IEC 60061-1:1969/AMD45:2011 is a supporting amendment to the parent reference IEC 60061-1:1969, updating the technical framework for lamp caps and holders together with gauges for the control of interchangeability and safety. For organizations involved in lighting component design, verification, procurement, or conformity assessment, it helps clarify the dimensional and compatibility controls that underpin safe and consistent product selection. As an amendment, it should be read together with the base document when conducting technical review or compliance workflows.

Overview of IEC 60061-1:1969/AMD45:2011

This amendment refines the specification set for lamp caps within the broader lamp cap and holder system, which is used to manage interchangeability and safety through defined gauge-based control. IEC 60061-1:1969/AMD45:2011 is therefore relevant where engineering documentation, product evaluation, or laboratory evaluation depends on the correct interpretation of the parent document and its updates. It supports technical validation by helping users align component identification and interface expectations with the current amended reference.

Compliance applications of IEC 60061-1:1969/AMD45:2011

Typical compliance uses include design checks for lamp-cap compatibility, purchasing review for replacement or embedded lighting parts, and verification activities in test laboratories or quality workflows. The amendment may also be relevant in regulatory preparation where documented evaluation of lamp caps and holders is needed to support conformity assessment. Teams working on lighting equipment or related electrical equipment can use it as part of technical assessment to confirm that the applicable parent reference is being applied with the correct amendment history.

Importance of compliance with IEC 60061-1:1969/AMD45:2011

Using IEC 60061-1:1969/AMD45:2011 correctly helps reduce risk in product selection and approval by improving interchangeability control and supporting safety-focused engineering validation. For manufacturers, test houses, and procurement teams, the amendment can improve testing consistency and operational consistency when documenting how a lamp cap or holder interface is evaluated. It also supports conformity assessment preparation by making it easier to trace the applicable technical document and maintain clear compliance reference records.

• Amendment tied to the parent lamp-cap reference, not a standalone technical specification
• Relevant to interchangeability and safety control for lamp caps and holders
• Useful in engineering documentation, verification activities, and laboratory evaluation
• Supports procurement review and conformity assessment preparation for lighting components
