- Abstract:
- The national standard for length in Slovenia is materialised by gauge blocks 0,5 to 1000 mm. These gauge blocks are traceable to the primary standard and are used as a reference standard for calibrating standards from industry and calibration laboratories. The best measurement capability is not comparable with the capabilities of other European national laboratories having interferometric calibration systems but is covering the industrial needs at the moment. However, our aim is to improve measurement capability without involving interferometric system which would be too expensive for the industry. Research work in this field, which is focused in critical uncertainty contributions like calibration of the equipment, as well as environmental and human influences, is represented in the article. The calibration system will be improved by reconstruction of the device and surfaces for thermal stabilisation of gauge blocks and by automation of the measurement process. Numerous experiments for analysis of thermal and human influences have already been performed and the model for diminishing these influences was established.
