Suggested criteria of rating for occurrence of a failure in FME [11, 53].

Rating	Probability of occurrence	Possible failure rate
10	Extremely high: failure almost inevitable	≥1/2
9	Very high	1/3
8	Repeated failures	1/8
7	High	1/20
6	Moderately high	1/80
5	Moderate	1/400
4	Relatively low	1/2000
3	Low	1/15000
2	Remote	1/150000
1	Nearly impossible	≤1/1500000
