Abstract

his report describes the results obtained from a supplementary comparison on the thermal expansion coefficient of gauge blocks in 2004–2006. The comparison was carried out by members in DG8 of CCL. The four gauge blocks, which were three ceramics blocks and one steel block, were calibrated by seven organizations in turn. Most reported results corresponded with each other within their expanded uncertainties (k = 2). However, some results for the steel gauge block had a systematic deviation from the key reference value. It was considered that the source of the deviation was mainly caused by the capability of the temperature determination of the gauge block.
