Overview
IEC TR 63340-2:2025 - "Electronic displays for special applications - Part 2: Elevator and escalator" is a Technical Report published by the IEC that provides general information and guidance for the standardization of electronic displays used in elevators and escalators. It introduces the IEC 63340 series, summarizes current display technologies and market situations, classifies display locations and use-cases, and outlines candidate items and procedures for future normative standards development.
Key topics and technical themes
The report addresses practical and technical aspects relevant to elevator and escalator displays, including:
- Technology overview and market classification
- Types of displays (LCD, LED, OLED, STN, etc.) and their roles in control panels, car doors, ceilings, walls, floors, escalator panels and step risers.
- Traditional and new display applications
- From status indicators and floor indicators to interactive aerial displays and integrated car-wall signage.
- Performance and reliability issues
- Optical performance under varied ambient luminance, ambient contrast ratio (ACR), light decay, colour and luminance non‑uniformity, surface reflections, and mechanical durability.
- Environmental and operational considerations
- Effects of extreme temperatures, dynamic stress (vibration, shock), electromagnetic interference (EMI/EMC) and long-term light decay.
- Standardization candidates and specification guidance
- Suggested specification tables and essential/common conditions (e.g., standard illumination, test conditions) are provided in informative annexes to support future normative standards.
- Stakeholders and standardization landscape
- Roles of stakeholders (manufacturers, OEMs, building designers, lift/escalator associations) and related SDOs such as ISO/TC 178, CEN/TC 10, CEA, ASME, CSA and national committees.
Practical applications - who uses this TR
IEC TR 63340-2 is useful for:
- Elevator and escalator OEMs and component manufacturers designing embedded display units.
- System integrators and installers specifying display performance for retrofit or new builds.
- Architects and building owners coordinating architectural displays with lift/escalator interfaces.
- Standards developers and test laboratories preparing test methods and normative requirements.
- Certification bodies and safety assessors evaluating display reliability, EMC and optical safety in vertical transport environments.
Related standards and next steps
Relevant standards and series referenced include ISO 8100, IEC 62368-1, and CEA documents. The TR is explicitly positioned as guidance to help develop future normative standards - it provides candidate items, specification tables and measurement setups (Annex A) to accelerate harmonized standardization for elevator and escalator displays.
