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.
