IEC 60061-4:1990/AMD14:2011 is a supporting amendment to the Lamp caps and holders together with gauges for the control of interchangeability and safety series, focused on Part 4: Guidelines and general information. It is relevant where engineering teams, laboratories, and procurement specialists need a reliable compliance reference for understanding how lamp cap and holder requirements are organized and applied. For technical review and documented evaluation, IEC 60061-4:1990/AMD14:2011 helps clarify the parent document framework and supports safer, more consistent product assessment.

What is IEC 60061-4:1990/AMD14:2011?

This document is Amendment 14 to IEC 60061-4:1990, so it should be used as a modifying reference connected to the parent publication rather than as a standalone engineering specification. Based on the title, it provides guidelines and general information for lamp caps and holders together with gauges used to control interchangeability and safety. That makes it useful in compliance workflows where teams need to interpret the structure of the reference system, support technical validation, and maintain alignment with documented requirements.

Applications of IEC 60061-4:1990/AMD14:2011

IEC 60061-4:1990/AMD14:2011 is typically consulted in product evaluation, conformity assessment, and quality workflows involving lamp cap and holder interfaces. It may be used by manufacturers, testing laboratories, certification teams, and procurement groups when reviewing compatibility, gauging practices, or technical documentation linked to lighting components. In practice, it supports engineering documentation, verification activities, and regulatory preparation where consistency between parts, holders, and associated gauges is important for operational consistency and safety-related review.

Why is IEC 60061-4:1990/AMD14:2011 important?

For organizations working with lighting hardware, this amendment helps preserve a controlled technical reference point for interchangeability and safety-related assessment. It can reduce interpretation risk during testing workflows, support conformity assessment preparation, and improve documented evaluation of lamp cap and holder compatibility. Because it is tied to the parent part 4 document, it also helps teams track updates without losing the context needed for engineering validation, procurement review, and quality assurance. That makes it a practical compliance reference in controlled technical libraries.
