ceases, and from which the equipment under test recovers its normal performance, without operator
intervention;
Criteria C: Temporary loss of function or degradation of performance, the correction of which requires operator
intervention;
Criteria D: Loss of function or degradation of performance which is not recoverable, owning to damage to
hardware or software, or loss of data.
