Overview

EN IEC 62868-2-4:2025 (adopted by CLC/CENELEC) defines the safety requirements for rigid OLED tiles and panels intended for general indoor lighting on supplies up to 120 V ripple-free DC. It is Part 2-4 in the IEC 62868 series and complements the Part 1 general requirements. The document covers construction, marking, electrical safety, mechanical strength and other particular requirements specific to rigid OLED tiles and panels used in luminaires and lighting systems.

Key topics and requirements

This standard addresses practical safety and testing topics for rigid OLED light sources, including:

• Scope and definitions
  • Clear definitions for OLED tile and OLED panel and related terms (aligned with IEC 62504 and IEC TS 62972).
• Marking and information
  • Requirements for content, location, durability and legibility of markings and safety information.
• Construction and mechanical integrity
  • Rules for mechanical strength, vibration testing and resistance to dust, solid objects and moisture.
• Electrical safety
  • Insulation resistance and electric strength requirements, creepage distances and clearances to prevent shock and short circuits.
• Fault and thermal conditions
  • Requirements for behaviour under fault conditions, thermal stress and resistance to heat.
• Fire and corrosion resistance
  • Resistance to flame, ignition and corrosion of live parts and connections.
• Photobiological safety
  • Measures to address eye and skin exposure risks from OLED emissions.
• Terminals, earthing and connections
  • Requirements for terminals, protective earthing provisions, screws and current-carrying parts.
• Tests and informative annexes
  • Test guidance (vibration, internal short-circuit assessment, electric strength) and Annex A illustrating typical OLED tile/panel construction.

Applications and who uses this standard

EN IEC 62868-2-4:2025 is intended for manufacturers, test laboratories, product designers, lighting specifiers and regulatory bodies involved with:

• Design and certification of rigid OLED tiles and panels for indoor general lighting
• Product safety compliance and conformity assessment for LED/OLED lighting products
• Luminaire manufacturers integrating OLED panels into fixtures and ensuring compatibility with 120 V DC supplies
• Test houses performing electrical, mechanical and photobiological testing for market access
