IEC 60061-4:1990/AMD15:2017 provides Amendment 15 to the guidance and general information associated with lamp caps and holders, together with the gauges used to control interchangeability and safety. For engineering teams and procurement groups, IEC 60061-4:1990/AMD15:2017 is relevant when maintaining technical consistency across lighting component selection, verification activities, and conformity assessment records. Because it is an amendment to the parent document, it should be read as a supporting technical reference that updates the existing framework rather than replacing it.

Overview of IEC 60061-4:1990/AMD15:2017

The scope indicated by the title points to general guidance for the lamp-cap and lamp-holder system, with emphasis on gauges that help confirm interchangeability and safety-related fit. IEC 60061-4:1990/AMD15:2017 is therefore useful in documented evaluation, technical review, and specification control where consistent mechanical compatibility matters. In practice, it supports teams that need to align product selection, inspection criteria, and design documentation with the parent IEC 60061-4:1990 framework and its later amendment history.

Compliance applications of IEC 60061-4:1990/AMD15:2017

This amendment may be used in compliance workflows for lighting equipment, component procurement, laboratory evaluation, and product qualification activities involving lamp caps and holders. It is especially relevant when gauges are used to check interchangeability during verification or acceptance testing. Organizations working on technical documentation, supplier review, or conformity assessment preparation can use IEC 60061-4:1990/AMD15:2017 to support consistent interpretation of the parent guidance and to reduce ambiguity during engineering validation and quality workflows.

Importance of compliance with IEC 60061-4:1990/AMD15:2017

Using the amendment alongside the parent document helps improve safety, interoperability, and testing consistency in lighting-related engineering and procurement processes. IEC 60061-4:1990/AMD15:2017 can support risk reduction by clarifying how interchangeability is assessed and how gauge-based checks are referenced in technical documentation. For manufacturers, laboratories, and compliance teams, that can streamline conformity assessment preparation, strengthen quality assurance, and reduce the likelihood of component mismatch during product evaluation.

• Supporting reference for lamp cap and holder guidance within the IEC 60061 framework
• Useful for gauge-based checks tied to interchangeability and safety-related fit
• Relevant to technical review, supplier documentation, and verification activities
• Helps maintain consistency in compliance workflows and product evaluation records
