Full title and description

ISO 10075-3:2004 — Ergonomic principles related to mental workload — Part 3: Principles and requirements concerning methods for measuring and assessing mental workload. This part sets out principles and minimum requirements for methods and instruments used to measure and assess mental workload, and provides guidance for choosing and applying appropriate assessment techniques.

Abstract

ISO 10075-3:2004 establishes principles and requirements for the measurement and assessment of mental workload, specifies requirements for measurement instruments, and gives guidance to help choose appropriate methods and improve communication among parties involved in mental-workload assessment. It is primarily intended for ergonomic and human‑factors specialists who design, evaluate or interpret workload measures.

General information

• Status: Published; the ISO record shows this edition confirmed following periodic review.
• Publication date: 2004 (ISO listing: August 2004 / Edition 1).
• Publisher: International Organization for Standardization (ISO). National/adopted versions are published by national bodies (for example BSI, SIS).
• ICS / categories: 13.180 — Ergonomics.
• Edition / version: Edition 1 (2004).
• Number of pages: ISO lists the core international document as 15 pages; some national/adopted versions (EN / BS adoptions) include front matter and annexes and are commonly listed with higher page counts (e.g., 22–26 pages in some national catalogues). Users should check the specific national edition for exact pagination.

Scope

Part 3 specifies principles and requirements for procedures used to measure and assess mental workload. It covers characteristics that measurement methods should have, requirements for instruments and data collection, and guidance for selecting and applying methods in workplace and research contexts. It is aimed at professionals with relevant training who are responsible for developing, evaluating or using workload assessment methods.

Key topics and requirements

• Principles for valid and reliable measurement of mental workload (construct clarity, context sensitivity, repeatability).
• Requirements for measurement instruments (documentation, calibration where applicable, clarity of scales and items, usability).
• Guidance on selecting appropriate methods (objective physiological measures, performance measures, subjective rating scales) and combining methods when needed.
• Recommendations for data collection, reporting and interpretation to improve comparability and communication between stakeholders.
• Considerations of measurement validity, reliability, and ethical/occupational-health aspects when assessing mental workload.

Typical use and users

Primary users are ergonomists, human factors specialists, occupational health professionals, psychologists and researchers involved in workplace design, safety assessments, human‑machine interaction and performance evaluation. Typical uses include selecting or evaluating workload assessment tools, designing measurement protocols for studies or workplace assessments, and interpreting workload data to inform design or organisational decisions.

Related standards

ISO 10075-3 is part of the ISO 10075 series on mental workload; related documents include ISO 10075-1 (General issues, concepts, terms and definitions — published 2017) and the design‑principles part ISO 10075-2 (earlier editions from 1996, with a revised edition appearing in 2024). National adoptions and EN/BS versions (EN ISO / BS EN) exist and may add national forewords or annexes.

FAQ

Q: What is this standard?

A: ISO 10075-3:2004 is the third part of the ISO 10075 series; it defines principles and requirements for methods used to measure and assess mental workload in ergonomics and human‑factors practice.

Q: What does it cover?

A: It covers the characteristics of appropriate measurement methods and instruments, guidance for choosing and applying methods (subjective, performance-based and physiological approaches), and requirements for documentation, reporting and interpretation to ensure valid and reliable assessments.

Q: Who typically uses it?

A: Ergonomists, human factors engineers, occupational health specialists, psychologists, designers and researchers who need standardised guidance on measuring and interpreting mental workload.

Q: Is it current or superseded?

A: ISO lists the 2004 edition (Edition 1) as the published document; the ISO bibliographic record indicates periodic review and confirmation activity. Users should verify the status of national adoptions and more recent related parts (for example ISO 10075-1:2017 and revisions to Part 2) for the complete, current framework.

Q: Is it part of a series?

A: Yes — ISO 10075 is a multi‑part series on ergonomic principles related to mental workload (notably Part 1: concepts and definitions; Part 2: design principles; Part 3: measurement and assessment methods).

Q: What are the key keywords?

A: Mental workload, workload measurement, ergonomics, assessment methods, subjective ratings, physiological measures, performance measures, validity, reliability.
