What is IEC 60061-4 ?

IEC 60061-4: A Technical Standard for Lamp Cap Gauges


The lighting industry plays a vital role in our daily lives. providing us with an estimated 90% of the energy we consume. As lighting technology continues to advance. it is essential to ensure the compatibility and safety of various components such as lamps. lamp holders. and lamp caps. IEC 60061-4. also known as "Lamp caps and holders together with gauges for the control of interchangeability and safety - Part 4: Guidelines and general information. " is a technical specification developed by the International Electrotechnical Commission (IEC) that provides comprehensive guidelines for lamp caps and holders used in various lighting applications.

Ensuring Compatibility and Safety

Without IEC 60061-4. there would be no universal standard for lamp caps. which could lead to compatibility issues and potential safety hazards. The main objective of IEC 60061-4 is to ensure the interchangeability. proper functioning. and safety of lamp caps and holders. It provides manufacturers. engineers. and designers with detailed specifications and requirements to develop reliable lamp cap and holder designs.

The Scope of IEC 60061-4

IEC 60061-4 covers a wide range of topics related to lamp caps and holders. including their design. construction. and testing. The standard provides guidelines for the operation of cap gauges. which are essential tools for manufacturers to test and ensure the proper fit of lamp caps on lamp holders.

Some of the key provisions of IEC 60061-4 include:

* The standard provides comprehensive guidelines for the design. construction. and testing of lamp caps and holders.

* The standard covers various aspects of lamp caps and holders. including their dimensions. . and performance characteristics.

* The standard specifies the testing procedures for lamp caps and holders. including the tests that manufacturers must perform to ensure their compatibility and safety.

* The standard provides guidance for manufacturers on how to use cap gauges to monitor the proper fit of lamp caps on lamp holders.


IEC 60061-4 is an essential technical standard that plays a crucial role in ensuring the compatibility and safety of lamps and lamp holders in the lighting industry. It provides comprehensive guidelines for manufacturers. engineers. and designers to develop reliable lamp cap and holder designs. By following the guidelines provided by IEC 60061-4. manufacturers can ensure that their products meet the necessary safety and compatibility standards. ultimately providing consumers with safe and reliable lighting solutions.
