SIST EN 60061-2:1999

Overview

EN 60061-2:1993 (consolidated edition valid 1996‑12‑31) is a European standard published under the CLC system that covers lampholders (Part 2) and associated gauges used to control interchangeability and safety of lamp caps and holders. The consolidated edition incorporates the third edition (1969) and multiple supplements, and has been adopted in national variants (e.g., SIST EN 60061-2:1999). This standard defines the requirements and means of verification to ensure lampholders are mechanically and electrically compatible with specified lamp caps and are safe for intended use.

Key topics and requirements

The standard addresses technical aspects necessary to guarantee safe, interchangeable lampholder designs and includes guidance on:

• Dimensional and mechanical requirements for lampholders to ensure interchangeability with corresponding lamp caps.
• Gauges and control methods for verifying correct fits and tolerances between lamp caps and holders.
• Electrical characteristics and performance expectations for contacts, insulation, and current‑carrying parts.
• Safety considerations such as prevention of accidental contact, secure retention of lamps, and resistance to mechanical stress.
• Marking and identification to enable correct selection and safe use of lampholders.
• Verification and testing procedures to confirm conformity (mechanical fit checks, functional tests, and durability checks) - implemented via calibrated gauges and test methods described or referenced in the document.

Note: EN 60061-2 provides normative requirements and measurement practices; specific numerical values, test parameters and tolerance tables are contained in the standard text and its supplements.

Applications

EN 60061-2 is practical for:

• Designing and manufacturing lampholders that must be interchangeable with standardized lamp caps.
• Developing and maintaining quality control processes using gauges to check dimensional conformity.
• Preparing conformity documentation for product assessment and CE or national market compliance.
• Specifying components for lighting fixtures, replacement sockets, and electrical accessories where safe mating with lamps is critical.
• Informing procurement and specification writing for lighting systems in commercial, industrial and residential projects.

Who uses this standard

• Lighting and electrical component manufacturers
• Product design engineers and industrial designers
• Test laboratories and quality assurance teams
• Regulatory bodies, certification bodies and market surveillance authorities
• Procurement specialists and technical buyers in lighting and electrical industries
