fault exceeding the applicable fault limit value


Note For particular types of measuring instruments some faults exceeding the fault limit may not be considered a significant fault; the applicable Recommendation shall state when such exception applies. For example, the occurrence of one or some of the following faults may be acceptable:

• faults arising from simultaneous and mutually independent causes originating in a measuring instrument or in its checking facilities;

• faults implying the impossibility to perform any measurement;

• transitory faults being momentary variations in the indication, which cannot be interpreted, memorized or transmitted as a measurement result;

• faults giving rise to variations in the measurement result that are serious enough to be noticed by all those interested in the measurement result; the applicable Recommendation may specify the nature of these variations.
