IEC 60061-1:1969/AMD49:2013

IEC 60061-1:1969/AMD49:2013 is an amendment to the parent document for lamp caps and holders together with gauges for the control of interchangeability and safety, focusing on Part 1: Lamp caps. For engineers, buyers, and compliance teams, it is relevant where lamp-cap dimensions, fit, and safety-related interchangeability need to be checked against a defined technical reference. As a supporting update to IEC 60061-1:1969, it helps maintain alignment in technical review, documented evaluation, and procurement decisions.

Overview of IEC 60061-1:1969/AMD49:2013

This amendment modifies the lamp-cap portion of the IEC 60061 series, which is used to control interchangeability and safety through standardized caps and associated gauges. IEC 60061-1:1969/AMD49:2013 is therefore best understood as a compliance reference connected to the base publication rather than a standalone specification. In practice, it may be consulted during technical validation, product evaluation, and engineering documentation review when assessing whether lamp-cap designs remain consistent with the established dimensional and safety framework.

Compliance applications of IEC 60061-1:1969/AMD49:2013

Organizations may use this amendment in workflows involving lamp hardware design, incoming inspection, conformity assessment, and supplier qualification. It is particularly relevant where lamp caps must interface reliably with holders and gauges used for interchangeability checks. In testing laboratories and quality workflows, IEC 60061-1:1969/AMD49:2013 can support verification activities, technical assessment, and regulatory preparation by clarifying the modified requirements linked to the parent document. It is also useful in procurement review when documenting which referenced revision applies to a specific product.

Importance of compliance with IEC 60061-1:1969/AMD49:2013

Compliance with this amendment supports safe and consistent mating between lamp caps and holders, reducing the risk of fit issues, misapplication, and avoidable nonconformities. For manufacturers and test teams, it strengthens testing consistency and helps align engineering validation with the documented reference set. For procurement and certification workflows, IEC 60061-1:1969/AMD49:2013 can be important when confirming that the correct revision is used during conformity assessment, quality assurance, and product release decisions. It also helps reduce ambiguity when multiple document versions are in circulation.
