Annex F - Index
Provides the reader to the performance based approach for evaluating the reliability of SIF and to present system reliability methodologies that can be used to evaluate the system performance parameters, namely, the probability that the SIF fails to respond to a demand and the probability that the SIF creates a nuisance trip.
