In this episode of the Global Medical Device Podcast, Etienne Nichols sits down with Leo Eisner, founder of Eisner Safety Consultants and a leading voice in IEC 60601 standards development.

We unpack the upcoming revisions to IEC 60601, 4th ed., focusing on the rationale behind these changes, their impact on medical device design, and how MedTech professionals can prepare for the future.

Leo provides insights into the intricate process of updating global standards, shares practical advice for compliance, and discusses the role of risk management in ensuring safer, more effective medical devices.

Key Points:

  1. New Modular Approach:
    • The updated standard adopts a modular approach (12 working groups focused on specific hazard areas).
    • Simplifies updates by consolidating Collateral Standards into the General Standard.
    • Aligns better with global regulations.
  2. IEC 60601-1 4th Edition:
    • Focuses on addressing various hazards including:
      • physical environment,
      • electrical,
      • thermal and fire,
      • mechanical,
      • user interface (usability, alarms, information supplied by the manufacturer & user interface aspects),
      • materials,
      • optical radiation, and
      • electromagnetic exposure hazards.
  3. New Requirements:
    • Introduces new international requirements for wireless coexistence and other cutting-edge technologies (e.g., gas pathways, user interface aspects).
  4. Consolidation of Standards:
    • Collateral standards are being consolidated to improve consistency and reduce the update cycle time for the 60601 series.
  5. Timeline and Publication Dates:
    • Expected timeline for the fourth edition is 2029-2030.
    • Companies need to plan now, though the actual timeline may slip depending on various factors.
  6. Benefits of Proactive Planning:
    • Proactive planning and test preparation are essential for regulatory success.
    • Staying informed and embracing continuous learning in MedTech are key factors for success.
  7. Practical Advice for Compliance:
    • Begin designing for new standards early, even before they are finalized. MedTech design cycles are long.
    • Engage with industry groups and standards organizations.
    • Use test planning to streamline development and meet regulatory expectations efficiently.
  8. Engaging in the Standards Development Process:
    • Manufacturers are encouraged to engage in the standards development process and submit comments.
    • This proactive approach can help shape the standards and ensure they are practical and achievable.

These updates aim to enhance safety and performance while keeping pace with technological advancements. Manufacturers need to stay informed and prepare for the impact these changes will have on their product lines and quality systems.

Architectural Specification For Safety Standards of Medical Electrical Equipment, Medical Electrical Systems, and Software Used in Healthcare

Only 5 of the 12 Fragments went out for CD on 6 Dec 2024, which were Working Groups (WGs) WG37, 38, 39, 40 & 47 (Fragments 1, 2, 3, 4, & 11 respectively). The status of each of these Fragments is noted below:

The other 7 fragments will go out for CD approximately May ’25 (estimated schedule is my best intelligence). Fragments 5 – 10 & 12. You can look at the SC 62A Work Programme and find the Fragment number in the descriptions for each project on the first 12 projects of the Work Programme to find the status of each Fragment.

If you are a National Committee (NC) member and want to comment on the Fragment depending on your NC rules you may be placing your comments directly into the Online Standards Development (OSD) Platform for the Fragment. Other NCs are collecting the comments and then the NC Secretariat (or similar role) will be responsible for placing all the comments into OSD. Please check with your NC for your specific rules. Details about the OSD platform, How to use OSD, OSD resources (various training and other resources)

New terms and definitions which IEC 60601-1, 4th Ed. will be based on but other Technical Committees will adopt across the Healthcare sector to increase consistency – “International Electrotechnical Vocabulary (IEV) – Part 880: Electrical equipment, electrical systems and software used in healthcare” – IEC Website that has the schedule, list of draft documents. The CDV was released on 13 Dec 2024. If you are a National Committee Member of TC 1, TC 62, SC 62A, SC 62B, SC 62C, SC 62D, TC 65, TC 66, TC 76, TC 87, or SyC AAL you should be able to get access to this document and be able to comment on this document. This document is also being distributed for comment to ISO TC 210 and some additional ISO TCs .
