| Expression of the relation between indication and corresponding measured quantity value. | |||
| Note 1: | A calibration curve expresses a one-to-one relation that does not supply a measurement result as it bears no information about the measurement uncertainty. | ||
| Note 2: | A calibration curve is usually shown in the form of a smooth curve interpolating the data points. | ||
| Note 3: | The term “response curve” is sometimes used for a concept having the same or broader meaning. | ||
| Note 4: | In the VIM ‘calibration diagram’ (see ref. 1 entry 4.30) is defined as a “Graphical expression of the relation between indication and corresponding measurement result”. A calibration diagram allows instrumental measurement uncertainty to be represented in it and so differs from a calibration curve. In analytical chemistry the distinction between calibration curve and calibration diagram is rarely made. | ||
