IEC 60061-4B:1994 provides a technical reference for Second supplement - Lamp caps and holders together with gauges for the control of interchangeability and safety. Part 4: Guidelines and general information_, making it relevant for organizations that need a structured basis for lamp-cap and holder evaluation. It supports engineering documentation, procurement review, and conformity assessment where interchangeability and safety considerations are part of the product lifecycle. For teams working with lighting components or related verification activities, IEC 60061-4B:1994 can help anchor technical review and compliance workflows.

What is IEC 60061-4B:1994?

IEC 60061-4B:1994 is an original technical document within the IEC 60061 series, focused on guidelines and general information for lamp caps and holders, together with gauges used to control interchangeability and safety. Its purpose is generally to support consistent interpretation of component interfaces and checking methods in engineering and laboratory evaluation. In practice, it is useful when organizations need a compliance reference for technical validation, product evaluation, or documentation tied to fitting compatibility and safety-related control measures.

Applications of IEC 60061-4B:1994

This document is typically relevant in lighting product development, component qualification, and test planning where lamp caps, holders, and associated gauges must be assessed against defined interface expectations. It may be used in quality workflows for engineering documentation, supplier comparison, and laboratory evaluation of compatibility. Procurement teams and compliance professionals often rely on such references when reviewing technical specifications, preparing conformity assessment files, or checking whether electrical equipment designs align with established interchangeability and safety practices.

Why is IEC 60061-4B:1994 important?

IEC 60061-4B:1994 matters because it helps reduce risk where component fit, safety, and repeatable verification are important. Using a common technical reference can improve testing consistency, support operational consistency across suppliers, and strengthen documented evaluation during product validation. For organizations preparing for regulatory preparation or internal approval, it provides a clearer basis for technical assessment and conformity assessment work. That can be especially valuable when decisions affect product compatibility, safety-related inspection, or procurement acceptance.
