a fault the magnitude of which is greater than 20 % of the maximum permissible error (mpe) for the measured quantity. The following are not considered to be significant faults: • faults arising from simultaneous and mutually independent causes in the measuring instrument itself or in its checking facility; • transitory faults being momentary variations in the indication, that cannot be interpreted, memorized, or transmitted as a measurement result; • faults implying the impossibility of performing any measurement.
