ISO 9241-300:2008

Overview

ISO 9241-300:2008 - Ergonomics of human‑system interaction: Introduction to electronic visual display requirements - provides the framing and structure for the ISO 9241 “300” subseries on display ergonomics. It defines the purpose and modular layout of the subseries, sets out the intent to express requirements as performance specifications, and explains how test methods and metrology are used to produce conformance measurements and criteria for electronic visual displays used across a wide range of tasks and work environments.

Key topics and technical requirements

• Modular structure: ISO 9241-300 introduces and links the related parts (terminology, requirements, user tests, optical lab methods, field methods, analysis and compliance).
• Performance specifications: Requirements are stated in terms of human performance and comfortable viewing for users with normal or adjusted‑to‑normal eyesight rather than prescriptive design features.
• Test methods and metrology: Conformance relies on specified test methods (ISO 9241-304, -305, -306) and analysis/compliance routes (ISO 9241-307) to yield measurable criteria.
• Conformance approach: Compliance is achieved using the appropriate analysis/compliance method per ISO 9241-307, with fallback guidance from ISO 9241-303 when no direct compliance method exists.
• Integrated vs. modular products: Guidance on when modules (monitor, graphics card, software) can be type-tested independently and when full system or field assessment is required.
• Environment considerations: The standard recognizes that work environments (office, medical, control room, mobile, industrial) affect display ergonomics and testing needs.

Applications and who uses it

ISO 9241-300 is practical for:

• Display manufacturers and hardware designers developing monitors, mobile displays, medical imaging screens, ATMs and embedded displays.
• Usability and human factors professionals conducting user-performance testing and ergonomic assessments.
• Test laboratories performing optical and user-based conformance testing per ISO/IEC 17025 quality criteria.
• Procurement and QA teams specifying and verifying ergonomic display performance in workstations and control systems.
• Systems integrators and product managers coordinating modular systems (PC + monitor + software) where combined behavior affects visual ergonomics. Typical applications include design evaluation, lab validation of image quality and flicker, field assessments in real workplaces, and compliance documentation for safety, usability and occupational health.
