IEC 62366-1-2020 PDF

Full title and description

St IEC 62366-1-2020 — Medical devices — Part 1: Application of usability engineering to medical devices. This publication is the IEC/ISO international standard that defines a usability engineering (human factors) process for manufacturers to analyse, specify, develop and evaluate the usability of medical devices as it relates to safety; the 2015 base edition is consolidated with Amendment 1 published in 2020.

Abstract

IEC 62366-1 specifies a structured process for assessing and mitigating risks associated with correct use and use errors of medical devices by addressing user interface safety. The standard focuses on normal use and use-related hazards, links usability engineering to medical device risk management practices (notably ISO 14971), and provides requirements that manufacturers can apply to identify, evaluate and control use-related risks. The 2015 edition with the 2020 amendment updates and streamlines earlier guidance and strengthens ties to risk management methods.

Scope

IEC 62366-1 establishes requirements for a manufacturer’s usability engineering process to identify and mitigate safety-related use errors and use-related hazards in medical devices. It applies to device user interfaces (including software interfaces) and describes how usability engineering should be integrated with device risk management. The standard addresses normal/expected use and the reduction of use errors that could lead to hazardous situations; it is not intended to comprehensively address abnormal or intentionally misuse scenarios.

Key topics and requirements

• Establishing a usability engineering process tied to device safety objectives and overall risk management.
• Identification and analysis of intended users, use environments, use scenarios and use-related hazards.
• Specification of user interface safety requirements and design inputs derived from use-related risk analysis.
• Iterative formative and summative evaluation of user interfaces (including use-error analysis and user testing where appropriate).
• Documentation and traceability between usability activities, risk control measures and verification/validation evidence.
• Integration and alignment with device risk management (ISO 14971) and related regulatory expectations for human factors/usability.

Typical use and users

Manufacturers of medical devices, human factors/usability engineers, design and development teams, regulatory affairs professionals, clinical safety specialists, and quality managers use this standard to design, evaluate and document user interfaces with respect to safety. Notified bodies, conformity assessment bodies and regulators commonly reference IEC 62366-1 when assessing human factors compliance for pre-market submissions and post-market assessments.

Related standards

IEC 62366-1 is closely related to IEC 62366-2 (tutorial and guidance material), the withdrawn IEC 62366:2007 and its amendment, and to ISO 14971 (application of risk management to medical devices). Other related guidance may include regional regulatory human factors guidance documents that reference IEC 62366-1.

FAQ

Q: What is this standard?

A: IEC 62366-1 is an international standard that specifies the usability engineering process manufacturers must use to analyse, develop and evaluate medical device user interfaces as they relate to safety. The 2015 edition is in force and was amended in 2020; consolidated editions incorporate that amendment.

Q: What does it cover?

A: It covers the requirements for identifying user-related hazards, specifying user interface safety requirements, performing iterative formative and summative usability evaluations, and documenting how usability activities reduce use-related risks. It is intended to be applied alongside device risk management processes.

Q: Who typically uses it?

A: Medical device manufacturers, human factors engineers, R&D/design teams, clinical and regulatory personnel, and conformity assessment bodies use IEC 62366-1 to design and assess safe user interfaces and to prepare regulatory submissions addressing human factors.

Q: Is it current or superseded?

A: The base edition is IEC 62366-1:2015 and it was amended by IEC 62366-1:2015/Amd 1:2020; consolidated versions incorporating the amendment are available and the standard was confirmed in subsequent reviews. Check the IEC/ISO catalog for the latest status if you need absolute current confirmation.

Q: Is it part of a series?

A: Yes — Part 1 (requirements) is complemented by IEC 62366-2, which provides tutorial material and more detailed guidance on methods and implementation. The Part 1/Part 2 structure replaces the earlier single-part IEC 62366:2007.

Q: What are the key keywords?

A: Usability engineering, human factors, user interface safety, use error, medical device risk management, formative/summative evaluation, ISO 14971.
