    The paper presents the development of force calibration machines at Laboratory of metrology ZAG. Two new force calibration machines were developed, first one for 600 kN force range based on a ... material testing machine, upgraded with precision reference transducer and bridge amplifier, and the second one for 20 kN range based on deadweight direct loading principle. The procedure for evaluation of the machines is described and results of deviation between ZAG and PTB are presented. The uncertainty of force is 0,01 % in the 20 kN machine and 0,02 % in the 600 kN machine, sufficient for calibration of force transducer class 00 and 0,5 respectively, thus extending and improving force calibration capabilities in Slovenia.
