Overview

The IEC 60968:1988/AMD2:1999 amendment addresses updated safety requirements for self-ballasted lamps used in general lighting services. Developed by the International Electrotechnical Commission (IEC), this amendment builds upon the existing IEC 60968 standard to reinforce safety protocols, marking, and mechanical and electrical performance criteria for self-ballasted lamps.

This standard is essential for manufacturers, testing laboratories, and regulatory bodies involved in the design, production, and certification of energy-efficient lighting solutions. It helps ensure that self-ballasted lamps meet critical safety standards, protecting users and electrical systems from hazards such as electrical shock, overheating, and mechanical failure.


Key Topics

  • Marking and Labels
    The amendment specifies updated marking requirements to include special conditions or restrictions necessary for lamp operation, such as compatibility with dimming circuits. Lamps that are not suitable for dimming may carry a specific IEC symbol indicating this limitation.

  • Interchangeability and Dimensions
    Detailed requirements for testing lamp cap interchangeability and dimensions are referenced via IEC 60061-3 gauge sheets. This includes caps such as B22d, B15d, E27, E26, and E14, with precise measurements for insertion, retention, and thread dimensions to ensure compatibility with lamp holders.

  • Protection Against Electric Shock
    Modified stipulations clarify compliance testing using gauges in accordance with IEC 60061-3. Special attention is given to various cap types, with some specifications, such as for E26 caps and bayonet insulation resistance, under consideration.

  • Mechanical Strength and Torsion Resistance
    Mechanical robustness is emphasized with defined torque resistance levels for lamp caps:

    • B22d and E26/E27 caps: 3 Nm
    • B15d and E14 caps: 1.15 Nm
      The standard mandates that caps must remain firmly attached during torque application, allowing minimal relative movement in uncemented caps. Post-test compliance with accessibility and safety is required.
  • Electrical Insulation and Strength
    Electrical strength parameters focus on insulation resistance and the spacing between conductive and foil parts. Certain criteria, including insulation resistance for bayonet caps, are still under evaluation to ensure continued safety improvements.

  • Temperature Rise Limits
    The amendment defines maximum temperature rise (Δt) limits for lamp caps during operation, measured per IEC 60360. Limits vary by cap type, for instance, 125 K for B22d and 120 K for B15d, E27, and E14 caps. These limits are critical to prevent overheating, extend lamp life, and ensure user safety.

  • Test Equipment and Procedures
    Figures and tables provide detailed specifications for test holders and gauges necessary for mechanical and electrical testing, including dimensions with tolerances for accuracy in compliance verification.


Applications

  • Manufacturing Compliance
    Lamp manufacturers must adhere to these safety amendments to certify their self-ballasted lamps for global markets. Compliance ensures lamps are safe for consumer use and compatible with existing fixtures.

  • Product Testing and Certification
    Testing laboratories utilize the detailed mechanical torque, marking, temperature rise, and electrical insulation criteria to evaluate lamp safety systematically and objectively.

  • Lighting Design and Installation
    Electrical engineers and installers benefit from understanding restrictions on dimming compatibility and torque requirements to optimize lighting system safety and performance.

  • Regulatory Adoption
    National and international regulatory bodies may reference this amendment when updating safety codes and certification mandates for energy-efficient lighting products.


Related Standards

  • IEC 60968
    The base standard for self-ballasted lamps, detailing fundamental safety and performance requirements.

  • IEC 60061-3
    Defines gauges and dimensions of lamp caps, essential for interchangeability compliance checks.

  • IEC 60360
    Specifies measurement procedures for temperature rise of lamps and caps during operation.

  • IEC 928/99
    Provides symbols and indicators related to special operating restrictions such as dimmer incompatibility.


Conclusion

IEC 60968:1988/AMD2:1999 amendment enhances safety benchmarks for self-ballasted lamps by updating marking protocols, dimensional compatibility, mechanical strength, electrical insulation, and temperature rise requirements. Compliance with this amendment ensures high reliability and safety in general lighting applications, supporting sustainable and secure lighting system deployment worldwide. Manufacturers, testers, and regulators are encouraged to integrate these updated safety requirements for continued product excellence and regulatory adherence.
