IEC 60061-1:1969/AMD34:2004 is an amendment to the parent document IEC 60061-1:1969, addressing Amendment 34 - Lamp caps and holders together with gauges for the control of interchangeability and safety - Part 1: Lamp caps. It is relevant where organizations need a technical reference for lamp cap identification, interchangeability control, and safety-related dimensional checking. In procurement, engineering review, and compliance workflows, IEC 60061-1:1969/AMD34:2004 helps keep product documentation aligned with the applicable lamp-cap definitions and gauge-related requirements used for verification activities.

IEC 60061-1:1969/AMD34:2004 standard overview

This supporting document modifies the parent lamp-cap reference by updating requirements connected to lamp caps within the IEC 60061 series. Its technical purpose is generally to maintain consistency in the interchangeability and safety framework used for lamp caps and associated gauges. For engineering teams and laboratories, it serves as a focused compliance reference during technical assessment, documented evaluation, and product validation. Because it is an amendment, it should be used together with IEC 60061-1:1969 when reviewing applicable dimensions, interfaces, or conformity assessment records.

Applications of IEC 60061-1:1969/AMD34:2004

IEC 60061-1:1969/AMD34:2004 is typically used in lighting product development, component qualification, and laboratory evaluation where lamp caps must be checked against recognized interchangeability and safety criteria. It may also support supplier documentation review, tooling decisions, and inspection plans for electrical equipment that incorporates lamp-cap interfaces. In quality workflows, it can assist with technical validation, incoming inspection, and conformity assessment preparation by giving teams a clear amendment reference tied to the parent technical document.

Why IEC 60061-1:1969/AMD34:2004 matters

For organizations working with lamp-cap components, this amendment matters because small interface changes can affect safety, fit, and operational consistency. Using the correct supporting reference helps reduce risk during design approval, testing workflows, and procurement checks. It also supports more reliable technical compliance by keeping specifications, gauges, and verification activities aligned with the parent document. In regulated or audited environments, that consistency can improve engineering documentation quality and reduce rework during conformity assessment.
