IEC 60061-2:1969/AMD51:2016 is an amendment to the base document for lamp caps and holders together with gauges for the control of interchangeability and safety, focused here on lampholders. It is relevant where engineering teams, procurement functions, and conformity assessment groups need a precise technical document to support product evaluation, documented evaluation, and compliance workflows. As a modifying reference to IEC 60061-2:1969, it helps keep technical review aligned with the current requirements applied to lamp-related components used in electrical equipment.

Overview of IEC 60061-2:1969/AMD51:2016

This amendment updates the lampholder part of the IEC 60061 series, which addresses lamp caps and holders together with gauges used to control interchangeability and safety. In practice, IEC 60061-2:1969/AMD51:2016 is used as a supporting technical reference when reviewing design compatibility, dimensional conformity, and gauge-based acceptance criteria for lampholders. For organizations performing technical assessment or engineering documentation control, it provides an authoritative change set connected to the parent document rather than a standalone specification.

Compliance applications of IEC 60061-2:1969/AMD51:2016

This amendment is most relevant in product development, laboratory evaluation, and quality workflows involving lampholders and related lamp interface components. It may be consulted during verification activities, supplier review, or conformity assessment preparation to confirm that the applicable requirements from the parent document are being applied correctly. Manufacturers, test laboratories, and certification teams can use IEC 60061-2:1969/AMD51:2016 as part of a controlled technical file when checking interchangeability, safety-related fit, and operational consistency across production or procurement decisions.

Importance of compliance with IEC 60061-2:1969/AMD51:2016

Compliance with IEC 60061-2:1969/AMD51:2016 matters because even a focused amendment can affect compatibility, testing consistency, and risk reduction in lamp-holder applications. Using the updated reference helps organizations maintain aligned engineering validation and avoid gaps in technical compliance when comparing components against the applicable gauges and requirements. It also supports procurement review and conformity assessment by providing a clear basis for acceptance decisions, which can reduce interface errors and improve safety-oriented documentation across the product lifecycle.

• Supporting amendment for the lampholder section of IEC 60061-2:1969
• Useful for interchangeability checks and gauge-based technical validation
• Relevant to product evaluation, test planning, and compliance documentation
• Helps maintain consistency in engineering review and procurement acceptance
