SIST EN 60061-2:1999/A25:2003

Overview

EN 60061-2:1993/A25:2002 is the European adoption of Amendment A25 to IEC 60061‑2, the international standard that covers lampholders - the parts of lighting equipment that receive and support lamp caps. The amendment (A25:2002) updates requirements related to the control of interchangeability and safety of lampholders and associated gauges. National adoptions (for example SIST EN 60061‑2:1999/A25:2003) reflect this change in local standards catalogs. To view the full, updated series you must subscribe to the IEC 60061 Database.

Key Topics

This standard amendment addresses technical and safety aspects essential to lampholders, including:

• Interchangeability control - ensuring lampholders accept specified lamp caps and permit correct mechanical and electrical fit.
• Dimensional gauges - use of gauges and measurement methods to verify lampholder and lamp cap compatibility.
• Design and construction principles - baseline requirements for lampholder geometry and materials to maintain safe operation.
• Safety and performance tests - mechanical, thermal and electrical verification procedures to confirm safe use under expected conditions.
• Marking and identification - guidance on identifying lampholder types and ratings to support correct replacement and installation. Note: This summary highlights topic areas; consult the IEC/EN text for exact test methods, tolerances and clause-level details.

Applications

Who uses EN 60061‑2 and why:

• Lighting manufacturers - design and validate lampholders to be interchangeable and compliant with international safety norms.
• Test laboratories and certification bodies - perform standardized tests and compliance assessments for product approval.
• Specifiers and procurement teams - ensure purchased lampholders meet interchangeability and safety requirements for fixtures and replacements.
• Installers and maintenance engineers - verify correct lamp/holder combinations to prevent misuse and safety hazards.
• Regulators and standards committees - reference the standard when creating product safety regulations or national adoptions.
