General standards information for researchers, lab staff and clinic staff. It is not medical advice and not a compliance determination for any specific device.
Short answer
EN IEC 60601-1-2 is the electromagnetic compatibility (EMC) collateral standard for medical electrical equipment: it sets requirements and tests for electromagnetic disturbances so that basic safety and essential performance are kept in the equipment’s intended environment. It is a safety standard, not proof that a device works as intended.
Definition and scope
The IEC publishes the current consolidated text as IEC 60601-1-2:2014+AMD1:2020 (edition 4.1, published 2020-09-01, 216 pages, stability date 2028). Its full title is “Medical electrical equipment – Part 1-2: General requirements for basic safety and essential performance – Collateral Standard: Electromagnetic disturbances – Requirements and tests” (IEC webstore).
The European adoption, as listed by the Estonian standards body EVS, is EN 60601-1-2:2015+A1:2021. The IEC text was approved in Europe without any modification, and the EN supersedes EN 60601-1-2:2007 (EVS). The search phrases “en iec 60601 1 2”, “iec 60601-1-2” and “en iec 60601-1-2” all point to this one standard family.
Its scope is the basic safety and essential performance of medical electrical (ME) equipment and ME systems with respect to electromagnetic disturbances. The equipment should work without interfering with other equipment in its intended electromagnetic environment. It also applies to ME equipment found to have no essential performance (EVS).

How it is used in practice
Intended-use environment sets the test levels
The fourth edition ties immunity test levels to the environment the equipment is intended for: professional healthcare facility, home healthcare, or special environments, aligned with IEC 60601-1-11 (IEC webstore). FDA’s webinar material on EMC states that the professional healthcare facility environment includes hospitals, physician offices and outpatient facilities, and also laboratories, while the home healthcare environment includes most environments not specified as special or professional (FDA CDRH webinar, 2023-02-02).
Other changes in the fourth edition
The IEC lists these changes: added tests and levels for portable RF communications used closer to the equipment; immunity tests and levels assigned per port; levels that reflect the highest reasonably foreseeable disturbance in each environment, so some are higher than before; removal of the term “life-supporting”; and new guidance on special-environment levels, risk management for electromagnetic disturbances, and pass/fail criteria (IEC webstore). For the wider risk-management context, see the CASRAI guide to ISO 14971 medical device risk management.
Essential performance
FDA’s webinar describes essential performance as most easily understood by asking whether its absence or degradation would result in unacceptable risk (FDA CDRH webinar, 2023-02-02).
Related standards
| Standard | Relationship to 60601-1-2, as stated in the sources |
|---|---|
| IEC 60601-1 | General standard for basic safety and essential performance; 60601-1-2 is its EMC collateral standard. See IEC 60601-1 explained. |
| IEC 60601-1-11 | Named by the IEC as the standard the environment categories are aligned with. |
| IEC 60601-4-2 | The standard FDA recommends for assessing whether a device performs as intended, because 60601-1-2 is limited to safety. |
| IEC 61326-1 and 61326-2-6 | EMC standards for in vitro diagnostic equipment. FDA lists the 2012 versions in its Non-Recognized Standards Database and partially recognizes the 2020 versions, stating their immunity requirements are not adequate. |
Laboratory instruments that are not medical electrical equipment are covered by different standards; see the CASRAI guide to IEC 61010-1 laboratory equipment safety.
Where it matters for labs, clinics and supply decisions
FDA’s 2022 guidance, “Electromagnetic Compatibility (EMC) of Medical Devices: Guidance for Industry and FDA Staff”, covers devices including in vitro diagnostics and aims to promote consistency and efficient review of EMC in device submissions (FDA). For in vitro diagnostics, FDA’s webinar says to use the test levels from IEC 60601-1-2 with device-specific acceptance criteria.
The information FDA asks manufacturers to describe doubles as a checklist a lab or clinic can look for in a manufacturer’s EMC documentation:
- Intended-use environment: professional healthcare facility, home healthcare or special environment.
- Power source: AC mains or battery, with both modes tested where applicable.
- Wireless technology: whether the device uses it.
- Essential performance: stated explicitly.
- Labeling: recommended separation distances, environments of use, compliance with the emissions and immunity standards, and any deviations.
Use this alongside the CASRAI guide to choosing diagnostic and patient monitoring equipment. Match the environment category on the documentation to where the equipment will actually be used.
Common misunderstandings
“Passing the EMC tests means the device performs correctly”
FDA’s webinar states: “IEC 60601-1-2 is a safety standard and has no performance or effectiveness requirements,” and recommends 60601-4-2 to assess whether a device performs as intended.
“EN and IEC are different requirements”
For this standard the European text is the IEC text approved without modification, so the difference is the designation and the date of the consolidated version, not the technical content (EVS).
“Every lab instrument is tested to 60601-1-2”
No. The standard applies to medical electrical equipment and systems. Laboratory and in vitro diagnostic equipment may be assessed under other standards, such as the IEC 61326 series, as described above.
FAQ
What is EN IEC 60601-1-2?
It is the EMC collateral standard of the IEC 60601 series for medical electrical equipment, published by the IEC as IEC 60601-1-2:2014+AMD1:2020 and adopted in Europe as EN 60601-1-2:2015+A1:2021.
Which edition is current?
The IEC webstore lists edition 4.1 (2014+AMD1:2020), published 2020-09-01, with a stability date of 2028.
Does it cover effectiveness?
No. According to FDA, it is limited to safety and does not test that a device is effective or performs as intended.
Is EN IEC 60601-1-2 the same as IEC 60601-1-2?
For the 2014 text, yes in content: the IEC text was approved in Europe as EN 60601-1-2:2015 without any modification. The designations and dates differ, not the technical requirements.
Which environments does it distinguish?
Professional healthcare facility, home healthcare and special environments.
