeable from internal to external setting without disassembly.
