Specifies the principal dimensions of construction worker' s pincers and the test values in order verify their aptitude to function in conformity with ISO 5744. The general technical requirements are given in ISO 5743. This pincers illustrated in ISO 9242 are only examples and are not intended to affect the manufacturers' design.

Overview

ISO 9242:1988 - "Pliers and nippers - Construction worker’s pincers - Dimensions and test values" specifies the principal dimensions and required test values for mason/construction pincers. The standard defines dimensional ranges and performance checks used to verify that pincers are functionally fit in accordance with the test methods of ISO 5744. Illustrations in ISO 9242 are provided only as examples and are not intended to restrict manufacturers’ design choices.

Key topics and requirements

Scope: Principal dimensions and test values for construction worker’s pincers (pliers and nippers) to confirm functional aptitude.

Types covered: Two main types illustrated (Type A and Type B) with nominal length examples (Type A: ~200–280 mm; Type B: ~200–355 mm).

Dimensional tables: Detailed dimensions given in millimetres for different nominal lengths (jaw geometry, lever-arm distances and related key measures).

Performance tests:

Cutting test - maximum cutting force and test-wire diameter are specified to assess cutting capability.
Bending/flexion test - measures permanent opening (difference after flexion) to verify structural resilience.

Adjustment formulas: The standard provides formulae to adjust the required test forces when a tool’s lever-arm ratio differs from the tabulated examples (so manufacturers and test labs can scale forces appropriately).

Non‑technical requirements: General technical specifications and other requirements are referenced to ISO 5743; test methods are referenced to ISO 5744.

Applications

ISO 9242 is practical for:

Tool manufacturers - to design and dimension construction pincers that meet internationally recognised dimensional and test-value expectations.

Quality and conformity testing laboratories - to perform cutting and bending tests consistent with ISO 5744 and validate results against ISO 9242 requirements.

Procurement and specification writers - to specify acceptable pincers dimensions and performance in tenders, purchase orders and product data sheets.

Safety engineers and site supervisors - to select hand tools with verified mechanical performance for construction and masonry work.
