There is no MTBF or MTTF value for electromechanical relay.
The lifespan of relay depends on the operating cycles.
The mechanical durability value corresponds to B10 value. For RXM relay, the B10 value is 10 million operating cycles. B10d will be 20 million operating cycles (B10d = 2*B10)
B10d = Dangerous portion of the B10
(The electrical durability is given following the breaking capacity and the utilization category.)
RXM4: B10 = 10 000 000, portion of dangerous failure = 50%, B10d = 20 000 000
RXM3: B10 = 10 000 000, portion of dangerous failure = 50%, B10d = 20 000 000
RXM2: B10 = 10 000 000, portion of dangerous failure = 50%, B10d = 20 000 000
