significant fault (for CVDDs) #02085

Scope note 2

For CVDDs this concept applies to the whole device.

1. For the principal measurands this concept applies only to the electronic parts of the measuring system (in general the calculator) but not to the meter as such. Meters shall be tested and assessed according to the specific applicable OIML International Recommendation(s). 2. The significant fault for a calculator is calculated on the basis of the maximum permissible error applicable to the principal measurand and not on the basis of the maximum permissible error applicable to the calculator. 3. When a device is used for measuring two or more principal measurands (a calculator for example), it has a significant fault for each measurand.

Definition note 2

fault, the magnitude of which is greater than one fifth of the magnitude of the maximum permissible error for the calorific value. However a fault, the magnitude of which is smaller than 2 scale intervals of the CVDD is never considered as a significant fault

fault, the magnitude of which is greater than one tenth of the magnitude of the maximum permissible error for the relevant measurand However, whatever is the measured quantity: - faults greater than one tenth of the magnitude of the maximum permissible error corresponding to a quantity equal to one minute at Qmax are always considered as significant, - faults smaller than the relevant minimum specified quantity deviation are never considered as significant.
