Abstract: This guideline applies to static loading processes. In addition to the usual calibration sequences with three mounting positions, it does also describes simplified sequences which from a metrological point of view reduce the efforts to an acceptable minimum and thus help to reduce costs. For this purpose, certain prerequisites – such as the requirements of international rules for determining the measurement uncertainty – must be met. The user may go beyond the efforts described in this guideline but must not go below it. This guideline allows the realisation of practical calibration sequences and evaluations. In principle, simplified calibration sequences cannot lead to smaller measurement uncertainties than corresponding calibrations of the same calibration item according to more complex procedures (e.g. DIN EN ISO 376). When using reduced calibration sequences, it should be noted that in the case of high-quality force measuring devices it may not be possible to reach conformity with (manufacturer) specifications due to the increased measurement uncertainty. This guideline does no longer contain descriptions of classifications. This guideline applies to all force measuring devices determining force through elastic deformation of a body. It can also be used for force transducers alone. This guideline may only be used for force measuring devices that can be calibrated with increasing and decreasing loads, and with at least 3 force steps in each direction.
