Overview

EN 60061-2:1993/A52:2017 (IEC 60061-2:1969/A52:2017) is a harmonized European amendment for lampholders that forms Part 2 of the IEC 60061 series: “Lamp caps and holders together with gauges for the control of interchangeability and safety.” This amendment (A52, approved 2017) updates the lampholder sheets and national implementation timetable (latest implementation date 2018‑03‑20; conflicting standards withdrawal by 2020‑06‑20). The document provides standardized designation sheets and guidance to ensure mechanical interchangeability and safe use of lamp holders across markets.

Key topics and requirements

• Scope and purpose: Standardizes lampholder types and associated gauges used to check interchangeability and safety between lamps and holders.
• Designation sheets: Includes individual sheets for many common lampholders (examples shown in the amendment include E11, E12, E26, E39, B22d, BA15, G4, G5.3, GY5.3, G12, GX10q, GY10q, 2G13, 2G11 and many automotive and prefocus types).
• Dimensional and mounting guidance: Sheets and tables specify mounting distances, positions of threaded sleeves relative to central contacts, and other dimensional relationships needed for correct mating and safe operation.
• Design principles: Principles for lampholder design (mechanical interfaces, connector types and combined-pair mounting arrangements) to promote interchangeability.
• Gauges and control: References to the gauges used to verify compliance of caps and holders with the standardized dimensions.
• Safety and conformity: Emphasis on compatibility to prevent electrical or mechanical hazards; notes that patent rights may apply and national implementation rules govern use.

Applications and who uses it

This standard is practical for:

• Lamp and lampholder manufacturers - to design products that correctly mate with standardized caps and pass interchangeability checks.
• Luminaire designers and OEMs - to select compliant lampholders for fixtures and ensure safe operation.
• Test laboratories and certification bodies - to verify lampholders and gauges against IEC/EN requirements.
• Regulatory and compliance teams - to reference harmonized European requirements for market access.
• Procurement and specification writers - to define product requirements that ensure cross‑compatibility and safety.
• Maintenance engineers and electricians - as a technical reference when replacing or specifying holders and caps.

Related standards

• IEC 60061 (other parts) - the broader series covering lamp caps, holders and gauges.
• National adoptions of EN 60061-2 (CENELEC members) - for country‑level implementation and endorsement.

This amendment is essential for ensuring mechanical and electrical interchangeability of lampholders and for harmonizing safety verification using gauges across the lighting industry.
