Full title and description

STB VDE 0750-241-1 / DIN EN 62366-1:2021-08 — Medical devices — Part 1: Application of usability engineering to medical devices. This document provides requirements for applying a usability-engineering process to medical devices and their associated software to ensure that user interactions are safe, effective and suited to the intended use and user population.

Abstract

This standard specifies a usability-engineering process that medical device manufacturers must follow to identify, analyse and control use-related risks that arise from the user interface. It covers identification of user characteristics and use environments, specification of user-interface requirements, formative and summative evaluation activities (including usability validation), and documentation and traceability requirements that integrate usability with overall device risk management.

Scope

The scope covers requirements for the application of a usability-engineering process to medical devices (including standalone software and software as a medical device) in order to reduce use-related hazards. It applies to manufacturers developing new devices and to organizations implementing changes where the user interface or intended use is affected. The standard focuses on identifying use scenarios and user profiles, specifying user-interface requirements, performing formative and summative usability evaluations, and documenting the usability process in the technical file.

Key topics and requirements

• Establishing a usability-engineering plan and usability process integrated with device risk management.
• Defining user profiles, intended use environments and use scenarios that reflect real-world conditions.
• Identifying use-related hazards and hazardous situations linked to the user interface.
• Specifying usability and user-interface requirements and tracing them to design and risk controls.
• Conducting formative (iterative) evaluations during design to detect and mitigate usability issues early.
• Performing summative (validation) testing to confirm effectiveness of usability risk controls for intended users and use environments.
• Documentation and reporting requirements for usability activities and integration with the technical file/clinical evaluation dossier.
• Guidance on test methods, sample sizes, data collection, and interpretation of usability test results.
• Recommendations for post-market monitoring of usability issues and updating the usability process after incidents or changes.

Typical use and users

Primary users of this standard are medical device manufacturers, human factors/usability engineers, software developers for medical applications, quality and regulatory affairs professionals, notified bodies and test laboratories. It is used to design safer user interfaces, prepare usability documentation for regulatory submissions, develop test protocols and perform validation testing to demonstrate that use-related risks are adequately controlled.

FAQ

Q: What is this standard?

A: It is the German/European adoption (VDE/DIN) of the IEC/EN standard for applying usability engineering to medical devices — setting requirements for how manufacturers identify and control use-related risks arising from device user interfaces.

Q: What does it cover?

A: It covers the full usability-engineering lifecycle: planning, user and use analysis, requirements specification, formative evaluation during design, summative (validation) testing, documentation and integration with device risk management and regulatory documentation.

Q: Who typically uses it?

A: Human factors and usability engineers, device designers, software developers, quality and regulatory teams at medical device manufacturers, as well as conformity assessment bodies and usability test laboratories.

Q: Is it current or superseded?

A: The edition referenced is dated August 2021. Manufacturers and assessors should confirm with the national standards body (DIN/VDE) or the publisher for any amendments or newer editions to ensure compliance with the latest regulatory and harmonization status.
