Description: ratio of the number of failures of a given category to a given unit of measure; Name: failure ratio
Description: Number of failures within a population divided by the number of life units used by that population; Name: failure rate
Description: voltage which, together with the rated operating current, determines the use of the device and to which the various tests and the use categories refer. With single pole devices the rated rated operating voltage is generally the voltage over the pole. With multi-pole devices it is generally given as chained voltage; Name: Operating voltage
