IEC 61995-2:2025

IEC 61995-2:2025 Overview

IEC 61995-2:2025 is the second edition of the International Electrotechnical Commission (IEC) standard specifying devices for the connection of luminaires intended for household and similar purposes. It complements IEC 61995-1:2025 by defining the standard sheets for interface design of devices for connecting fixed luminaires operating at 250 V AC, 6 A. This standard replaces the first edition published in 2009 along with Amendment 1:2016 and introduces a technical revision aligning with the updated IEC 61995-1.

By standardizing the dimensions, retention mechanisms, and key mechanical features, IEC 61995-2 ensures interoperability and safety of devices such as DCL (Device for Connection of Luminaires) plugs and outlets. It applies to 2-pole plus earth devices designed for flush mounting in ceilings or walls to facilitate secure and easy luminaire installation.

Key Topics

• Scope and Application
  IEC 61995-2 covers DCL connection devices (plugs and outlets) for fixed luminaires in household environments, rated at 250 V AC and 6 A. It defines the interface design via detailed standard sheets ensuring mechanical compatibility.

• Standard Sheets Included

  • Standard sheet 1-1: DCL Outlet (6 A, 250 V AC, 2 poles + earth)
  • Standard sheet 1-2: DCL Plug (6 A, 250 V AC, 2 poles + earth)
  • Standard sheet 1-3: DCL Plug (6 A, 250 V AC, 2 poles without earth)
  • Standard sheet 1-4: Gauge for functional testing of the DCL plug

• Technical Changes in 2025 Edition

  • Withdrawal force requirements for plugs moved to IEC 61995-1
  • Alignment with the latest edition of IEC 61995-1 for consistency

• Mechanical Design and Testing
  The standard sheets specify essential dimensions, chamfering, pin design, resilience of retention mechanisms, and gauge testing methods to ensure secure connectivity, proper insertion, and permissible withdrawal forces.

Applications

IEC 61995-2:2025 is critical for manufacturers, designers, and installers involved with household lighting systems including:

• Flush-mounted ceiling luminaires
• Wall-fixed lighting installations in residential buildings
• Connection devices for household and similar environments requiring standardized and safe luminaire interfaces
• Quality assurance testing of plugs and sockets compatible with DCL technology

Compliance with IEC 61995-2 enables:

• Safe electrical connections minimizing hazards related to electrical overload and faulty connections
• Universal interoperability across compliant devices, helping reduce installation errors and maintenance issues
• Design optimization meeting internationally recognized dimensional and mechanical requirements
• Simplified installation processes, lowering labor time and costs for electricians and builders
