IEC 60061-4:1990/AMD11:2007 provides an amendment to the guidelines and general information for lamp caps and holders, together with gauges used to control interchangeability and safety. For engineering, testing, and procurement teams, the reference is relevant where product compatibility, dimensional control, and safe fitment need to be checked against an established technical document. IEC 60061-4:1990/AMD11:2007 is best understood as a supporting update to the parent document, helping maintain alignment in technical review and conformity assessment workflows.

Overview of IEC 60061-4:1990/AMD11:2007

This amendment supports the framework set out in IEC 60061-4:1990 by refining the guidelines and general information used for lamp caps and holders and the associated gauges. Its practical purpose is to help organizations interpret and apply the parent document consistently when managing interchangeability and safety considerations. In documented evaluation and technical validation work, it may be used alongside the base publication to support engineering documentation, product evaluation, and quality workflows tied to lighting component compliance.

Compliance applications of IEC 60061-4:1990/AMD11:2007

IEC 60061-4:1990/AMD11:2007 is commonly relevant in laboratory evaluation, supplier review, and regulatory preparation for lighting components that depend on precise cap-and-holder compatibility. It can support testing workflows where gauges, fit verification, and dimensional checks are part of conformity assessment preparation. Procurement teams and compliance engineers may also use it as a technical reference when comparing product descriptions, validating component interchangeability, or checking whether an item aligns with the parent specification and its subsequent amendment history.

Importance of compliance with IEC 60061-4:1990/AMD11:2007

Using the amendment in the correct context helps reduce risk in safety-critical and interoperability-focused applications. For lamp caps and holders, even small deviations can affect fit, operational consistency, and the reliability of technical assessment results. Aligning internal procedures with the parent document and its amendment can improve testing consistency, support conformity assessment, and strengthen procurement decisions. It also helps teams maintain traceable engineering documentation when validating products against the expected interchangeability and safety framework.
