UNCERTAINTY SCOPE OF THE FORCE CALIBRATION MACHINES

摘要

Using the method specified in EAL-G22 (new ref. EA-10/04) with corresponding mathematical model functions for each type of force calibration machine and providing a practical example, the paper describes the approach adopted to apply EAL-R2 (new ref. EA-4/02) to the statement of the best measurement capability achievable for forces. The scope of the calibration laboratory can thus be defined according to the criteria of the accreditation body ensuring that the normalized error remains < 1, when inter-laboratory comparisons are performed.
