Some weighing results requires high accuracy. Users frequently perform manual procedures to make these corrections. Two of these corrections are the hydrostatic buoyancy force and the balance calibration certificate corrections, the last one can be influenced by the tare weights use, and the tare function, in the weighing procedure. To provide an easy way to consider both simultaneously a spreadsheet was developed to identify and interpolate the right values obtained in the calibration certificate data and to use these data to correct the buoyancy force. In a first step, it will be distributed to the Inmetro´s laboratories.

This paper deals with the work done to define, construct and test a detailed critical part, spatially limited at about 10 cm3, reproducing the essential configuration of the FT-U magnet coil. The tests were performed at room and LN 2 temperatures in order to study the degradation of the insulating materials after repeated mechanical stresses. We describe criteria required to design a practical model with the possibility to simulate the thermo- -mechanical behaviour of the coil and allowing the measurement of the electrical insulation properties. The experimental set-up is described, as well as the operations for test analysis, optical observations and measurements on the components. Finally some results and typical microphotographs are reported.
