INTERCOMPARISON OF FORCE TRANSDUCER CALIBRATION
It was the aim of this intercomparison of force transducer calibrations to check the agreement of the calibration certificates issued by the different metrology laboratories in the European Community. Each participant has been using his own methodology sometimes specified in national written standards. All methodologies were different. The intercomparison was done with two types of transducers: item - a stiff transducer of 500 kN; item - a rather flexible transducer of 100 kN.par The results have shown that the agreement between laboratories is better for a stiff transducer than for a flexible one, i.e. item - pm 1.5 10"-4" for stiff transducer item - pm 10"-3" for flexible transducer.par These values are for metrology laboratories which have a primary deadweight machine. Those laboratories which rely upon transfer transducers have higher uncertainties than can be expected. It was felt that a first step to improve agreement would be for all laboratories to improve the calibration methodology.
