Assessment of uncertainty in the calibration and use of flow measurement devices - Part 2 : Non-linear calibration relationships
Describes the procedures for fitting a quadratic, cubic or higher degree polynomial expression to a non-linear set of calibration data, using the least-squares criterion, and of assessing the uncertainty associated with the resulting calibration curve. The method of fitting a straight line to flow measurement calibration data is dealt with in ISO 7066-1.
