xi: relative error of the transfer standard as obtained by laboratory i
xi = 100 [(Vt - Vs)/Vs], where Vt and Vs are the volumes indicated by the transfer standard (in m3) and measured by the national reference standard (in m3), respectively
Ui: expanded uncertainty (k = 2) of the measurement reported by laboratory i
The values of xi and Ui, expressed in %, are reported in Tables 4 and 5, respectively on pages 8 and 10 of the Final Report, for the complete range of flow rates and for all participants.
They are also presented under the form of one single table for all participants in Summary Results, and reproduced in the individual participant's page "Degrees of equivalence".
The standard uncertainty of the corrections and stability of the transfer standard is estimated to be equal to 0.031 % and is combined by root-sum-of-squares with the (Ui/2) values (see Section 5.6 of the Final Report). The resulting expanded uncertainty (k = 2), UiS, are given in the following tables.

TRANSFER STANDARD : A rotary gas meter (see Section 3 of the Final Report)
xi: relative error of the transfer standard as obtained by laboratory i
xi = 100 [(Vt - Vs)/Vs], where Vt and Vs are the volumes indicated by the transfer standard (in m3) and measured by the national reference standard (in m3), respectively
Ui: expanded uncertainty (k = 2) of the measurement reported by laboratory i
The values of xi and Ui, expressed in %, are reported in Tables 4 and 5, respectively on pages 8 and 10 of the Final Report, for the complete range of flow rates and for all participants.
They are also presented under the form of one single table for all participants in Summary Results, and reproduced in the individual participant's page "Degrees of equivalence".
The standard uncertainty of the corrections and stability of the transfer standard is estimated to be equal to 0.031 % and is combined by root-sum-of-squares with the (Ui/2) values (see Section 5.6 of the Final Report). The resulting expanded uncertainty (k = 2), UiS, are given in the following tables.
