SIST EN 60061-1:1999/A2:1999

Overview

EN 60061-1:1993/A2:1995 (adopted as SIST EN 60061-1:1999/A2:1999) is a European/CLC standard covering lamp caps - the interface components of electric lamps that engage with lamp holders - and the use of gauges to control interchangeability and safety. The document is part of the IEC/EN 60061 series and is intended to ensure that lamp caps fit correctly, operate safely, and are consistently identified across manufacturers and markets.

Key Topics

This part (Part 1: Lamp caps) addresses the fundamental requirements needed to achieve safe and interchangeable lamp cap designs. Key technical topics typically covered include:

• Scope and definitions related to lamp caps, holders and gauges
• Designation and marking practices to identify cap types and ensure correct use
• Dimensional requirements and tolerances to ensure mechanical interchangeability with corresponding lamp holders (checked using gauges)
• Mechanical and electrical safety considerations to prevent incorrect insertion, accidental contact, or arcing
• Gauges and control methods used to verify dimensions and fit for quality control and compliance
• Inspection and test principles to assess conformity with the standard (visual checks, fit tests using gauges, mechanical endurance)
• Reference classification information (ICS 29.140.10 for lamp caps and holders)

(Note: this summary lists topic areas; consult the official standard for exact measurements, test procedures and normative clauses.)

Applications

EN 60061-1 is essential for stakeholders involved in lighting product development, production and safety compliance:

• Lamp and luminaire manufacturers - design and verify lamp caps for interchangeability and compliance
• Quality control and testing laboratories - use gauges and tests specified to confirm conformance
• Purchasing and procurement teams - specify cap types and ensure compatibility across suppliers
• Regulatory bodies and certification agencies - reference the standard for product approvals and market surveillance
• Electrical installers and lighting designers - rely on standardized cap types for safe system integration

Using a harmonized standard helps reduce product failures, enhances safety, and simplifies international trade of lighting components.
