• 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.
