- Abstract:
- The speed measurement results of metrological verification of speedometers in the Portuguese Institute for Quality are presented. The associated measurement uncertainties are then taken into account. The measurement methodology and the results of nearly one hundred measuring instruments, with the uncertainty values are displayed and compared with the national maximum permissible errors. The results seem to suggest that the speed maximum permissible errors, for the metrological verifications, have to be changed.
