| Zusammenfassung | This report presents results of a bilateral comparison between PTB and INTI in the range 1.5 kPa to 300 kPa of absolute gas pressure. The comparison was carried out in April–May 2008. The pilot laboratory was PTB. The pressure standards of the participants were pressure balances of the same type. The transfer standard was an electronic pressure gauge. Deviations of the transfer standard's pressures from the reference pressures generated by the laboratories' standards at specified pressures were reported by the participants and used for calculating degrees of equivalence between the laboratories. The results of the comparison presented in the Draft A report have induced INTI to revise their uncertainty by an increase in the uncertainty of the residual pressure. After this revision, the results presented in the actual report demonstrate equivalence within the expanded uncertainties (k = 2) reported by the laboratories at all pressures of the comparison. The degrees of equivalence stated in this comparison will provide a supporting basis for a new pressure CMC table of INTI. |
