IEC 60061-3:1969/AMD31:2003 is an amendment to Lamp caps and holders together with gauges for the control of interchangeability and safety - Part 3 : Gauges, and it is relevant where controlled gauging supports interchangeability and safety checks for lamp cap and holder systems. For engineering, testing, and procurement teams, the document helps anchor technical review against the parent reference while keeping conformity assessment aligned with the amended requirements. It is a practical compliance reference for organizations working with verified component compatibility and documented evaluation.

What is IEC 60061-3:1969/AMD31:2003?

This reference functions as a modifying document connected to IEC 60061-3:1969, rather than a standalone primary specification. Based on the title, its technical purpose is to update the gauge-related content used to control interchangeability and safety for lamp caps and holders. In practice, it may be consulted during technical validation, laboratory evaluation, and engineering documentation reviews when teams need to confirm that component gauging rules remain consistent with the amended text.

Applications of IEC 60061-3:1969/AMD31:2003

Organizations involved in lighting-component design, product evaluation, and conformity assessment may use this amendment alongside the parent document when checking gauge requirements for lamp caps and holders. It is most relevant in testing workflows, quality workflows, and procurement review processes where dimensional control and interchangeability affect operational consistency. The reference can also support internal technical assessment, supplier documentation checks, and regulatory preparation when evidence is needed to show alignment with the updated gauging provisions.

Why is IEC 60061-3:1969/AMD31:2003 important?

Accurate gauge control is important because it supports safety, interoperability, and repeatable verification activities for lamp cap and holder interfaces. By applying the amendment together with the parent document, teams can reduce risk in product evaluation and improve the consistency of technical compliance decisions. It also helps laboratories and compliance teams maintain stable test criteria, which is valuable for conformity assessment preparation, procurement decisions, and engineering validation where interchangeability must be demonstrated with documented evidence.
