How does IEC 62366 relate to 14971, MDR and 60601-1-6?
IEC 62366-1:2015 + AMD1:2020 · References to ISO 14971 · Relation to 60601-1-6 & MDR
The short answer
Usability engineering does not stand alone. Use errors are a hazard source that feeds the ISO 14971 risk file — the two processes are interlocked (62366-1 references 14971 explicitly). For electrical devices, the 60601 collateral 60601-1-6 requires the application of 62366-1 — this is where the two standard families converge. Under the MDR, 62366-1 supports the ergonomics- and use-related General Safety and Performance Requirements; a presumption of conformity applies only where the standard is harmonised in the Official Journal of the EU.
62366 and ISO 14971 (risk management)
Use errors are hazard sources. The hazard-related use scenarios identified in the usability analysis are carried into the ISO 14971 risk file, evaluated there and given risk controls. 62366-1 §4 references 14971 explicitly — the two files must match each other.
62366 and IEC 60601-1-6 (the convergence point) — bridge to 60601
For medical electrical equipment, the 60601 collateral IEC 60601-1-6 addresses usability — but contains no process of its own; it requires the application of IEC 62366-1. So if you apply 60601 and have an operator interface, you inevitably arrive at 62366-1. This is the point where the two standard worlds meet.

62366 and the MDR (2017/745)
Usability and use-error analysis supports the General Safety and Performance Requirements of the MDR — notably the Annex I requirements on ergonomic design and risks arising from user characteristics. EN 62366-1 is among the standards relevant to the MDR; a presumption of conformity applies only once the reference is published in the Official Journal of the EU (OJEU).
62366 and ISO 13485 (QMS)
Usability engineering is integrated into design and development controls under ISO 13485 (Clause 7.3). The QMS ensures the usability file becomes part of the documented design and development evidence.
Frequently asked questions
Is 62366 alone enough for the MDR?
No. 62366-1 supports certain General Safety and Performance Requirements of the MDR and can — where harmonised and published in the OJEU — establish a presumption of conformity for the points it covers. Overall MDR compliance involves much more.
Does 62366 apply without 60601, i.e. to pure software?
Yes. 62366-1 applies in its own right to all device types. 60601-1-6 is only the path by which electrical devices are obligated to 62366-1 — software and IVD apply 62366-1 directly.
