IEC 60399:2004/AMD1:2008

IEC 60399:2004/AMD1:2008 is an amendment connected to the parent document IEC 60399:2004, focused on the barrel thread for lampholders with shade holder ring. It is relevant when reviewing product definitions, component interfaces, or technical documentation for lampholder assemblies where dimensional and compatibility control matter. For engineering, procurement, and compliance teams, IEC 60399:2004/AMD1:2008 helps identify the modified requirements that may affect product evaluation, technical validation, and conformity assessment workflows.

IEC 60399:2004/AMD1:2008 standard overview

This amendment serves as a supporting technical reference rather than a standalone specification, updating the parent IEC 60399:2004 document for the barrel thread arrangement used with lampholders and shade holder rings. In practice, it is consulted to understand how the referenced design details should be interpreted for manufacture, inspection, or compatibility checks. Teams involved in electrical equipment documentation, component procurement, or engineering review may use it to align drawings, specifications, and acceptance criteria with the revised requirements.

Applications of IEC 60399:2004/AMD1:2008

IEC 60399:2004/AMD1:2008 is typically used in workflows involving lampholder components, lighting product development, and associated hardware verification. It may support technical assessment of threaded interfaces, dimensional coordination, and assembly compatibility where shade holder rings are part of the design. Laboratories, product compliance teams, and manufacturers can use it during testing workflows, documented evaluation, and quality workflows to confirm that a component or assembly follows the intended parent standard with the amendment applied.

Why IEC 60399:2004/AMD1:2008 matters

For organizations working on lighting-related electrical components, this amendment matters because even small interface changes can affect fit, interchangeability, and compliance outcomes. Using IEC 60399:2004/AMD1:2008 during technical review helps reduce mismatch risk, supports consistency in inspection and procurement, and improves preparedness for conformity assessment. It also provides a clearer reference point for engineering documentation, operational consistency, and quality assurance when the parent standard needs to be interpreted with the amendment in place.
