IEC 60061-3:1969/AMD49:2014 provides Amendment 49 to the parent document IEC 60061-3:1969, focusing on lamp caps and holders together with gauges for controlling interchangeability and safety. For engineering, procurement, and compliance teams, it is a supporting technical reference that helps update documented requirements for gauge-based verification of lamp-related components. In workflows that depend on fit, consistency, and safe integration, IEC 60061-3:1969/AMD49:2014 is relevant for technical review and conformity assessment against the amended gauge provisions.

Purpose of IEC 60061-3:1969/AMD49:2014

The purpose of IEC 60061-3:1969/AMD49:2014 is to modify the gauge-related requirements associated with lamp caps and holders so that interchangeability and safety control remain aligned with the parent document. As an amendment, it should be read as part of the existing technical framework rather than as a standalone specification. It is useful where teams need a current compliance reference for documented evaluation, design verification, or laboratory assessment of lamp cap and holder interfaces.

Compliance applications of IEC 60061-3:1969/AMD49:2014

Organizations may use IEC 60061-3:1969/AMD49:2014 when reviewing product files, inspection criteria, or test documentation for lamp caps, holders, and related gauges. It can support technical validation during product evaluation, supplier qualification, and conformity assessment preparation, especially where dimensional control affects interchangeability. The amendment is also relevant in quality workflows that depend on consistent gauge use, traceable acceptance criteria, and risk management for electrical equipment entering regulated markets.

Benefits of IEC 60061-3:1969/AMD49:2014

Using IEC 60061-3:1969/AMD49:2014 helps keep engineering documentation aligned with the amended gauge requirements tied to lamp caps and holders. That can improve testing consistency, reduce interpretation errors during verification activities, and support safer product integration. For procurement and compliance teams, it offers a clearer basis for technical review, supplier communication, and regulatory preparation. In practice, it supports operational consistency where interchangeability, safety, and documented conformity matter.
