Overview
EN ISO 9241-300:2008 (ISO 9241-300:2008) is the introductory part of the ISO 9241 “300” subseries on ergonomics of human–system interaction for electronic visual displays. It explains the subseries’ modular structure, scope and purpose: to establish performance‑based display ergonomics requirements and provide test methods and metrology for design evaluation and conformance. The standard targets effective and comfortable viewing for users with normal or adjusted‑to‑normal eyesight and is applicable across diverse tasks and work environments.
Key topics and requirements
- Modular structure: Introduces how the subseries is organized so new technologies, tasks and environments can be covered without reworking the core guidance.
- Performance specifications: Emphasizes requirements stated as measurable performance criteria rather than prescriptive design rules.
- Conformance framework: Directs use of ISO 9241-307 for compliance routes and links testing methods to appropriate parts of the subseries.
- Test methods and metrology: References three primary testing approaches:
- ISO 9241-304 - user performance (usability) laboratory test methods
- ISO 9241-305 - optical and electrical laboratory test methods
- ISO 9241-306 - field assessment methods for workplace evaluation
- Terminology and definitions: Points to ISO 9241-302 for consistent terms used across the subseries.
- Integrated vs modular products: Discusses when display systems or modules (monitors, graphics adapters, software) can be type‑tested individually and when combined or field testing is required.
- Work environment considerations: Recognizes environmental factors (lighting, viewing distance, tasks) that affect human–display interaction and testing strategies.
Applications and who uses it
EN ISO 9241-300 is used by:
- Display manufacturers - to design ergonomic displays and provide conformance test data.
- Ergonomists and human factors engineers - to evaluate visual ergonomics and specify requirements.
- Test laboratories (optical and usability labs) - to apply ISO/IEC 17025‑compatible methods (ISO 9241-304/305).
- Procurement and compliance officers - to define ergonomic acceptance criteria for purchased equipment.
- Workplace designers and safety managers - to assess displays in situ using field methods (ISO 9241-306).
Practical uses include product design validation, usability testing, procurement specifications, workplace assessments, and regulatory/compliance reporting.
