Definition: | 
limit, if it exists, of the quotient of the mean number of failures of a repairable item within time interval (t, t + Δt), by Δt, when Δt tends to zero
z(t)=limΔt→0+E[N(t+Δt)−N(t)]Δt
z(t)=limΔt→0+E[N(t+Δt)−N(t)]Δt
where N(t) is the number of failures in the time interval (0, t), where E denotes the expectation. |

Note: | 
Other terms used for failure intensity are “rate of occurrence of failures”, and “failure frequency”. |
