Verification and calibration of force measurement systems (force gauge, load cell with amplifier and indicator) traceable to PTB/DKD/ILAC standards.
The directive DAkkS-DKD-R 3-3 describes calibration procedures for force measuring systems. The full scope according procedure A covers the accuracy, repeatability and hystereses by calibrating the object in 3 differents positions, each with 5 increasing and decreasing force levels. This procedure is recommended if uncomplete specifications from the manufactureres data sheet, the type approval or previous calibration according DIN ISO 376 or DAkkS-DKD-R 3-3 are available only.
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.
