SIST EN 60061-1:1999/A26:2002

Overview

EN 60061-1:1993/A26:2001 is a European adoption of IEC requirements covering lamp caps (light bulb bases) and the gauges used to control their interchangeability and safety. Published as part of the IEC/EN 60061 series and incorporated by CLC (published in the Slovenian edition as SIST EN 60061-1:1999/A26:2002), this amendment (A26) updates Part 1 of the series. The standard defines the general principles and requirements that ensure lamp caps are mechanically and electrically compatible and safe for use with corresponding lamp holders.

Key Topics and Requirements

The document focuses on technical and safety aspects that support reliable interchangeability of lamps and holders. Key topics include:

• Scope and definitions relevant to lamp caps and their intended use
• Dimensional requirements and tolerances to ensure mechanical fit between caps and holders
• Electrical safety considerations for secure contact, insulation, and prevention of hazardous conditions
• Material and construction guidance for durability, heat resistance, and electrical isolation
• Test methods and gauges used to verify compliance with interchangeability and safety criteria
• Marking and identification to facilitate correct specification, replacement, and traceability
• Conformity and inspection practices for manufacturers and test laboratories

The standard sets performance-oriented requirements and prescribes the use of gauges and tests to verify that lamp caps will operate safely and interchangeably with corresponding holders.

Applications

EN 60061-1:1993/A26:2001 is practical for stakeholders across the lighting value chain:

• Lamp and lamp cap manufacturers - to design and produce bases that meet accepted interchangeability and safety criteria
• Lamp holder and fixture manufacturers - to ensure compatibility with standard lamp caps
• Testing laboratories and conformity assessors - to apply gauges and tests for certification and quality control
• Electrical installers, specifiers and procurement professionals - to select compliant products and reduce compatibility risks
• Regulatory and standards bodies - for alignment with regional safety and interoperability requirements
