In the period December 2010-January 2011, INRIM participated to the CCM comparison CCM.M.P-K14 in gas media in order to assess the equivalence of the definition of the pressure in the range between 1•10-4 Pa and 1 Pa, by calibration of two spinning rotor gauges used as transfer standards. The measurements were carried out by the continuous expansion system (Dynamic system) in the range between 1•10-4 Pa and 9•10-2 Pa and by the static expansion system between 9•10-2 Pa and 1 Pa. This report details the followed procedure and the results of measurements made at INRIM. The results have shown the equivalence of static and continuous expansion systems at 9•10-2 Pa, the nominal pressure which can be generated by both the systems with sufficient accuracy.

Abstract
In the period December 2010-January 2011, INRIM participated to the CCM comparison CCM.M.P-K14 in gas media in order to assess the equivalence of the definition of the pressure in the range between 1•10-4 Pa and 1 Pa, by calibration of two spinning rotor gauges used as transfer standards. The measurements were carried out by the continuous expansion system (Dynamic system) in the range between 1•10-4 Pa and 9•10-2 Pa and by the static expansion system between 9•10-2 Pa and 1 Pa. This report details the followed procedure and the results of measurements made at INRIM. The results have shown the equivalence of static and continuous expansion systems at 9•10-2 Pa, the nominal pressure which can be generated by both the systems with sufficient accuracy.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
