Annex A (informative) - Methodology for quantifying the
                        effect of hardware-related common
                        cause failures in Safety Instrumented
                        Functions
Annex B (informative) - Fault simulation test procedure
Annex C (informative) - SIL quantification of SIS - Advisory
                        software packages
Annex D (informative) - Failure mode effect, hazard and
                        criticality analysis
Annex E (informative) - Common cause failures and systematic
                        failure checklist
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.
