Overview
The EN 60061-2:1993/A57:2021 standard, published by the European Committee for Electrotechnical Standardization (CENELEC), focuses on lamp caps and holders, specifically Part 2 which deals with lampholders. This amendment A57 updates the existing EN 60061-2:1993 standard to ensure continued interchangeability and safety of lampholders in electrical lighting applications. Based on the IEC 60061-2:1969/A57:2020 international standard, it provides unified guidelines for design, construction, and testing of lampholders used across various lighting fixtures.
Key Topics
Interchangeability and Safety Controls
The document specifies gauges and criteria to control the interchangeability of lamp caps and lampholders, ensuring compatibility and preventing issues such as improper connections or safety hazards.Design and Construction Requirements
Detailed requirements for lampholders include thread positions, contact arrangements, and mechanical specifications to facilitate secure lamp fitting and electrical connection.Types of Lampholders Covered
This standard encompasses a wide range of lampholder types including but not limited to:- Bayonet lampholders (B22d, B15d, BAY15s)
- Edison screw lampholders (E11, E12, E26, E39)
- Prefocus lampholders (P28s, EP10)
- Recessed double-contact lampholders (R17d)
- Specialized lampholders for automotive and tubular lamps
- Various miniature and bi-pin lampholders (G4, GY9.5, GX5.3, etc.)
Testing Gauges for Compliance
Specific gauges for dimensions and fitment are provided, enabling manufacturers and inspectors to verify that lampholders comply with the interchangeability and safety requirements.Mounting Arrangements
The standard addresses installation aspects such as mounting distances for combined pairs of lampholders, which is important for products using multiple lamps within compact fixtures.
Applications
