BS EN 62366-1-2015 + A1-2020 PDF

Full title and description

STB BS EN 62366-1:2015 + A1:2020 — Medical devices — Part 1: Application of usability engineering to medical devices. This is the British/European adoption of IEC 62366-1:2015 together with Amendment 1 (2020), providing a consolidated usability‑engineering (human factors) process for medical‑device user interfaces aimed at identifying and mitigating use‑related safety risks.

Abstract

This standard specifies a usability‑engineering process manufacturers should follow to analyse, specify, develop and evaluate the usability of a medical device user interface as it relates to safety. It focuses on identifying use errors and reducing use‑related risks in normal use, and strengthens links to risk management (ISO 14971). Amendment A1:2020 corrects and clarifies issues in the 2015 text without fundamentally changing the prescribed process.

Scope

Applies to the usability engineering of medical devices (including device software and many in‑vitro diagnostic devices) where the user interface may affect safety. The standard describes processes to: define intended use and user profile; identify use‑related hazards; integrate usability activities with risk management (see ISO 14971); perform formative and summative usability evaluations; and document usability validation to demonstrate that use‑related risks have been addressed. It is intended for manufacturers as part of design and verification/validation evidence.

Key topics and requirements

• Usability‑engineering process: planning, user/profile analysis, use‑scenario analysis, hazard identification and risk control for user interfaces.
• Integration with risk management: explicit linkage to ISO 14971 (updated reference to ISO 14971:2019 in the amendment).
• Specification of user interface requirements and rationale for design decisions (traceability into risk controls).
• Formative (iterative) usability studies during development and summative (validation) studies to show residual risk is acceptable.
• Consideration of intended users, use environment, training, labeling and instructions for use as part of the usability assessment.
• Documentation and reporting requirements: usability engineering file and evidence to support regulatory submissions and conformity assessment.

Typical use and users

Primary users are medical‑device manufacturers, product design and quality teams, human factors/usability engineers, regulatory and clinical affairs specialists, notified bodies and regulators reviewing conformity evidence, and consultants who prepare usability engineering files and validation reports. The standard is used to structure human factors activities required for device design, verification/validation and regulatory submissions.

Related standards

Commonly used together with: ISO 14971 (risk management for medical devices / EN ISO 14971), IEC 62366‑2 (related parts as applicable), IEC 60601 series (electrical safety and essential performance), ISO/TR 24971 (guidance on ISO 14971), and national/adopted versions of the IEC/EN texts; FDA and other regulator human‑factors guidance documents are also relevant for regulatory submissions.

FAQ

Q: What is this standard?

A: It is the British/European adoption of IEC 62366‑1:2015 with Amendment 1 (2020). It defines a usability‑engineering process for medical‑device user interfaces to reduce use‑related safety risks.

Q: What does it cover?

A: It covers the process for analysing, specifying, developing and evaluating the usability of medical device user interfaces as they relate to safety — including user analysis, use scenarios, hazard identification, integration with risk management, formative and summative testing, and required documentation.

Q: Who typically uses it?

A: Medical device manufacturers, human factors/usability engineers, clinical and regulatory teams, notified bodies and consultants preparing design validation and conformity evidence.

Q: Is it current or superseded?

A: The A1:2020 amendment is the current amendment to IEC/EN 62366‑1:2015 and is implemented in national adoptions such as BS EN 62366‑1:2015+A1:2020 (published in August–September 2020). It supersedes previous 2015‑only adoptions by incorporating the 2020 corrections and clarifications.

Q: Is it part of a series?

A: Yes — it is Part 1 of the IEC/EN 62366 series (usability engineering). Part 1 defines the process; related work on Part 2 (where applicable) and other human‑factors guidance should be consulted alongside ISO 14971 and relevant regional regulatory guidance.

Q: What are the key keywords?

A: Usability engineering, human factors, user interface, use error, risk management, usability validation, formative testing, summative testing.
