| Definition: | the specified electromagnetic disturbance level used as a reference level for co-ordination in the setting of emission and immunity limits
NOTE 1 – By convention, the compatibility level is chosen so that there is only a small probability that it will be exceeded by the actual disturbance level. However electromagnetic compatibility is achieved only if emission and immunity levels are controlled such that, at each location, the disturbance level resulting from the cumulative emissions is lower than the immunity level for each device, equipment and system situated at this same location.
NOTE 2 – The compatibility level may be phenomenon, time or location dependent.
