Well, the emissions test applies the limits of CISPR-11; A or B depending on what level of protection must be afforded radio users. You'll remember that there has been some controversy over approving use of electrosurgical equipment in residential environments. I'd think a good deal of the answer comes from one's customers. Would hospitals tolerate interference with RF patient monitoring? ER ambulance comms? How often, and how much? Running an electrocautery device might be tolerated for a few moments; a constant dead carrier on-channel >from a digital clock might be quite another matter. I think perhaps it is asking too much of a standard for devices to prescribe interference levels for facilities. But it would not surprise me if there were a European EMC standard for medical facilities. Cortland Richmond This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
