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.
(ISO Guide 99:2007, Definition 2.16)
Theory and Application
Let’s start discussing the term “error” with the well-accepted definition of (ISO 99:2007), the International Vocabulary of Metrology (VIM), see “Definition.”
In Note 1, we recognize two...
