The IEC 60601-1 4th edition, in one place: the map, the timeline, and where to actually start

leoeisner — Tue, 28 Jul 2026 09:21:07 +0000

Almost nobody reads a thousand-page draft cover to cover. So here is one place to get oriented, then go deep only where it touches your device.

Edition 3.2 is around 500 pages. The 4th edition is heading past 1,000.

You have heard the headline: the IEC 60601-1 4th edition is coming, and it is big. Edition 3.2 is around 500 pages. The 4th edition is heading past 1,000, written across twelve hazard-based working groups.

The headline is not the useful part. The useful part is the question underneath it: where do you start, and what do you actually need to read? Almost nobody reads a thousand-page draft cover to cover, and nobody should have to. So this is a hub. It is one place to get oriented and then go deep only where it touches your device, as your device likely will not touch every corner of the standard.

Want this mapped to your specific device or learn more about IEC 60601-1, 4th Ed.? That is the work my team does with clients.

1. The structure: twelve hazard-based fragments

Edition 3.2 is organized by clause. You find a requirement by its number. The 4th edition is currently organized by hazard, split across fragment working groups that will later be merged into one document. Each hazard concept is a fragment, and each fragment has its own working group. Here is the whole map, and where each fragment stands today:

Fragment	Working Group	Hazard area	Latest draft
Frag 1	WG 37	General requirements	CD2 (Jul 2026)
Frag 2	WG 38	Physical environment hazards	CD2 (Jul 2026)
Frag 3	WG 39	User interface hazards: (usability, information supplied by the manufacturer, alarms)	CD2
Frag 4	WG 40	Materials hazards: (biocompatibility; cleaning, disinfection, & sterilization)	CD3 (Jul 2026)
Frag 5	WG 41	PEMS / software: (SaMD, SiMD, firmware, apps, OS, drivers)	CD1
Frag 6	WG 42	Electrical hazards	CD1
Frag 7	WG 43	Mechanical hazards: (including acoustic, pneumatic, vibration energy)	CD1
Frag 8	WG 44	Thermal and fire hazards	CD1
Frag 9	WG 45	Optical radiation hazards: (visible, UV, IR)	CD1
Frag 10	WG 46	Ionizing radiation hazards	CD2 (Jul 2026)
Frag 11	WG 47	Electromagnetic exposure (EMF) hazards, including SAR	CD2
Frag 12	WG 48	Electromagnetic disturbances: emissions, immunity, wireless coexistence	CD1

Draft status, committee-draft stage, as of 24 August 2026. “CD” = committee draft; higher numbers are later rounds. Treat all fragment content as current draft, not final.

That structure is not arbitrary, and you do not have to take my word for it. Behind it sits the Architectural Specification (approved 5 May 2020), which sets the direction for the edition, sharpening the focus of basic safety and essential performance and pushing toward discrete, design-ready requirements. The Design Specification Outline (30 November 2023) then implements that architecture, laying out how the work is grouped into the twelve hazard concepts above. An editing team, AG 50, the leadership of all twelve working groups, keeps twelve fragments reading as one standard.

Both specifications are public documents you can read yourself:

Architectural Specification (2020): assets.iec.ch/public/tc62/62_348e_Q
Design Specification Outline (2023): assets.iec.ch/public/sc62a/IEC_60601-1_Ed._4.0_Design_Specification

Most people never look at this layer. The original concepts have evolved since these specs were written, based on the experts and National Committee feedback, but they remain the best window into why the 4th edition is shaped the way it is.

2. Where the drafts stand, and the timeline

You do not have to track every document to stay oriented. Every one of the twelve fragments now has at least a first committee draft. Several are on their second draft, and Fragment 4 is furthest along at CD3. It will probably be the only CD3: for most fragments the intent is to publish a CD2, get comments from the National Committees, and move on. A third CD made sense only for WG 40, which has the time and bandwidth in its group to complete one before the project needs to move into the CDV1 phase.

Three recent fragment drafts dropped on 3 July 2026: Physical environment (Frag 2), Materials (Frag 4) and Ionizing radiation (Frag 10). All three are open for comment until 25 September 2026.

Most National Committees need your comments about two weeks before the IEC deadline so they can process them and submit to Geneva. Submit your comments with that buffer in mind, or check with your National Committee for its national deadline, so you do not miss the window.

And the map just moved again: Fragment 1 (General requirements) issued its next committee draft on 24 July 2026 (62A/1759), with comments open to 16 October 2026. Fragment 12 (electromagnetic disturbances) is the one still to come. WG 48 did not publish the Fragment 12 CD2 over the weekend of 1–2 August 2026, so it is not expected until after the Hamburg meeting in mid November 2026.

The 4th-edition timeline, from where we are now to publication around 2031.

Milestone	Target
Official kickoff	April 2024
Fragment committee drafts (CD1 / CD2 / CD3)	Through 2026 into early 2027
Fragments begin merging into one document (toward CDV1)	~ October 2027
Submit Merged CDV1	December 2028 (goal June 2028)
Merged CDV2 comments resolved	~ June 2030
FDIS Submitted	~ January 2031
IS Publication	~ April 2031

Treat the dates as goals; these schedules are likely to shift again. The point is the opposite of “relax, it is years away.” The text that becomes the 2031 standard is being written and commented on right now, and if you or your organization are not directly involved in writing the document (not one of the experts on the WG committees), the comment windows are the best way to provide your feedback.

3. Where to go deeper (the shelf)

You do not need to read everything, but you do need to start preparing now and understand the impact on your device designs, your test plans, your QMS, your document control, and your supply chain. Here is a starter kit to map to your device, plus a couple of orientation pieces:

The TÜV Rheinland 4th-edition seminar, presented by Leo Eisner, Caitlin Brady and Elizabeth Casey. Working-group material from the people writing the drafts.
The EU MDR / EN 60601-1 harmonisation cheat sheet on how the current standard lines up with the MDR, Annex ZZ, and state of the art.
The 4th-edition one-page cheat sheet: IEC 60601-1, 4th Edition: Strategic Changes and Preparation Strategy.
The LinkedIn series this hub grew from: the opening post lays out the three running series. The full, updated index of every post is below.

4. The series index: every post, by track

Three series run in parallel. This index is kept current as posts publish, so it is the one place to find them all. Each post is listed once, under the series it was written for; where it also touches another track, the description says so.

Start here

The opener: 500 pages to 1,000+, and the three running series — what the whole thing is and how it is organised.

Series 1: the CEP and CEF, start now

The conformity evaluation plan and the conformity evaluation file: what the 4th edition expects of them, and how to start putting them to work under Edition 3.2 now.

The CEP and the CEF: start now, under Edition 3.2 — what the plan and the file actually hold, the traceability chain, and why nothing in Edition 3.2 stops you working this way today.

Series 2: the 4th edition, fragment by fragment

How the edition is structured, and what is changing in each hazard working group.

Where the structure came from: the Architecture and Design Specifications, and AG 50 — also touches the CEP.
The twelve fragments, and where each draft stands today
Your EMC/EMD test plan is yours to write, not the test house’s — the plans you already owe today, and how Fragment 12 raises the bar in the 4th edition.
How much of the 4th edition actually applies to your device — almost every hazard fragment reaches almost every device, to differing degrees; only optical and ionizing radiation are genuinely device-specific.

Series 3: Standards Watch

New and draft standards as they land, inside the 60601 family and beyond it, with the comment windows that decide the final text.

The updated 4th-edition timeline and the July committee drafts — the schedule out to about 2031, and the three fragment drafts that opened for comment.
Combination products: ISO TS 24971-3, and where the risk lives — a device plus a drug or biological product, and the risks that only appear once they are combined.
EMF exposure assessment: IEC TS 63738 enters comment — the technical specification feeding the Fragment 11 electromagnetic exposure work.
IEC 60601-1 and IEC 62304 as Group Safety Publications — SC 62A’s application for horizontal status, and why it names two editions that do not exist yet. National Committee responses close 11 September 2026.

Start the readiness work early, so project time is not lost to avoidable redesign later.

5. Strategic readiness: your action items

You do not need the final text to start. Here is the readiness list I walk teams through:

Map your design controls against the draft working-group requirements now, rather than waiting for the next draft.
Run a full QMS gap analysis: risk management file, conformity evaluation file, and the EMF and biocompatibility assessment reports.
Pull R&D, RA/QA, software, labeling, supplier quality and manufacturing into your readiness reviews. This is not a regulatory-only exercise.
Embed cybersecurity, AI/ML and PEMS design inputs early in the pipeline, not at verification.
Update labeling, symbols, packaging and IFU against ISO 20417 and the working-group requirements.
Engage suppliers now for SBOM, spacing changes, power cords and component impacts. Supplier lead time is where these programs slip.

That list is the orientation. Turning it into a real gap analysis and a plan for your specific device is the part that takes experienced hands. Day to day, my team supports manufacturers, test labs, and regulators with exactly this: strategic readiness, CEP/CEF development, and training teams up on the 4th edition. It does not have to be a heavy engagement, either. One client took a four-hour CEP/CEF workshop and had the concept working in their process the next week.

Turn this into practical action

IEC 60601, 4th Edition: What’s Changing and How to Prepare

leoeisner — Sat, 28 Feb 2026 21:33:00 +0000

IEC 60601-1, 4th Edition

Strategic Shifts and How to Prepare

Companion post to my Easy Medical Device podcast episode on IEC 60601-1, 4th Ed., focused on what is shifting across the Working Groups and what RA/QA, Design, Test, and Management teams should do now.

Most organizations will feel the impact long before any formal transition date. The practical shift is that evidence expectations are tightening, scope is becoming clearer, and the standard’s direction is being shaped now through Working Group outputs. Teams that treat this as a design input and planning topic today will avoid late-cycle surprises in test strategy, labeling, and documentation tomorrow.

Translate 4th Edition Direction into Organizational Action

Quick to read and easy to share across RA/QA, Design, Documentation, Supply Chain, Test, and Management. Use it to brief teams and kick off impact planning for IEC 60601-1, 4th Edition.

This newsletter provides a high-level overview of 4th Edition preparation themes, including transition timing, regulatory positioning, and early planning actions. For deeper technical shifts that drive design inputs and evidence expectations, use the podcast and the one-pager as the primary briefing baseline.

Why this matters for MedTech

The architecture is structured around 12 hazard-based Working Groups, with a much expanded and clearer scope. There are stronger expectations for intended use, user environments, software and PEMS, wireless coexistence, and emerging EMF exposure concepts. These changes will flow into design inputs, QMS documentation, labeling and IFUs, verification and validation evidence, and test strategy.

Across the Working Groups, changes are focused on

Scope and Essential Performance
User environments and intended use
Software and PEMS
International wireless coexistence expectations
EMF exposure concepts
Hazard-based structure

How to use this kit

Brief leadership using the podcast as the shared baseline.
Revisit your intended use, user environments, and understand the changing scope of the standard now.
Assign owners to track the Working Groups most relevant to your product and markets.
Track areas likely to affect:
- QMS documentation
- Labeling and IFUs
- Test strategy and test planning
- Design impacts

Medical Device Compliance & Certification Summit – Why It Matters?

leoeisner — Tue, 23 Dec 2025 23:30:37 +0000

Medical Device Compliance & Certification Summit – Why It Matters?

Medical device and diagnostic compliance expectations are shifting earlier in the product lifecycle. IEC 60601 and related standards are no longer something teams can “handle at test.” Regulators increasingly expect standards interpretation, risk decisions, and test strategy to be visible and justified during design reviews and technical documentation development.

This shift is showing up in real ways – deeper design reviews, tougher pre-submission questions, and increased scrutiny of how standards were applied, not just whether a final test report exists.

To address this reality, Eisner Safety Consultants (ESC) is working with Nemko to deliver a three-day, in-person Medical Device Compliance & Certification Summit focused on how standards, testing, and regulator expectations intersect in real programs.

A focused, three-day program for engineering, regulatory, and compliance teams navigating IEC 60601, IEC 61010, EMC and RF requirements, certification strategy, and regulator guidance documents across FDA, EU, and other markets.

In-Person Training & Live Workshops

February 2–4, 2026
Carlsbad Inn Beach Resort, 3075 Carlsbad Blvd, Carlsbad, CA 92008

Designed for teams preparing new medical devices or diagnostics for market, working through recurring EMC or RF failures, or tightening FDA or EU MDR technical documentation ahead of submission or surveillance review.

Registration Summit Details

Who this summit is designed for

Electrical, EMC, RF, and systems engineers
Regulatory affairs and quality professionals
Product and compliance managers
Medical device and diagnostic startups preparing first submissions
Teams facing test failures, redesigns, or certification delays

What attendees will learn

How regulators evaluate standards application, not just test outcomes
Future impacts of IEC 60601-1, 4th edition concepts on design controls
Essential Performance and its role in risk management and review discussions
How EMC and RF strategies influence certification timelines
When IEC 61010 applies to diagnostic and laboratory equipment
Cybersecurity expectations under FDA and EU MDR
How guidance documents shape FDA and EU technical file expectations

How Eisner Safety Consultants Can Help

As regulatory expectations increase, delays are often caused by unclear standards interpretation, weak traceability between design decisions and requirements, and technical documentation that does not explain why choices were made.

Eisner Safety Consultants works with medical device, diagnostics, and combination device manufacturers every day to translate IEC 60601, IEC 61010, and related standards into practical design inputs, defensible test strategies, and documentation that aligns with FDA, EU, and other regulator guidance documents.

Podcast Feature

From engineer to “The IEC 60601 Guy” — my story and practical tips

I joined Duane Mancini on the Project Medtech Podcast to share how I became known for IEC 60601, why the series is a roadmap you can follow, and what 4th Edition changes mean for design, QMS, and documentation.

Episode 235

Listen on Web Open Spotify

A quick personal note

Nobody starts at the top as “The IEC 60601 Guy.” My path ran through early days at NASA, many years in test labs, and deep work in standards committees. What stuck with me is simple — stay curious, do the work, and show the work. That’s how we turn a dense standard into a practical plan.

Key takeaways from the episode

On the Project Medtech Podcast with Duane Mancini, M. Sc., I shared my genesis story of how I became known as The “IEC 60601 Guy”. Duane asked me to give listeners a 101 course on the IEC 60601 series, and I explained how I strive to “de-Greek” or demystify the standard series, and gave a preview of the big shifts coming in 4th Edition.

The “big picture” structure of the general standard, collateral standards, and particular standards

How lifecycle standards (risk management, usability, software) compare to type test standards in the 60601 family

Tangible changes to watch in the upcoming 4th Edition: clearer alarm requirements and impacts on design, QMS, & documentation

Why leaning on experts (internal or external) is key to getting this right for the impacts of 4th Edition

My goal is to “de-Greek” the process and show that IEC 60601 can be a roadmap , not a riddle

Whether you’re new to standards or a seasoned MedTech veteran, this episode shows how to approach IEC 60601 as a roadmap you can follow, instead of a riddle you can never quite solve.

What peers said

“If you want to know more about IEC 60601, Leo is the resource to go to … I recommend this episode to everybody working with medical electrical equipment.”

— Beat Keller

“Great to see how you became such an expert … I hope your story inspires young professionals to invest in becoming experts themselves.”

— Ronald Boumans

“It’s amazing that you covered the difference between process and test standards — there’s still a lot of confusion out there.”

— Tibor Zechmeister

IEC 60601-1, 4th Edition Survival Guide – Why It Matters For MedTech

leoeisner — Tue, 30 Sep 2025 09:23:00 +0000

IEC 60601-1, 4th Edition Survival Guide – Why It Matters For MedTech

The 4th Edition of IEC 60601-1 is no longer a future concern. Eleven of the twelve hazard fragments (WGs 37–48) have circulated Committee Drafts (CDs). All fragments have issued first CDs (WG 47 is at CD2), except WG 45 (Optical Radiation Hazards).

That means manufacturers, design houses, trade associations, test houses, and regulators must follow the working group outputs closely. If you cannot stay directly engaged in National or International (IEC) committees, you will need trusted expert guidance. These changes will impact design, QMS, labeling and IFUs, documentation, and test strategies.

🎩 Get your reviewer’s hat on – IEC 60601-1, 4th Edition Draft Fragments Have Dropped‼️ 🚀

leoeisner — Sat, 28 Jun 2025 01:09:39 +0000

Posted on LinkedIn June 19, 2025. Updated with extra blog content June 25, 2025.

Over the last two weeks – and with a Friday night (6/20/25 Geneva time – late) finale still to come – we’ve seen CD1s and CD2 (WG 47 ONLY) fly out for Fragments 5, 6, 7, 8, 10, 11, and 12 from WG 41 through WG 48, but for WG 45.

This is not just standards spring cleaning – these are foundational changes to the IEC 60601-1 General Standard, folding the Collateral standards into the core. If you have medical electrical equipment, medical electrical systems or software SaMD or SiMD you need to be aware of these changes. If you’re a manufacturer, test lab, trade association, Notified Body, Regulator or other interested party who owns a risk file… you need to review this.

These fragments cover hazards related to: • Electrical, mechanical, thermal, and fire • Software & PEMS (SaMD, SiMD, firmware, OS…) • EM Disturbance, wireless coexistence, ionizing radiation, and electromagnetic exposure (EMF)

The International comment deadlines start closing August 29th, with more due by September 12th. National deadlines close much sooner (does your summer holiday schedule conflict?)

Don’t wait for the FDIS – get involved now or get caught off guard later.

Read the full breakdown of all Working Groups, due dates, and what you should do now:

Here’s the who’s who of the Working Groups behind the fragments with CD1 to issue 20 July:

• WG 41 – PEMS (e.g., SaMD (Software as a medical device), SiMD (Software in a medical device), firmware, software, apps, OS, drivers) related hazards WG 41 link

• WG 42 – Electrical hazards WG 42 link

• WG 43 – Mechanical hazards WG 43 link

• WG 44 – Thermal and fire hazards WG 44 link

Other Fragments CD1s & CD2 have recently published – clock ticking to get your comments in:

• Fragment 11 – WG 47: Electromagnetic exposure hazards (not optical or ionizing but including SAR) WG 47 link CD2, closes 29 August

• Fragment 10 – WG 46: Ionizing radiation hazards WG 46 link CD1, closes 5 September

• Fragment 12 – WG 48: Electromagnetic disturbances (including wireless coexistence) WG 48 link CD1, closes 5 September

The early pack of CD1 Fragments released late last year

Fragments 1–4 and 11 from WG 37–40 & WG 47 were released as CD1 back on December 6, 2024, with comments closing February 28, 2025. You can still access them if you’re a National Committee member for SC62A or a WG participant. If not, consider joining — this is a major transformation, and early awareness = better preparation.

Join me for an Interactive Workshop Identifying Standards, Guidances, & Turn Standards into Your Competitive Advantage @ 10X

leoeisner — Mon, 31 Mar 2025 22:50:00 +0000

Join me, Leo Eisner, The IEC 60601 Guy, as I lead an interactive and fun workshop at the 10X Medical Device Conference in Newport Beach, Ca on May 7 – 8, 2025. Turn Medical Device Standards into Your Competitive Advantage, and discover practical strategies to leverage standards, avoid costly errors, and accelerate your product development cycle.

Don’t make the 5 costly mistakes companies make with Medical Device Standards. Learn from the IEC 60601 Guy himself.:

Late Identification of Applicable Standards: Leads to expensive redesigns and delayed timelines
Ignoring Expert Standards Guidance: Results in regulatory rejections and costly resubmissions
Unprepared Risk Management File for Testing: Risks unnecessary costs due to lack of strategic planning for compliance.
Unprepared Regulatory Submissions: Leads to costly setbacks and market-entry delays
Underestimating Education and Training: Creates knowledge gaps, increasing errors and compliance risks.

I want to thank Sean Smith and his team from 10X for all his help and dedication for putting on this event. He is doing an amazing job and please contact him if you are interested.

IEC 60601 Updates: What MedTech Need to Know for 2025 and Beyond Podcast

leoeisner — Thu, 12 Dec 2024 21:46:24 +0000

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:

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.
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.
New Requirements:
- Introduces new international requirements for wireless coexistence and other cutting-edge technologies (e.g., gas pathways, user interface aspects).
Consolidation of Standards:
- Collateral standards are being consolidated to improve consistency and reduce the update cycle time for the 60601 series.
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.
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.
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.
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.

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:

Fragment 1 (WG37) Status
Fragment 2 (WG38) Status
Fragment 3 (WG39) Status
Fragment 4 (WG40) Status
Fragment 11 (WG47) Status

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.
