Bilateral comparison in high gauge pressure 250 MPa

Main text CMI and GUM agreed a bilateral comparison in high gauge pressure up to 250 MPa in oil medium. This comparison was initiated as EURAMET Project No. 1375 and obtained a designation EURAMET.M.P-S16. A direct comparison method was used - a pressure balance of GUM reference standard was compared to a pressure balance of CMI. There were no discrepant measurements (with the resultant standardised equivalence degrees between 0.15 and 0.88) and CMI and GUM confirmed their equivalence.
