The Impact of IEC 60601-1, 4th Ed on RA/QA, Design, Doc Control, Test, Supply Chain, & Management
The upcoming 4th Edition of IEC 60601-1 represents a major shift in how medical electrical equipment safety is structured and applied. Building on Edition 3.2, the 4th Edition introduces a new structuring of the series, coordinated across 12 hazard-based working groups. These changes will directly influence risk management, design & document controls, testing strategies, and QMS impacts.
In this session, Leo Eisner (“The IEC 60601 Guy”) will provide a practical walkthrough of the 4th Edition, highlighting:
​
-
Scope change – inclusion of software and clearer definitions of user groups and use environments.
-
IEC 60601 Series structuring – The collateral standards will be folded into the general standard and will discuss the impact.
-
Regulatory involvement – the elevated role of regulator involvement, and what that means for compliance pathways.
-
Design controls & QMS integration – impacts across requirements definition, verification/validation, labeling, EMC/performance, and change control.
-
Technical Shifts – Changes to hardware and documentation requirements will have a significant impact. Such as Ingress protection increases, battery technology changes, ISO 20417, User Interface Aspects, Wireless Coexistence, RF Fields, and other new requirements
-
Next steps – early actions teams can take now: gap assessments, hazard-requirement mapping, risk-based testing plans, and targeted document control updates.
Participants will leave with a clear view of how the 4th Edition reshapes the compliance landscape from hazard identification to lifecycle controls – and actionable guidance to prepare their organizations effectively.
