IEC 60061-1:1969/AMD35:2004 is an amendment to the parent reference for lamp caps and holders together with gauges for the control of interchangeability and safety, focusing on Part 1: Lamp caps. It is relevant when engineers, procurement teams, and conformity assessment specialists need to understand how a change affects component compatibility, gauge use, and safety-related dimensional control. As a supporting document to IEC 60061-1:1969, IEC 60061-1:1969/AMD35:2004 helps maintain consistent technical review and documented evaluation across lighting component specifications.

Purpose of IEC 60061-1:1969/AMD35:2004

The purpose of IEC 60061-1:1969/AMD35:2004 is to modify the underlying rules and reference material for lamp caps within the broader lamp cap and holder system. In practice, amendments like this are used to keep technical documentation aligned with updated interchangeability or safety control requirements. For organizations handling engineering documentation, laboratory evaluation, or product validation, it serves as a compliance reference that supports accurate interpretation of the parent document and helps reduce ambiguity during technical assessment.

Compliance applications of IEC 60061-1:1969/AMD35:2004

IEC 60061-1:1969/AMD35:2004 may be used in product evaluation, supplier review, and testing workflows involving lamp caps, holders, and associated gauges. It is especially relevant where fit, interchangeability, and safety-related dimensional checks are part of qualification or conformity assessment preparation. Laboratories and manufacturers may consult it during verification activities to confirm that component definitions and gauge-based control expectations are being applied consistently in engineering specification reviews and quality workflows.

Benefits of IEC 60061-1:1969/AMD35:2004

Using IEC 60061-1:1969/AMD35:2004 alongside the parent document can improve operational consistency by keeping amendment-controlled requirements visible during technical review. That supports safer component selection, more reliable interoperability checks, and clearer procurement decisions for lamp caps and holders. It also helps reduce risk in compliance workflows by providing a documented basis for testing consistency, engineering validation, and conformity assessment, particularly where exact fit and safety-related control points must be confirmed before release or certification.

• Amendment reference tied to the parent lamp cap specification for controlled technical use
• Supports interchangeability and safety-focused review of lamp caps and holder interfaces
• Useful for gauge-based verification, laboratory checks, and documented evaluation
• Helps procurement and compliance teams interpret updated requirements with the parent document
