What is IEC 60238?

IEC 60238, also known as the International Electrotechnical Commission standard 60238, is a widely recognized technical specification for lampholders. It specifies the requirements for Edison screw lampholders of various types, used for general lighting purposes.

The Purpose and Significance of IEC 60238

The main purpose of IEC 60238 is to ensure compatibility and safety in the use of lampholders worldwide. By defining the dimensions, specifications, and testing procedures, this standard provides guidelines for manufacturers, ensuring that their products meet certain quality and safety criteria.

IEC 60238 is particularly significant because it promotes international harmonization, allowing users to easily find compatible lampholders regardless of their geographical location. This reduces unnecessary variations and complications in the usage of lamps and facilitates market access for manufacturers.

Main Requirements and Specifications of IEC 60238

IEC 60238 specifies several key requirements and specifications for lampholders. These include:

Threaded Connection: The standard defines the thread type, pitch, and dimensions of the screw base, ensuring uniformity and interchangeability.

Contact Making: IEC 60238 outlines the necessary conditions for efficient electrical contact between the lampholder and the bulb, ensuring proper functioning and safety.

Mechanical Strength: The standard specifies the mechanical strength requirements for lampholders, ensuring that they can withstand the forces applied during installation and usage without any deformations or failures.

Temperature Resistance: IEC 60238 sets limits on the maximum temperature rise of lampholders during operation, ensuring they can safely handle the heat generated by the lamps.

Conclusion

IEC 60238 plays a crucial role in ensuring standardization, safety, and compatibility in the world of lampholders. By defining the requirements and specifications, it enables manufacturers to produce quality products that meet the needs of users worldwide. This standard not only helps streamline the market but also enhances safety for consumers, instilling confidence in the use of lighting products.
