BIPM.RI(II)-K1.Sc-47 and EUROMET.RI(II)-K2.Sc-47
MEASURAND : Equivalent activity of 47Sc
There is no graph of equivalence since no degrees of equivalence with respect to the key comparison reference value could be computed.

BIPM.RI(II)-K1.Sc-47 and EUROMET.RI(II)-K2.Sc-47
MEASURAND : Equivalent activity of 47Sc
• Key comparison BIPM.RI(II)-K1.Sc-47
| Key comparison reference value: there is currently no key comparison reference value for this radionuclide. |
• Linking EUROMET.RI(II)-K2.Sc-47 to BIPM.RI(II)-K1.Sc-47
|
The value xi is the equivalent activity for laboratory i participant in EUROMET.RI(II)-K2.Sc-47 having been normalized to the value of the IRMM as the linking laboratory (see Final Report). |
| There are no degrees of equivalence with respect to the key comparison reference value. |
| The degree of equivalence between two laboratories i and j, one participant in BIPM.RI(II)-K1.Sc-47 and one in EUROMET.RI(II)-K2.Sc-47, or both participants in EUROMET.RI(II)-K2.Sc-47, is given by a pair of terms expressed in MBq: Dij = xi - xj and Uij, its expanded uncertainty (k = 2), approximated by Uij = 2(ui2 + uj2 - 2ful2)1/2 with l being the linking laboratory when each laboratory is from the EUROMET and f is the correlation coefficient. |
