Overview
EN ISO 9241-5:2024 - Ergonomics of human‑system interaction, Part 5: Workstation layout and postural requirements - specifies ergonomic guiding principles for the design, procurement and use of workstation equipment for interactive systems with visual displays. Adopted by CEN as EN ISO 9241-5:2024, this updated part of the ISO 9241 series replaces earlier editions and focuses on minimizing health risks and improving comfort and performance through appropriate workstation layout and postural design.
Key topics and technical requirements
The standard addresses practical, technical aspects of workstation ergonomics without prescribing specific proprietary solutions. Major topics include:
- Guiding principles: versatility, flexibility, fit, postural change, maintainability/adaptability and user information.
- Postural requirements: design reference postures; recommendations for sitting, standing, sit‑stand and semi‑standing postures.
- Ease of adjustment: adjustability of surfaces, chairs and accessories to accommodate a range of users (anthropometry).
- Support surfaces: clearances under worksurfaces, finishes, contact energy loss, stability and safety.
- Viewing geometry: recommended viewing distances and angles of view for visual displays.
- Work chair specifications: fit parameters, dynamic seating, back and arm support recommendations.
- Additional support elements: document holders, footrests, wrist/forearm supports, monitor arms and layout implications.
- Workspace layout: cable management, placement of equipment, and spatial organization within the workspace.
- Conformity and measurement: requirements and measurement methods for key dimensions and performance.
- Annex A: anthropometric data needed for workstation design and selection.
Practical applications and users
EN ISO 9241-5:2024 is directly applicable where interactive visual display systems are used. Typical users include:
- Product and furniture designers developing desks, chairs, monitor arms and accessories.
- Ergonomists and occupational health professionals specifying safe postures and layouts.
- Procurement officers and facility managers setting requirements for office and control‑room furniture.
- Manufacturers of IT peripheral equipment and system integrators who must ensure compatibility with ergonomic workstations.
- Regulatory and standards writers coordinating technical design standards for workplaces.
Use this standard to guide design choices, procurement specifications, workplace assessments and to ensure compliance with ergonomic best practices for visual display work.
