How does IEC 60601 relate to MDR, 62304, 14971 and 62366?
IEC 60601-1 · Collateral 60601-1-6 (usability) · References to ISO 14971 & IEC 62304
The short answer
IEC 60601-1 does not stand alone. It requires an ISO 14971 risk management process (mandatory, not optional). If the device contains software, IEC 62304 governs its lifecycle. Usability is covered via collateral standard 60601-1-6 — which requires the application of IEC 62366-1. Under the MDR, EN 60601-1 supports the General Safety and Performance Requirements; a presumption of conformity applies only where the reference is published in the Official Journal of the EU.
60601 and ISO 14971 (risk management)
The 3rd edition of 60601-1 explicitly requires a risk management process and references ISO 14971. You cannot satisfy the risk- and performance-related clauses of 60601-1 without a current ISO 14971 risk management file. The two standards are interlocked, not parallel.
60601 and IEC 62304 (software)
If your ME equipment contains software or firmware, IEC 62304 governs its lifecycle while 60601-1 covers the electrical and hardware safety of the same device. They are complementary, not overlapping — both apply at once to a software-containing electrical device.
60601 and IEC 62366 (usability) — the bridge point
The usability of ME equipment is addressed via collateral standard IEC 60601-1-6. Crucially, 60601-1-6 contains no usability process of its own — it requires the application of IEC 62366-1. For electrical medical devices, the two standard families converge here: if you apply 60601 and have an operator interface, you must demonstrate usability engineering per 62366-1.

60601 and ISO 13485 (QMS)
ISO 13485 is the quality management umbrella under which 60601 testing, risk management and design controls are documented. 13485 does not say how safe the device is — it ensures the evidence is produced systematically and stays traceable.
60601 and the MDR (2017/745)
Applying 60601-1 supports the General Safety and Performance Requirements (GSPR, Annex I of the MDR). EN 60601-1 is among the standards harmonised under the MDR — but a presumption of conformity for the GSPRs it covers applies only once the reference is published in the Official Journal of the EU (OJEU). The harmonised list is updated in batches; check the current status for your edition.
Overview: 60601 and its neighbours
| Standard | Role for a 60601 device |
|---|---|
| ISO 14971 | Required risk management process — basis for "unacceptable risk" |
| IEC 62304 | Software lifecycle when the device contains software/firmware |
| IEC 62366-1 | Usability engineering — required via collateral 60601-1-6 |
| ISO 13485 | QMS umbrella for documenting all evidence |
| MDR (EN 60601-1) | Supports the GSPRs; presumption of conformity where harmonised in the OJEU |
Frequently asked questions
Do I need 62366 if I already apply 60601?
If your device has an operator interface: yes. 60601-1-6 references 62366-1 directly for the usability process — applying 60601-1-6 effectively means applying 62366-1.
Does 60601 make me MDR-compliant?
No. Applying 60601-1 supports certain General Safety and Performance Requirements of the MDR and can — where the standard is harmonised and published in the OJEU — establish a presumption of conformity for the points it covers. Your device's overall MDR compliance involves considerably more.
