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.

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.
