Measurement of short gauge blocks by interferometry

Project Description

Comparison suggested and organised by CEM (ES), as continuation of comparison EURAMET.L-K1.2011, for CEM to recover its original smaller CMC, after having increased it temporarily as corrective action, due to some inconsistent results obtained in EURAMET.L-K1.2011 (EURAMET Project 1218). The comparison is just starting after agreement with participants, most of them also involved in the previous comparison.
