In the United States, medical devices must meet Food and Drug Administration (FDA) standards. In Europe, the requirements include the Medical Devices Directive and IEC 60601-1-2, which are the recognized standards for testing electromagnetic compatibility of medical devices.
EMC testing of medical devices includes the following tests under IEC 60601-1-2:
- Electro-static Discharge
- Radiated Immunity
- Fast Transient
- Conducted Immunity
- Power Frequency Magnetic Fields (voltage dips, interruptions and variations)
It is important to note that in addition to EN 60601, there are dozens of additional standards that address unique features and characteristics of medical devices.
In assessing the EMC test requirements of a medical device, it is important to understand the definitions of medical device and accessory.
A medical device is any instrument, apparatus, appliance, material or other article, whether used alone or in combination, including the software necessary for its proper application intended by the manufacturer to be used for human beings for the purpose of:
- diagnosis, prevention, monitoring, treatment or alleviation of disease;
- diagnosis, monitoring, treatment, alleviation of or compensation for any injury or handicap;
- investigation, replacement or modification of the anatomy or of a physiological process;
- control of conception, and which does not achieve its principal intended action in or on the human body by pharmacological, immunological or metabolic means, but which may be assisted in its function by such means.
An accessory is defined as an article which while not being a device is intended specifically by its manufacturer to be used together with a device to enable it to be used in accordance with the use of the device intended by the manufacturer of the device.
