The relevant Recommendation may specify that durability errors are not significant, even when they exceed the value defined in 3.12, in the following cases: (a) The indication cannot be interpreted, memorized or transmitted as a measurement result; (b) The indication implies the impossibility to perform any measurement; (c) The indication is so obviously wrong that it is bound to be noticed by all those interested in the result of the measurement; or (d) A durability error cannot be detected and acted upon due to a breakdown of the appropriate durability protection facility.
