Calibration of gauge blocks by mechanical comparison: Northern European comparison final report

This comparison was undertaken to verify the competence of participating laboratories in mechanical gauge block calibrations up to 300 mm length. The initiative was taken by the Estonian national measurement institute Metrosert. The protocol used was adapted from EUROMET comparison 601 with small changes. The participants agreed that this would be carried out as a co-operational EUROMET project rather than as a supplementary comparison. Thus the general EUROMET guidelines for comparisons were essentially followed. The EUROMET project reference number is 639.
