Full EN 60601-1 and EN 60601-1-2 testing for a simple Class IIa electromedical device typically runs EUR 25,000 to 70,000 at an accredited test lab, before any retests. Particular standards (the 60601-2-xx series), design rework after a failed test, and EMC chamber time are the three cost drivers that blow budgets. Plan for at least one retest cycle.

By Tibor Zechmeister and Felix Lenhard.

TL;DR

  • Full EN 60601-1 basic safety testing at a European accredited lab usually falls between EUR 18,000 and 45,000 for one configuration of a simple device.
  • EN 60601-1-2 EMC testing adds EUR 8,000 to 25,000 depending on chamber time, emissions class, and the number of operating modes you need to cover.
  • Particular standards (EN 60601-2-xx collaterals) can double the bill — a neonatal or ECG device carries obligations a general-purpose monitor does not.
  • Retest after a failed immunity or leakage test is the single most common budget killer; assume one retest round at roughly 30–50 percent of initial cost.
  • Startups save money by freezing the design before booking lab slots, running pre-compliance scans on a workbench, and choosing one labelled configuration rather than certifying every variant.
  • Cutting the wrong corner — using an uncertified power supply, skipping risk-based test justifications — costs more than testing properly the first time.

Why this matters

Founders budget for moulds, clinical work, and notified body fees, then discover that their benchtop prototype needs EN 60601-1:2006+A1+A12+A2+A13:2024 compliance testing before anyone can sign a CE certificate. The quote comes back. It is bigger than expected. The CFO goes pale.

Electrical safety testing is one of the few MDR line items where the invoice arrives in a single large chunk rather than spread across eighteen months of regulatory drag. That concentration makes it feel worse than it is. It also makes it one of the easier items to plan for, if you understand the cost categories and what actually drives them.

The goal of this post is to give you numbers you can put in a spreadsheet, and the reasoning behind them, so you can decide where to spend and where to save.

What MDR actually says

MDR Annex I §14 — "Construction and interaction with their environment" — sets the general safety requirements for devices including protection against electrical, mechanical and thermal hazards. §17 covers electronic programmable systems and software. MDR itself does not prescribe which test method proves conformity. It references harmonised standards as the presumption-of-conformity route.

For electromedical equipment the two workhorses are:

  • EN 60601-1:2006+A1+A12+A2+A13:2024 — general requirements for basic safety and essential performance of medical electrical equipment.
  • EN 60601-1-2:2015+A1:2021 — electromagnetic disturbances, the EMC collateral.

Conformity with these gives you presumption of conformity against the relevant parts of Annex I §14 and §14.5. If your device is in scope of a particular standard — for example the EN 60601-2-xx family covering infusion pumps, ECG monitors, surgical luminaires, patient warming systems — you must also demonstrate conformity there.

None of this is optional for electromedical equipment intended to be placed on the EU market. A notified body reviewing your technical documentation under MDR Annex IX will expect test reports from an accredited lab and justification for any deviations.

Cost categories — what you are actually paying for

Break the bill down into five buckets. This is how test labs quote, and it is how you should budget.

1. Basic safety to EN 60601-1 (clause-by-clause). This covers construction, markings, protection against electrical hazards, leakage currents, dielectric strength, mechanical hazards, excessive temperatures, hazard from unwanted radiation, and roughly 15 other chapter-level requirements. Expect EUR 18,000 to 45,000 for a straightforward device with one power supply, one applied part category, and no exotic enclosure. Larger systems with multiple mains connections, several accessories, or unusual environments push toward the top of that range.

2. Particular standards (the 60601-2-xx collaterals). If your device falls under a particular standard, the test burden grows. An ECG monitor needs EN 60601-2-27 testing on top of the general standard. A home-use oxygen concentrator sits inside EN 60601-1-11 for the home healthcare environment. Each particular standard adds EUR 5,000 to 25,000 depending on the complexity of the added clauses. This is the category most startups underestimate because the first quote often only prices the general standard.

3. EMC to EN 60601-1-2. Conducted and radiated emissions, radiated and conducted immunity, electrostatic discharge, electrical fast transients, surges, magnetic field immunity, voltage dips and interruptions. Chamber time is the dominant cost here. Budget EUR 8,000 to 25,000 for a device with a handful of operating modes. The number of modes matters: every mode you declare essential performance in must be monitored during every immunity test. Three modes does not cost three times one mode, but it is not free either.

4. Risk management and documentation prep. Labs do not test a device in a vacuum. They need your risk management file per EN ISO 14971:2019+A11:2021, your essential performance definition, your test plan, and usually a pre-test meeting. A serious lab will charge EUR 1,500 to 5,000 for review and setup. Cheap labs skip this. That is how devices fail on day one because nobody agreed what "normal condition" and "single fault condition" mean for your topology.

5. Retest after failure. Honest budgeting assumes at least one retest cycle. Typical retest costs are 30 to 50 percent of the original category, because the lab only repeats the failed clauses. If you fail leakage current in single fault, you repeat leakage. If you fail radiated immunity at 80 MHz, you rebook a chamber slot. The total retest envelope for a first-time startup lands around EUR 8,000 to 20,000 on top of everything above.

Add those up for a simple Class IIa device with one particular standard and realistic retest reserves: roughly EUR 45,000 on the low end, EUR 110,000 on the high end. For a Class I device with no particular standard and a generous design margin, EUR 25,000 to 60,000 is plausible.

A worked example

A three-founder startup in Graz is building a desktop phototherapy device for treating neonatal jaundice at home. Single-phase mains power, one applied part (the light panel), one operating mode, no wireless. Classified IIa. They come to us with a prototype and a deadline.

Scope:

  • EN 60601-1:2006+A1+A12+A2+A13:2024 — general safety. Quote: EUR 28,000.
  • EN 60601-2-50 — particular standard for infant phototherapy equipment. Quote: EUR 14,000.
  • EN 60601-1-11 — home healthcare environment. Quote: EUR 6,000.
  • EN 60601-1-2:2015+A1:2021 — EMC. Quote: EUR 11,000.
  • Test plan review, pre-test alignment, risk file check. Quote: EUR 3,000.

Subtotal: EUR 62,000. We push them to budget a further EUR 20,000 for retest reserve and design rework. Total electrical safety envelope: EUR 82,000.

They were initially quoted EUR 30,000 by a generalist lab that did not mention the two collaterals. That is how startups end up EUR 50,000 short halfway through the project.

The Subtract to Ship playbook

Apply Subtract to Ship to the testing budget itself. Remove everything that does not earn its place.

Freeze the design before you book the lab. The single most expensive mistake is booking a test slot with a prototype you are still modifying. Every design change after the test report closes triggers a delta evaluation — sometimes free, often not. A six-week design freeze before lab entry typically saves one full retest cycle.

Pre-compliance at the bench. Cheap scanning tools and a rented near-field probe set cost a few hundred euros a week. A half-day pre-scan catches the worst emissions problems before you spend EUR 4,000 on chamber time. Not a substitute for accredited testing, but a brutal reality check.

Certify one labelled configuration, not every variant. MDR allows families of devices. If your roadmap includes three enclosure colours and two accessory cables, pick one lead configuration for the first test campaign. Expand by variant testing later, when revenue exists.

Use a pre-compliant power supply. A medical-grade power supply with its own IEC 60601-1 report halves the work your device has to do on isolation, leakage, and dielectric strength. Yes, it costs more than a commodity brick. It costs less than failing leakage testing twice.

Write the essential performance statement before you talk to the lab. This is the single document that determines how many operating modes you pay to monitor during immunity testing. A sharp, narrow essential performance definition is free. A vague one doubles your EMC bill.

Do not shop on price alone. The cheapest accredited lab quote is almost always incomplete. Ask every lab the same three questions: which clauses are in scope, which particular standards apply, and what a retest would cost. Apples to apples, prices compress.

Reality Check

Use these questions before you sign a lab contract.

  1. Have you identified every particular standard (EN 60601-2-xx and EN 60601-1-xx collaterals) that applies to your device, and are they all in the quote?
  2. Is your essential performance statement written, reviewed, and narrow enough to defend during EMC immunity testing?
  3. Is the design genuinely frozen — mechanical, electrical, firmware — for the duration of the test campaign?
  4. Do you have a retest reserve of at least 30 percent of the initial quote in the budget?
  5. Have you pre-scanned for emissions on a bench before booking chamber time?
  6. Is your risk management file per EN ISO 14971:2019+A11:2021 current and consistent with the test plan?
  7. Have you chosen one labelled configuration as the test article rather than trying to cover every variant?
  8. Does your power supply carry its own 60601-1 compliance evidence, reducing what your device has to prove?

If you answered no to three or more, stop and fix those before you commit to a test slot.

Frequently Asked Questions

Can we do any of this ourselves to save money? You can do pre-compliance scanning, bench-level safety checks, and documentation prep yourself. The final compliance testing must be done by an accredited lab if you want the report to carry weight with a notified body. DIY pre-compliance saves money; DIY compliance does not exist.

Is EMC testing really separate from basic safety testing? Functionally yes. EN 60601-1 and EN 60601-1-2 are different standards, usually tested in different rooms by different engineers. Some labs bundle the quote but the work is separate. Budget and schedule them as two activities.

What if we change the enclosure after testing? Minor cosmetic changes are usually fine. Changes affecting clearances, creepage, thermal behaviour, or EMC shielding trigger partial retesting. The test lab decides, not you. Get the decision in writing before you spend engineering time on the change.

Do we need particular standards if our notified body did not mention them? Yes, if they apply to your device. Presumption of conformity under MDR Annex I depends on the state of the art, and particular standards are the state of the art for their device category. A notified body that did not flag them will flag them at the next audit.

How long does the whole test campaign take in calendar time? Booking lead times at accredited European labs are currently four to twelve weeks. The testing itself takes two to six weeks. Retest cycles add another two to six weeks each. Plan four to six months from "design frozen" to "signed test report."

Can we use a report from a non-European lab? A report from an IECEE CB Scheme laboratory can be converted for EU use, which saves time if you are also certifying elsewhere. A report from a random non-accredited lab is worth nothing to a notified body.
