Abstract

The 1.1 MN lever amplification dead weight force standard machine (FSM) and a new 3 MN hydraulic type build up FSM were installed at UME in 1995 and 2002 respectively. Both machines were regularly intercompared to each other and to PTB to maintain the performances. After making a new cooperation contract, a new intercomparison measurment were organised to see the existing performances of the both machines. The measurement results show that relative measurement uncertainty of the machines are better than 1·10^-4 for 1.1 MN machine and better than 4·10^-4 for 3 MN build-up machine of UME.
