IEC 60061-4:1990/AMD16:2018 is a supporting amendment to the document titled Amendment 16 - Lamp caps and holders together with gauges for the control of interchangeability and safety - Part 4: Guidelines and general information. It is relevant when organizations need to review changes connected to lamp cap and holder interchangeability, gauge use, and safety-related guidance. For engineering teams, test laboratories, and procurement staff, IEC 60061-4:1990/AMD16:2018 helps keep technical document sets aligned with the parent reference and supports consistent compliance workflows.

IEC 60061-4:1990/AMD16:2018 standard overview

This amendment updates the parent document IEC 60061-4:1990 and should be read as part of that technical framework rather than as a standalone specification. Its role is to support the guidelines and general information used in the broader lamp caps and holders series, with attention to interchangeability and safety control through gauges. In practice, it is useful for technical review, documented evaluation, and conformity assessment preparation where accurate reference control matters across design, testing, and approval activities.

Applications of IEC 60061-4:1990/AMD16:2018

Organizations may use IEC 60061-4:1990/AMD16:2018 when maintaining engineering documentation for lighting-related components, reviewing gauge-based verification activities, or checking the consistency of product data against the parent reference. It can support laboratory evaluation, quality workflows, and procurement screening where interchangeability requirements are part of the decision process. The document is also relevant in compliance preparation for manufacturers, test houses, and component suppliers that need a reliable amendment trail for lamp cap and holder references.

Why IEC 60061-4:1990/AMD16:2018 matters

Keeping amendment documents like IEC 60061-4:1990/AMD16:2018 within the controlled standards set helps reduce risk during technical validation and conformity assessment. Because lamp caps, holders, and gauges are tied to safety and interchangeability, even supporting changes can affect testing consistency and operational consistency. Using the correct amendment alongside the parent document helps teams avoid version mismatch, strengthens regulatory preparation, and improves confidence in procurement, inspection, and compliance workflows.

• Supports controlled reference checking for lamp cap and holder guidance tied to the parent document.
• Useful for gauge-based verification activities in test laboratories and product evaluation workflows.
• Helps maintain documentation accuracy for safety and interchangeability-related compliance review.
• Relevant for procurement and engineering teams managing technical document sets and amendment history.
