Abstract:
UME force standard machines, 11 kN and 110 kN dead-weight and 1.1 MN lever amplification, were installed into UME Force Laboratory in 1995. During commissioning of these machines in 1995 and 1997, two intecomparison measurements were realized between UME and PTB. Uncertainty level was 2 x 10-5 for dead-weight machines and is 1 x 10-4 for lever amplification machine. Marmara Earthquake influenced the force standard machines in August 1999. The epicentre of earthquake is 30 km to UME. Some connection points, welded parts and position of mass stacks were affected from this earthquake. After all repairment and adjustment was completed, a new intercomparison was realized with PTB in 2000. The measurements show that the uncertainty level is satisfactory and not changed due to earthquake.
