IEC 60352-6:2022

Overview

IEC 60352-6:2022 is an international standard developed by the International Electrotechnical Commission (IEC) focusing on solderless insulation piercing connections. This standard applies specifically to connections made with stranded wires, tinsel wires, insulated flat conductors, and flat flexible circuitries commonly used in electrical and electronic equipment. It establishes general requirements, test methods, and practical guidelines to ensure deployment of electrically stable connections under defined mechanical, electrical, and environmental conditions.

The primary objective of IEC 60352-6:2022 is to assess the suitability of insulation piercing connections through standardized qualification and application tests. This facilitates comparison of test results regardless of variations in connection tools or designs, supporting uniform safety and reliability.

Key Topics

• Scope and Definitions
  Establishes terms and criteria applicable to insulated conductors and piercing connections, including materials, dimensions, surface finishes, and design features.

• Workmanship and Tools
  Specifies quality of workmanship and defines necessary tool characteristics to make reliable insulation piercing terminations without solder.

• Test Methods and Procedures
  Comprehensive mechanical, electrical, and climatic testing protocols, such as:

  • Tensile strength and bending tests for wires and conductors
  • Vibration resistance to simulate operational stresses
  • Measurement of contact resistance to verify conductivity
  • Electrical load and temperature endurance
  • Rapid temperature changes and damp heat cyclic tests
  • Corrosion resistance via flowing mixed gas exposure

• Qualification and Application Test Schedules
  Standardized schedules and flowcharts guide consistent testing of components and connections to verify performance across different environmental and mechanical conditions.

• Practical Guidance
  Annexes provide detailed advice on selecting materials, tool usage, conductor specifications, current-carrying capacities, and axial load considerations critical for real-world applications.
