| error | |||
| Measured quantity value minus a reference quantity value. | |||
| Note 1: | The concept of ‘measurement error’ can be used both | ||
| a) when there is a single reference quantity value to refer to, which occurs if a calibration is made by means of a measurement standard with a measured quantity value having a negligible measurement uncertainty or if a conventional quantity value is given, in which case the measurement error is known, and | |||
| b) if a measurand is supposed to be represented by a unique true quantity value or a set of true quantity values of negligible range, in which case the measurement error is not known. | |||
| Note 2: | Measurement error should not be confused with production error or mistake. | ||
