Example 2.6 (Pump failure modes)
ОглавлениеReconsider the pump in Example 2.5 . The following failure modes may occur:
No output (the pump does not supply any water)
Too low output (i.e. the output is less than 60 l/min)
Too high output (i.e. the output is more than 65 l/min)
Pump does not start when required
Pump does not stop when required
Pump starts when not required…more failure modes depending on other functional requirements: for example, related to power consumption or noise.

Technical failures do not occur without a failure cause, defined as:
