Overview
ISO 11064-4:2013 - Ergonomic design of control centres - Part 4: Layout and dimensions of workstations provides ergonomic principles, recommendations and requirements for designing control centre workstations. The standard focuses on layout and dimensions for primarily seated, visual-display-based workstations (VDTs), while also addressing standing workstations. It is intended for control rooms used in transportation, process control, security, emergency services and other monitoring/dispatch environments where flat-display screens and operator interaction are central.
Key topics and technical requirements
- Anthropometry and user population: Workstation design shall accommodate the 5th to 95th percentiles of the intended user population, taking account of gender, age, ethnicity and disabilities. Specific anthropometric considerations include reach envelopes and clearances.
- Task-driven layout: Start with task analysis to identify information and control needs, group task zones, and arrange displays, controls and documentation accordingly (see the standard’s recommended design steps).
- Visual and auditory tasks: Requirements address viewing geometry (line-of-sight, cone of fixation, visual angle, nearpoint), legibility of information, and placement of auditory equipment.
- Working postures: Guidance for seated and standing postures, operator reach, and postural comfort to reduce fatigue and error.
- Layout requirements and dimensions: Clauses cover general layout principles, reach zones, workspace clearances and dimensioning rules for seated and standing control workstations (including elevation and plan considerations).
- Maintainability and access: Considerations for access to wiring, replacement parts and servicing without disrupting operator tasks.
- Normative references: Integrates related ergonomics standards such as ISO 7250-1 (anthropometric definitions) and ISO 9241 series (human-system interaction).
Practical applications and who uses it
- Control room and workstation designers planning layouts and furniture for process control rooms, traffic management centres, security monitoring suites and emergency dispatch centres.
- Ergonomists and human factors specialists assessing operator reach, visual access and posture.
- Facilities planners, safety engineers and HCI/UI designers specifying mounting heights, display arrangement and control placement.
- Manufacturers of control-room furniture, consoles and display systems seeking compliance with ergonomic best practice.
Practical benefits include improved operator comfort, reduced error rates, better information access, and standardized design bases for procurement and compliance.
