Medical devices are increasingly software-driven, making security and regulatory compliance critical.
IEC 62304 is the international standard that defines the software lifecycle requirements for medical devices, ensuring safety, risk management, and regulatory approval.
For medical device manufacturers, compliance is not optional. It is required to bring products to market and maintain patient safety.
Why IEC 62304 Compliance Matters
Modern medical devices process sensitive patient data and perform critical functions.
Failure to comply can result in:
- Regulatory rejection (FDA, EU MDR)
- Patient safety risks
- Security vulnerabilities
- Product recalls and financial losses
IEC 62304 ensures that software is developed, tested, and maintained using a structured and risk-based approach.
What is IEC 62304?
IEC 62304 is an international standard that defines requirements for the software development lifecycle (SDLC) of medical device software.
It is recognized by major regulatory frameworks, including:
- FDA (Food and Drug Administration)
- EU MDR (European Medical Device Regulation)
- ISO 13485 (Quality management systems for medical devices)
The standard ensures software is:
- Safe
- Secure
- Traceable
- Well-documented
IEC 62304 vs IEC 62443 (Important Distinction)
IEC 62304 focuses on medical device software lifecycle and safety.
IEC 62443 focuses on industrial cybersecurity and system-level protection.
In practice:
- IEC 62304 ensures secure development of medical software
- IEC 62443 strengthens the security of connected environments and infrastructure
For connected medical devices (IoT/IIoT), both standards are often used together.
