IEC 62304-2015 PDF

Full title and description

IEC 62304:2006 with Amendment 1 (2015) — Medical device software — Software life cycle processes. This publication is the internationally recognised standard that defines life‑cycle processes, activities and tasks for the safe development and maintenance of software that is a medical device or that is embedded in a medical device.

Abstract

IEC 62304 specifies the software life‑cycle processes required for the safe design, development, maintenance and retirement of medical device software. The 2015 amendment (A1) clarifies software safety classification and adds requirements addressing legacy software and related risk and maintenance considerations. Together the base standard and amendment establish a common framework of development, verification, validation, configuration management, problem resolution and maintenance activities intended to reduce software‑related hazards.

Scope

IEC 62304 defines the life‑cycle processes for medical device software: development, maintenance, risk management interfaces, verification and validation, configuration management, problem resolution and software release. The standard applies when software is itself a medical device, is embedded in a medical device, or is a component of a medical device system; the 2015 amendment extends/clarifies requirements for legacy software and software safety classification. The objective is to ensure that software does not introduce unacceptable risk to patients or users through a structured, auditable lifecycle approach.

Key topics and requirements

• Software safety classification (risk‑based classes A/B/C) and associated process rigor.
• Defined software life‑cycle processes: development planning, requirements, design, implementation, integration, verification and validation.
• Maintenance processes, including handling of legacy software and modifications (amendment emphasis).
• Configuration management and change control.
• Problem and incident resolution (including post‑market software problem handling and corrective actions).
• Traceability between requirements, design, implementation and verification artifacts.
• Integration of risk management activities (interface to ISO 14971) for hazard analysis, risk control and residual risk evaluation.
• Documentation and records required for conformity assessment and regulatory submissions.

Typical use and users

Manufacturers of medical devices (including software as a medical device and embedded software), software development teams for regulated health products, regulatory and quality assurance professionals, notified bodies and conformity assessors, and auditors use IEC 62304 to design compliant processes and demonstrate that software‑related risks are identified, controlled and traced across the lifecycle.

Related standards

Commonly used alongside ISO 14971 (risk management for medical devices), ISO 13485 (quality management systems), IEC 60601 series (for electrical medical equipment where applicable), IEC 62366 (usability engineering), and health‑software specific guidance such as IEC 82304‑1 and relevant regional regulatory guidance (e.g., FDA software guidance and EU MDR-related guidance).

FAQ

Q: What is this standard?

A: IEC 62304 is the international standard that specifies life‑cycle requirements for medical device software; the 2015 publication is Amendment 1 to the 2006 edition, clarifying classification and legacy software requirements.

Q: What does it cover?

A: It covers software development processes (planning, requirements, design, implementation, verification/validation), maintenance, configuration management, problem resolution and the interface between software development and risk management. The amendment adds or clarifies requirements for legacy software and software safety classification.

Q: Who typically uses it?

A: Medical device manufacturers, regulated‑software developers, QA/regulatory teams, notified bodies and auditors use IEC 62304 to define and assess software life‑cycle processes.

Q: Is it current or superseded?

A: The 2006 edition with Amendment 1 (2015) remains the recognized edition; the base 2006 standard was reviewed/confirmed and the amendment is in effect — consult the IEC/your national standards body for the formal current consolidated text and any corrigenda or national adoptions.

Q: Is it part of a series?

A: IEC 62304 is part of the family of medical device standards and is routinely used with ISO 14971 (risk), ISO 13485 (QMS), IEC 60601 (electrical safety) and other medical‑software or usability standards such as IEC 82304‑1 and IEC 62366.

Q: What are the key keywords?

A: Medical device software, software life cycle, software safety classification, legacy software, verification, validation, risk management, maintenance.
