Abstract

The paper gives a presentation of monitoring the results of measuring the gauge blocks length over a time period of fifteen years. The analysis has been performed on five gauge blocks of the highest accuracy class, of nominal lengths of up to 100 mm. Five different laboratories carried out the measurements, using three times interferometric and three times comparative methods. The measurement results analysis indicates constant need for checking the measuring procedure at the metrology laboratories.
