Safe failure fraction (SFF)
Proportion of the overall rate of random hardware failures in a device that results in a safety-related failure or a detected hazardous failure, i.e. detected by a diagnostic test (based on report Ω 10 – INERIS).
Aussi bon que neuf; as good as new (AGAN)
Calculation assumption used in IEC 61508-6. After each periodic test, it is assumed that the value of returns to its initial value.
