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.

| Consultative Committee | CCRI (Consultative Committee for Ionizing Radiation) |
| Conducted by | EURAMET (European Association of National Metrology Institutes) |
| Comments | Results of this key comparison are older than 20 years and were thus deleted from the KCDB in June 2024 following the decision of the CCRI(II) at its 17th meeting in 2003 (see pages 37 and 38 of the CCRI Report of its 18th meeting in 2003) to gradually phase out old data to ensure that the KCDB maintains its currency. For the same reason, this comparison was placed in the KCDB archives on 25 June 2024. |

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. |
