TRAVELLING STANDARDS : thermistor mounts of typeN 50 ohm connector
For each travelling standard, the key comparison reference value, x_{R}, is obtained as the unweighted average of the results of a number of selected laboratories (see section 7.2 on page 17 of the CCEM.RFK8.CL Final Report). The standard uncertainty, u_{R}, of the key comparison reference value is the standard deviation of the mean. x_{R} and u_{R} are dimensionless quantities. For TM1 at 10 MHz, x_{R} = 0.9681 and u_{R} = 0.0018 
For each travelling standard of typeN connector (TM1 and TM3), the degree of equivalence of laboratory i with respect to the reference value is given by a pair of terms, both dimensionless: D_{TMn i} = the difference between laboratory i result and x_{R}, and U_{TM}_{n} _{i}, its expanded uncertainty taking into account u_{R} (n = 1 or 3). These are combined to obtain the degree of equivalence of laboratory i for typeN connector, using the following expressions: D_{i} = avg(D_{TM1 i}, D_{TM3 i}) and U_{i} = [[avg(U_{TM1 i}, U_{TM3} _{i})]^{2} + [abs(D_{TM1 i } D_{TM3} _{i})/2]^{2}]^{1/2}. 
The degree of equivalence between two laboratories i and j is given by a pair of terms, both dimensionless: D_{ij} = (D_{i}  D_{j}) and U_{ij}, its expanded uncertainty (k = 2), U_{ij} = (U_{i}^{2} + U_{j}^{2})^{1/2}_{.}The pairwise degrees of equivalence are not explicitely calculated. 
The laboratories that are participants in both comparisons and which have an independent realisation of the quantity power (NPL, INRIM, NRC, and NMiVSL) are used for linking the results obtained in EUROMET.EM.RFK8.CL to the results obtained in CCEM.RFK8.CL. The linking process is explained in section 5 of the Linkage Report.
It follows that the table of degrees of equivalence and the graph of equivalence obtained for CCEM.RFK8.CL are extended with results obtained in EUROMET.EM.RFK8.CL.
The NMiVSL is the pilot laboratory of the bilateral comparison EUROMET.EM.RFK8.1.CL by which the results of MIKES participant in EUROMET.EM.RFK8.1.CL are linked to those obtained in EUROMET.EM.RFK8.CL (see EUROMET.EM.RFK8.1.CL Final Report).
