Description
Summary:After the development of the new 5 kN·m torque standard machine, LNE realized its metrological characterisation. This paper describes the determination of the uncertainties of this torque standard machine, including the uncertainty due to the mobility and the sensitivity of the arm lever. It describes also the comparison carried out with the national metrology laboratory of Germany PTB. The results show that the estimated uncertainties are satisfactory because divided by a factor of at least four compared to the old standard machines.
