API MPMS Chapter 4.8, Fixed Repeatability

API MPMS Chapter 4 Proving Systems Section 8 Operation of Proving systems Appendix A Estimating Random Uncertainty

This standard calculates the repeatability and average MF or MKF using the results obtained during proving for each trial run.

Availiable methods for calculating repeatability, R:


Symbol Description Units
R Repeatability -
MFmax Maximum meter factor from trials -
MFmin Minimum meter factor from trials -
MFavg Average meter factor from trials -
MFrun Meter factor for current trial -
