Overview

IEC 60352-2:1990/AMD2:2002 is an important international standard published by the International Electrotechnical Commission (IEC) that addresses solderless crimped connections-a fundamental method for creating electrical connections without soldering. This amendment (Amendment 2) updates the general requirements, test methods, and practical guidance related to solderless crimped connections for electromechanical components and electronic equipment.

Prepared by IEC sub-committee 48B (Connectors), the document ensures uniformity and reliability in manufacturing and testing crimped connections worldwide. It harmonizes test procedures and sets mechanical and dimensional criteria to optimize performance, durability, and environmental considerations.

Key Topics

  • General Requirements for Crimped Connections
    Detailed specifications define acceptable conductor cross-sections, dimensional tolerances of crimp barrels, and materials used. The specifications ensure consistent and reliable electrical and mechanical connections without solder.

  • Test Methods
    The standard outlines strict mechanical tests, such as tensile strength, conducted following IEC 60512 Test 16d procedures. Minimum tensile strength values based on conductor sizes (ranging from 0.05 mm² to 10 mm²) are provided to verify crimp integrity. This testing guarantees connectors withstand mechanical stress during installation and operation.

  • Dimensional Guidelines
    Updated tables specify barrel dimensions (length, diameter) for different conductor ranges to ensure proper fit and effective crimping. These dimensional standards help manufacturers produce compatible parts that deliver optimal contact pressure and electrical performance.

  • Practical Guidance
    The amendment includes notes on specialized cases like connections involving multiple wires, emphasizing the practical application of test methods and mechanical requirements.

  • Environmental Considerations
    In alignment with IEC Guide 109, the standard highlights the need to minimize environmental impact throughout the product lifecycle. It acknowledges that some materials currently permitted may have environmental drawbacks but encourages future elimination as better alternatives emerge.

Applications

IEC 60352-2 Amendment 2 is vital for manufacturers, designers, and quality assurance engineers involved with:

  • Connector Assembly in Electronics
    Used extensively in producing connectors for electronic devices, ensuring reliable solderless connections critical for optimal signal and power transmission.

  • Electrical Wiring and Harnesses
    Provides assurance for wiring harnesses in automotive, aerospace, and industrial applications where crimped connections are preferred for ease of assembly and serviceability.

  • Industrial Equipment Manufacturing
    Applies to electromechanical components needing robust electrical contacts without soldering, including control panels, instrumentation, and consumer electronics.

  • Quality Control and Certification
    Serves as a benchmark for testing laboratories and certification bodies verifying crimped connections meet international strength and dimensional standards.

Related Standards

This amendment references and complements several IEC and ISO standards to provide a comprehensive framework:

  • IEC 60512 – Tests and measurements for connectors, including tensile strength testing procedures.

  • IEC 60050(581) – Electrotechnical vocabulary, providing precise terminology used in connection components.

  • IEC 60130-7 – Circular multipole connectors for low-frequency applications.

  • IEC 60189-3 – Specifications for low-frequency cables and wires with PVC insulation.

  • IEC 60673, IEC 60760, IEC 61210 – Standards covering related connector types, quick-connect terminals, and safety requirements.

  • IEC Guide 109 – Environmental aspects in electrotechnical standards, guiding materials selection and design.

  • ISO 6507-1 – Metallic materials hardness testing, relevant for quality control of connector components.

Conclusion

IEC 60352-2:1990/AMD2:2002 provides authoritative, updated guidance and requirements for solderless crimped connections in electromechanical and electronic equipment. It ensures uniform test methods and performance levels critical for high-quality, reliable, and environmentally conscious crimped connection solutions. Engineers, manufacturers, and quality professionals benefit from applying these standards to improve durability, safety, and compliance in electrical interconnections globally.
