IEEE C63.18-1997

This recommended practice is intended to serve as a guide for health-care organizations in evaluating the radiated radio-frequency (RF) electromagnetic immunity of their existing inventories of medical devices to their existing inventories of RF transmitters, as well as to RF transmitters that are commonly available. It can also be used for newly purchased medical devices and RF transmitters, as well as for prepurchase evaluation. This recommended practice applies to medical devices used in health-care facilities and to portable transmitters with a rated power output of 8 W or less. It does not apply to implantable medical devices, transport environments such as ambulances and helicopters, or to RF transmitters rated at more than 8 W. Testing with transmitters greater than 8 W should not be performed in health-care facilities because of possible adverse effects on critical-care medical devices that are in use in other areas of the facility.
