Abstract
This report gives the results of a comparison of pressure
standards of seven European National Metrology institutes
in the range of negative gauge pressure from -950 hPa to
0 hPa.
This comparison was piloted by LNE and was carried out
from January 2011 to March 2012. This work is a part of
the EURAMET project 1170 and is registered as a
supplementary comparison EURAMET.M.P-S9. The transfer
standard used was a pressure monitor RPM4 A160Ks
manufactured by DH Instruments Inc., with a resolution of
0.1 Pa. The reference values have been determined from
the weighted mean of the deviations reported by the
participants for each specified pressure. Seventy-three
of the seventy-seven values (96%) reported by the
laboratories agree with the reference values within the
expanded uncertainties with a coverage factor k = 2.
