Fit failure in time definition

WebA. By definition Failure Rate is the total number of failures within an item population divided by the total number of life units expended by that population during a particular measurement interval under stated conditions. It is usually denoted by the symbol λ. The dimension of the failure rate is the reciprocal of time and the unit used is 109/hr = 1 FIT … Webfies the number of failures per unit hour. In practice, specifications in MTBF are more common, presumably because the failure rate is given in 1/hour, and is a smaller value (as is the „failure in time“ specifica-tion; 1 fit = 10-9 failures per hour), whereas the MTBF uses the unit of hours.
