Verification and calibration of force measurement systems (force gauge, load cell with amplifier and indicator) traceable to PTB/DKD/ILAC standards.
The directive DKD-R 3-3 describes calibration procedures for force measuring systems. The reduced scope according procedure "C" calibrates the object in one position with one measuring rows with increasing and decreasing force levels at 5 points. This procedure can apply if "a-priori" knowledge for the accuracy and repeatability is available to calculate the uncertainty accordingly. The hysteresis is stated in the protocol.
The calibration for tensile and compression force (pull and push direction) is performed on an automated calibration stand with direct staggered mass application for forces up to 1000N. The lowest resolution is 0,2N for force gauges with 2N measuring range. Force gauges with nominal measuring range higher 1kN are calibrated on a stand with transfer standards up to 250 kN. Please consult the below table in order to check which measuring ranges of the calibration stands are covered by the accreditation in relation to the nominal force range of your gauge.
