Calibration of gauge blocks by mechanical comparison

Project Description

It has been proposed and agreed to undertake a comparison of gauge blocks by mechanical comparison. The gauge blocks selected are of steel material and have nominal values as follows: 0.5 mm, 1 mm, 6 mm, 7 mm, 8 mm, 20 mm, 50 mm, 100 mm.

A single point or 5 point calibration will be undertaken on each gauge block by the measurement procedure being currently used at the project participant's laboratory, taking into account ISO 3650.

The deviation from the nominal length of each gauge block should be measured and the associated uncertainty of calibration evaluated.

The comparison will be based on the protocol used for Project 797.


Final Report 2016-10-31

The comparison has been completed and results are published in the KCDB.
