ISO 5745:2004

Overview

ISO 5745:2004 - "Pliers and nippers - Pliers for gripping and manipulating - Dimensions and test values" defines the principal dimensions and required test values for pliers used for gripping and manipulating. It sets nominal lengths, head/neck dimensions and performance criteria so that pliers reliably meet functional requirements and can be verified by tests described in ISO 5744:2004. General technical requirements and marking are covered by ISO 5743:2004.

Keywords: ISO 5745:2004, pliers dimensions, test values, pliers for gripping and manipulating, standards for hand tools

Key topics and technical requirements

• Scope and purpose: Specifies principal dimensions and test criteria to verify aptitude to function in conformity with ISO 5744. Illustrative shapes are examples and do not restrict manufacturer design.
• Pliers types covered:
  • Round nose pliers (short and long noses)
  • Flat nose pliers (short and long noses)
  • Snipe nose pliers (with and without side cutter)
  • Flat nose pliers with side cutter
• Dimensional data: Nominal lengths and head dimensions are provided (examples in the standard run across typical tool lengths and head widths).
• Test values and methods:
  • Torsion tests (torque and twist angles)
  • Load tests (applied load, maximum load, and permissible permanent set s)
  • Cutting tests for pliers with side cutters (cutting force and test-wire diameter; data for medium-hard wire are referenced to ISO 5744)
  • Where lever ratios or reach differ, ISO 5744 formulas are used to verify compliance.
• Designation and marking: Standardized designation examples (e.g., "Round nose pliers 203 - ISO 5745 - 140 - S") and marking requirements reference ISO 5743.

Applications and who uses this standard

• Tool manufacturers - design and dimension pliers to meet internationally recognized sizes and performance metrics.
• Quality control and test laboratories - perform torsion, load and cutting tests per ISO 5744 using ISO 5745 dimensional references.
• Procurement and specification writers - specify compliant pliers in purchase orders to ensure interchangeability and safety.
• Compliance and certification bodies - verify that products meet required test values and marking rules.
