Overview
ISO 9343:2021 is an international standard published by the International Organization for Standardization (ISO) that specifies the principal dimensions and test values for slip joint pliers, also known as adjustable pliers with two positions. These pliers are designated as No. 206 under ISO 5742, which covers the nomenclature of pliers and nippers. The standard ensures that slip joint pliers meet stringent quality and functional requirements in alignment with ISO 5744 (test methods) and ISO 5743 (general technical specifications).
The 2021 edition is the third iteration of this standard and introduces important updates such as the introduction of minimum and maximum lengths for each nominal plier size. It aims to provide manufacturers and users with clear guidelines for verifying plier dimensions and testing performance to ensure product reliability and interoperability in professional and consumer tool markets.
Key Topics
Dimensions of Slip Joint Pliers
ISO 9343:2021 defines key measurements including nominal length, jaw width, handle length, and opening width. These dimensions are essential for ensuring that slip joint pliers meet ergonomic and functional prerequisites.Test Values for Quality Assurance
The standard specifies bending test parameters such as the force applied and the maximum permissible permanent deformation of the jaws. These tests verify that the pliers maintain their structural integrity and function under typical working stresses.Designation and Marking
Slip joint pliers are designated by their nominal length and the standard reference (e.g., “206 - ISO 9343 - 180”). The marking requirements comply with ISO 5743, ensuring traceability and conformity marking on the tool itself.Terminology and References
The document aligns with terminology from ISO 5742 and references related standards ISO 5743 (general specifications) and ISO 5744 (methods of testing), reinforcing a consistent framework across hand tool standardization.
Applications
Slip joint pliers covered by ISO 9343:2021 are widely used by mechanics, electricians, plumbers, and general maintenance professionals due to their adjustable jaw opening capability, allowing for gripping and manipulating objects of various sizes. Compliance with this standard ensures tools will provide:
Reliable Performance
Meeting test values guarantees the tool withstands typical operational loads without deformation or failure.Ergonomic Use
Standardized dimensions support user comfort and efficiency in handling.Interchangeability
Uniform sizing and performance make slip joint pliers compatible with other standardized tools and accessories.
Manufacturers benefit from adherence to the standard by validating design and production quality, while procurement specialists can rely on ISO certification for consistent tool performance.
