Abstract

This report summarizes the Consultative Committee for Mass (CCM) key comparison CCM.P-K4.2012 for absolute pressure spanning the range of 1 Pa to 10 000 Pa. The comparison was completed via calibration of a transfer standard carried out at six NMIs during the period May 2012 and September 2013. Two nominally identical transfer standard packages were used in the comparison, Package B being circulated among participating laboratories and Package A remaining at the pilot lab in reserve as a back-up unit for the circulating package B. NIST’s experience in the previous low pressure comparison and detailed knowledge in the design and construction of high-stability resonance silicon gauge transfer standard packages [3,4] made it well suited to be the pilot. NIST completed construction and testing of a two new high stability transfer standard packages capable of absolute pressure measurements spanning the extended range of 1 Pa to 10 000 Pa which were used to accomplish the goals of the international key comparison set forth by the BIPM.
