IEC 60061-3:1969/AMD43:2011 is an amendment to the technical reference for lamp caps and holders together with gauges used to control interchangeability and safety. It is relevant for organizations that need to verify whether lighting components align with the established gauge-based requirements in IEC 60061-3:1969/AMD43:2011. As a supporting document to the parent reference, it helps engineering, testing, and procurement teams keep documentation aligned with the current conformity assessment and product evaluation framework.

Overview of IEC 60061-3:1969/AMD43:2011

This amendment updates the gauge-related part of the lamp cap and holder system described in the parent document, IEC 60061-3:1969. In practical terms, it supports the technical control of interchangeability and safety for lighting components by refining the gauges used during design review, verification activities, and laboratory evaluation. For teams maintaining engineering documentation or managing a compliance reference library, IEC 60061-3:1969/AMD43:2011 can be an important document for documenting the correct basis of technical validation.

Compliance applications of IEC 60061-3:1969/AMD43:2011

Organizations involved in lamp, holder, and related component assessment may use this amendment during technical review, procurement checks, and test planning where dimensional compatibility is part of the workflow. It is especially relevant when gauge control is needed to support operational consistency, quality workflows, and conformity assessment preparation. In a documented evaluation process, IEC 60061-3:1969/AMD43:2011 can help teams confirm that the correct supporting reference is being applied when reviewing product design, incoming components, or verification procedures.

Importance of compliance with IEC 60061-3:1969/AMD43:2011

Using the correct amendment matters because gauge definitions directly affect interchangeability, fit, and safety-related verification for lamp caps and holders. Keeping documentation current can reduce risk during engineering validation, testing workflows, and procurement review by ensuring that assessments are based on the intended technical requirements. For compliance teams, the document supports traceable conformity assessment preparation and helps avoid errors when comparing components against the parent reference and related amendments.

• Supporting amendment for the gauge-based control of lamp cap and holder interchangeability
• Useful in design verification, dimensional checking, and laboratory evaluation workflows
• Relevant for conformity assessment, procurement review, and technical documentation control
• Helps maintain safety-oriented consistency across lighting component evaluation
