IEC 60061-2C:1972 defines the third supplement to the lamp caps and holders reference system, with a specific focus on lampholders and the gauges used to control interchangeability and safety. For engineers, buyers, and compliance teams, IEC 60061-2C:1972 is relevant when technical documentation must support consistent fit, verification activities, and documented evaluation of lamp-holder interfaces. It helps anchor procurement review and quality workflows around a recognized technical reference for lighting components.

IEC 60061-2C:1972 standard overview

IEC 60061-2C:1972 is a primary technical reference for lampholders within the broader lamp caps and holders series. Its title indicates a supplement that concentrates on the dimensional and functional control needed to support interchangeability and safety through gauges. In practical engineering and conformity assessment work, it may be used to guide technical assessment of component compatibility, support laboratory evaluation, and provide a structured basis for comparing products against defined interface requirements.

Applications of IEC 60061-2C:1972

This document is typically relevant in lighting product development, component sourcing, and test environments where lampholders must be matched with compatible lamp caps. It can support technical validation in design review, incoming inspection, product evaluation, and compliance workflows for electrical equipment that uses standardized lamp interfaces. Manufacturers, test laboratories, and procurement teams may consult it when checking interchangeability criteria, preparing technical documentation, or aligning internal verification activities with established reference dimensions.

Why IEC 60061-2C:1972 matters

Reliable lampholder interchangeability is important for safety, operational consistency, and reduced installation risk. IEC 60061-2C:1972 matters because it supports a common basis for testing, quality assurance, and conformity assessment preparation around lamp-holder interfaces. Using a recognized reference helps reduce mismatch issues, improves engineering documentation, and strengthens regulatory preparation when products are reviewed against technical compliance expectations. It is especially useful where repeatable gauge-based checks are part of controlled testing workflows.

• Reference point for lampholder interface control and gauge-based verification
• Supports interchangeability checks for lamp caps and holders in lighting assemblies
• Useful for engineering documentation, inspection planning, and conformity assessment
• Helps reduce fit, safety, and compatibility risks during product evaluation
