Overview - ISO/TR 7250-2:2024 (Basic human body measurements - Part 2)
ISO/TR 7250-2:2024 is a Technical Report that compiles statistical summaries of anthropometric (human body) measurements collected in national populations of ISO member bodies. It provides standardized, documented statistical outputs for working-age populations measured according to ISO 7250-1, with database background information prepared in line with ISO 15535. The report also describes the measurement and statistical preparation processes, and includes national datasets and informative annexes on comparability and scan-derived data.
Key topics and technical requirements
- Measurement protocol: Body dimensions must be measured as defined in ISO 7250-1 to ensure comparability.
- Database quality: Databases used for statistics are expected to conform to ISO 15535 requirements for anthropometric data collection and documentation.
- Statistical procedures:
- Data editing and cleaning
- Reporting of central tendencies (e.g., mean, P50) and dispersion (standard deviation, percentiles)
- Handling minima, maxima and marking values likely to be in error
- Population stratification:
- By sex, age groups (country-defined working age), and representative body forms
- Guidance on sampling method and representativeness
- Accuracy and reliability:
- Documentation of measurer skill and measurement conditions
- Treatment of 3D scan-derived data and verification against manual methods (referencing ISO 20685-1:2018)
- Reporting procedure:
- One data set submission per member body
- Background information: measurement time period, location, demographic context, publications, and secular change considerations
- Annexes:
- Allowable differences between ISO 7250-1 and other methods
- Scan-derived datasets not evaluated for comparability
Practical applications and users
ISO/TR 7250-2:2024 is intended for anyone who requires reliable anthropometric statistics for design and safety decisions:
- Ergonomists and human factors engineers using anthropometric percentiles for workspace, control layout, and reach envelopes
- Product designers and manufacturers of furniture, consumer goods, clothing, personal protective equipment (PPE), vehicles and seating
- Standards developers and regulatory bodies referencing population-specific dimensions in product standards
- Researchers and demographers studying secular change and population body-shape trends
- Occupational health and safety professionals tailoring equipment and environments to national working-age populations
