IEC 60061-3:1969/AMD47:2013 is a supporting amendment to the parent document IEC 60061-3:1969, focused on Amendment 47 - Lamp caps and holders together with gauges for the control of interchangeability and safety - Part 3: Gauges. For engineering, testing, and procurement teams, it provides a controlled reference for interpreting changes linked to lamp cap and holder gauges used in interchangeability and safety-related verification. IEC 60061-3:1969/AMD47:2013 is therefore relevant where documented evaluation, technical review, and compliance workflows depend on the correct version of the underlying gauge requirements.

Overview of IEC 60061-3:1969/AMD47:2013

This amendment belongs to the IEC 60061-3 series and should be read as a modifying document tied to the parent reference rather than a standalone technical specification. Its scope is centered on gauges used for lamp caps and holders, supporting dimensional control and consistency in product assessment. In practical terms, IEC 60061-3:1969/AMD47:2013 helps organizations align technical documentation, verification activities, and conformity assessment work with the updated gauge requirements relevant to interchangeability and safety.

Compliance applications of IEC 60061-3:1969/AMD47:2013

IEC 60061-3:1969/AMD47:2013 is commonly consulted during product evaluation, laboratory evaluation, and conformity assessment for lighting-related components that rely on controlled lamp cap and holder interfaces. It may support procurement review, technical validation, and quality workflows where the correct gauge reference is needed to confirm fit, interchangeability, or acceptance criteria. For manufacturers, test laboratories, and compliance teams, this amendment can be useful when maintaining traceable engineering documentation and ensuring that verification methods remain aligned with the parent document.

Importance of compliance with IEC 60061-3:1969/AMD47:2013

Using the correct amendment reference matters because gauge definitions directly affect consistency, safety, and interoperability in technical assessment. When organizations work from an updated supporting document like IEC 60061-3:1969/AMD47:2013, they reduce the risk of using outdated acceptance criteria during testing workflows or regulatory preparation. That can improve engineering validation, support conformity assessment preparation, and help maintain operational consistency across procurement, inspection, and quality assurance processes tied to lamp cap and holder interfaces.

• Supporting amendment linked to the parent gauge reference for lamp caps and holders
• Relevant to interchangeability and safety-related verification of interface dimensions
• Useful for test laboratories, engineering teams, and compliance documentation control
• Helps align technical review and procurement checks with the correct document set
