Comparison calibration of seven short steel gauge blocks (nominal lengths 1,005 mm to 90 mm) will be performed in four national laboratories. The organizing laboratory (LTM - FS Maribor on behalf of MIRS Slovenia) will prepare instructions and write final report. The planned duration time is 3 months.
The following features will be measured on each gauge block, according to ISO 3650:
- central length: deviation from the nominal value,
- where possible, variation in length: at 5 measuring points.
The results will be used for research purposes in the sense of reviewing uncertainty budgets and also to confirm the stated CMCs of the participating laboratories.
