TS ISO 5742

TS ISO 5742 is a nomenclature standard for pliers and nippers. In the hand-tool field, where tools may look similar but differ in jaw shape, joint arrangement, and cutting or gripping geometry, a shared vocabulary helps separate one tool family from another in catalogues, drawings, procurement documents, and technical communication.

Why the nomenclature matters

Pliers and nippers cover a wide group of hand tools used for gripping, bending, holding, and cutting. Their practical differences often lie in the details: the nose profile, the cutting edge arrangement, the reach of the jaws, or the leverage created by the joint. This standard provides an English and French nomenclature intended to keep those distinctions consistent. In general technical terms, that makes it easier to describe a tool type precisely without confusing the main family with a specific variant.

Scope, examples, and language notes

• The standard gives a nomenclature for pliers and nippers.
• English and French are the official ISO languages used for the terms.
• Equivalent terms are also given in German, Italian, and Spanish, under the responsibility of the relevant national bodies.
• The figures are examples only and are not intended to influence the manufacturer’s design.
• Only the terms given in the official languages can be regarded as ISO terms.

As a general educational context, nomenclature standards support consistency rather than product testing. TS ISO 5742 therefore serves as a terminology reference for describing hand tools clearly and unambiguously, rather than as a design or manufacturing specification.
