IEC 61508: Effect of Test Policy on the Probability of Failure on Demand of Safety Instrumented Systems
Standard IEC 61508 provides probabilistic equations for determining the Average Probability of Failure on Demand (PFDavg) and the Average Probability of Failure per Hour (PFHavg) for some architectures of Safety Instrumented Systems (SIS) under the hypothesis of equal redundant components, taking in...
