What is IEC 60601, And Why is it So Critical for Medical Technology?

IEC 60601 is the most critical safety certification for medical electronic devices. Following its standards protects both patients and providers.

When it comes to electronics, medical devices have some of the highest standards possible for safety and reliability. Before they can be used on or near patients, every device must be exhaustively tested to ensure it won't break down or make a mistake.

Guiding these manufacturing and testing efforts is IEC 60601, the primary guideline for ensuring electronic medical devices are ready for the healthcare sector.

What is IEC 60601?
IEC 60601 is the international technical standard for electronic medical devices, as established by the International Electrotechnical Commission (IEC). The IEC was formed in 1906 to provide shared standards, guidelines, and language across national borders, and does so for nearly every industry that uses electronic devices, including the healthcare sector.

The IEC provides standards for far more than just medical devices, but IEC 60601 is undeniably the most important for electronic medical devices.

Origins
Originally published in 1977, IEC 60601 was written at a time when electronically powered medical devices such as ventilators, imaging devices, and anesthesia machines were becoming increasingly common in the healthcare sector. IEC 60601 was implemented to provide safety and reliability guidelines for these new devices and prevent accidents from happening.

Updates and Revisions
IEC 60601 has been significantly revised and updated over the years, with complete republishings in 1988 and 2005 to reflect changing priorities in device safety. There have also been numerous amendments meant to address ambiguities or questions that come up with new forms of technology. For example, the IEC published version 3.2 of IEC 60601-1, which updated risk management, usability, and software standards

What Does IEC 60601 Apply To?
Any and all electronic devices that are designed for the healthcare sector must adhere to IEC 60601. This includes any device meant to be used in a hospital or clinic, and applies regardless of whether the device is meant to be used by a healthcare provider or patient.

Requirements and Structure
IEC 60601 consists of almost one hundred general, collateral, and particular standards governing electronic medical devices. Covering every single one is obviously impossible for this article, but we will focus on two of the most important standards that every medical-grade device must meet: IEC 60601-1 and IEC 60601-1-2.

- IEC 60601-1: This basic standard covers the safety of medical devices and their ability to stop electrical discharges from passing into a provider or patient using the device. A medical computer that meets this standard can be considered safe, reliable, and will not accidentally shock its user or patient while in use.
- IEC 60601-1-2: This standard governs the safety and effectiveness of electromagnetic compatibility and shielding of medical devices, ensuring that devices will not interfere with each other and are protected from outside disturbances.

Testing and Certification
IEC 60601-1 and 60601-1-2 may be the standard for all devices, but further certifications will be required depending on the device's intended role. Manufacturers must determine what parts of IEC 60601 apply to them. For example, a device with radioactive emissions, such as an X-ray machine, must be tested under IEC 60601-1-3 standards.

Once their requirements are identified, manufacturers can begin integrating the necessary features into the product’s design. They must also conduct risk analysis and management plans, which identify potential dangers the device might face and how they will be managed. For example, a common risk for medical electronic devices is water damage. This risk can be managed by implementing a waterproof casing to protect the electrical components inside.

Testing is performed after initial prototyping is finished and all necessary measures have been integrated. While manufacturers can run pre-tests themselves, an official IEC 60601 test must be performed by an independent third party with ISO/IEC 17025 certification. This is to prevent falsified test results and ensure objectivity.

Benefits of IEC 60601
If it's so challenging and time-consuming, what are the benefits of following IEC 60601? A more accurate way to think about it would be to frame it as a necessity. A device that doesn't have IEC 60601 certifications should not even be considered for the healthcare sector.
Patient and Provider Safety
The first and most important factor that IEC 60601 ensures is the protection of healthcare providers and patients. Given that medical devices operate close to (or in some cases, inside) patients, it is extremely easy for any electrical discharge to jump from the device to the bodies of those nearby. An electrical short might also damage life-sustaining equipment such as a ventilator or pacemaker, putting that patient’s life in jeopardy. Designing and testing to IEC 60601-1 standards helps prevent this from happening.

Electromagnetic Harmony
Modern healthcare workflows rely on multiple devices working in concert with each other. A ventilator helps a patient breathe while a medical computer connected to monitoring equipment tracks the patient’s vital signs. If any one of these devices emits enough electromagnetic radiation to disrupt the others, it can have disastrous consequences. By meeting IEC 60601-1-2 standards, device manufacturers ensure that their products work harmoniously with other equipment.

Mark of Quality
For manufacturers, IEC compliance is an excellent way to showcase that their design and engineering teams are capable of delivering a quality product. An IEC 60601-compliant medical computer has been exhaustively tested and certified to work in real-world conditions just like those found in real hospitals and clinics. In turn, this gives end-users peace of mind, knowing that their equipment is proven and reliable.

IEC 60601-Certified Medical Computers from Cybernet
What is IEC 60601? It is the single most important certification that a medical tablet or computer can have. Without it, a device is not acceptable in healthcare. With it, you can rest assured that the device can protect you and your patients.
