UTM - Force load cells (DIN EN ISO 376)

Verification and calibration of force measurement systems (force gauge, load cell with amplifier and indicator) traceable to PTB/DKD/ILAC standards.

DIN EN ISO 376 describes calibration procedures and classification for force measuring systems used as transfer standards for inspection and calibration of single axis universal testing machines.

The calibration procedure measures the object in three diffent positions with increasing and decreasing measuring rows and force levels at 10 points.The result of the calibration is a classification according DIN EN ISO 376 with and without consideration of hysteresis and creep specification.

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 K-BNME (force reference standard measuring machine) with reference 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.

• Traceability for force gauges to monitor universal testing machines according to ISO 7500
• Calibration machines accredited according ISO 17025 in the scope from 2N to 250 kN
• Highest precision, low uncertainty (CMC better 0,02%)
