3 Terms and definitions
The following terms and definitions apply to this document:
3:1
Accuracy
The degree of agreement between the measured value of a measurand and its true value:
Note 1: The concept of "measurement accuracy" is not a quantity and does not give a numerical value: When a measurement provides a smaller measurement error, it is said that the measurement is more accurate:
Yes:
NOTE 2 The term “measurement accuracy” should not be confused with “measurement correctness” or “measurement precision”, although it is related to these two concepts:
Note 3 to entry: Measurement accuracy is sometimes understood as the degree of agreement between measured values assigned to the measurand:

3:2
Trueness
The degree of agreement between the average of an infinite number of repeated measurements and a reference value:
Note 1: Measurement accuracy is not a quantity and cannot be expressed numerically:
Note 2: Measurement accuracy is related to systematic measurement errors and has nothing to do with random measurement errors:
Note 3: The term "measurement trueness" cannot be expressed as "measurement accuracy" and vice versa:
