| calibration linearity | |||
| Closeness of agreement between indications obtained using calibrators in the first step of a calibration and indications predicted by the calibration function for the calibrators’ reference quantity values. | |||
| Note 1: | The concept applies to calibration functions of any mathematical form. The term ‘linearity’ is historical and refers to a time when calibration graphs were constructed on paper and were invariably considered to be linear. | ||
| Note 2: | Linearity of calibration may be expressed by measures of agreement (e.g., correlation coefficient) or deviation (e.g., standard error of calibration), obtained by regression of calibration data or assessed from a residual plot. See also: ref. 61. | ||
| Note 3: | Linearity of calibration is assessed during procedure validation. | ||
| Note 4: | Calibration linearity should not be confused with linearity of a measuring system. | ||
