What Is UL 60601-1? A Guide to Medical Computer Safety
UL 60601-1 is the North American safety standard for medical electrical equipment. A computer certified to it has been tested to operate safely in patient environments, with strict limits on leakage current, isolation, and electrical faults. Here is what that means when you specify a medical computer.
What the standard covers
UL 60601-1 (the US adoption of IEC 60601-1) governs electrical, mechanical, and thermal safety for equipment used in or near patient care. For a computer, the key areas are leakage-current limits, means of patient and operator protection, dielectric strength, and safe behaviour under a single fault.
Why medical computers need it
Commercial PCs are not tested for patient proximity. Near a patient, a device must not create a shock path even if one component fails. A UL 60601-1 medical computer uses a medical-grade power supply and isolation to meet those limits, which hospital biomedical departments often require before a device is allowed on the floor.
60601-1 vs 62368-1
IEC 62368-1 is the safety standard for general IT and industrial equipment. It suits office and factory use but does not cover patient contact. For bedside or medical-cart use, look for UL/IEC 60601-1; 62368-1 alone is not sufficient.
Frequently asked questions
What is UL 60601-1?
It is the North American safety standard for medical electrical equipment, covering leakage current, isolation, and fault safety for devices used near patients.
Is my computer 60601 certified?
Check the datasheet or nameplate for a UL 60601-1 or IEC 60601-1 listing. General 62368-1 certification does not qualify.
What is the difference between 60601-1 and 62368-1?
62368-1 covers general IT and industrial equipment; 60601-1 adds patient-safety requirements for medical use.
