Description
Category, level "B, 1–4"
Diagnostic coverage
Failure in time: 1E-9/hour
Hardware fault tolerance: HFT = n means that n+1 faults could cause a loss of the
safety function
Mean time to failure - dangerous. Unit: Years
Probability of dangerous failures per hour. Consider this value if the safety device is
operated in high demand or continuous mode of operation, where the frequency of
demands for operation made on a safety-related system is greater than one per year.
Average probability of failure on demand, value used for low demand operation.
Discrete level used to specify the ability of safety-related parts of control systems to
perform a safety function under foreseeable conditions. Levels a–e.
Safety integrity level
Safe Torque Off
Safe Stop 1
Safety related electrical control system
