Spectral irradiance in the interval from 250 nm to 360 nm
n.b. All wavelengths within this interval are not covered by all listed comparisons (cf. Degrees of Equivalence)
|
This comparison was carried out independently at each wavelength. The key comparison reference value is calculated as the weighted geometric mean (with a cut-off) of the estimated systematic factors. It is stipulated to be unity by a special choice of the constraint equation. |
| The degree of equivalence of laboratory i with respect to the key comparison reference value is given by a pair of terms: Di, the difference between the estimated systematic factor for that participant and the key comparison reference value, being unity, and Ui, its expanded uncertainty at a 95 % level of confidence (see section 17.6.2 of the CCPR-K1.a Final Report). Di and Ui are expressed in relative units. |
| CCPR-K1.a.1 is a subsequent bilateral key comparison to CCPR-K1.a, between NMIA and SPRING Singapore. At any one common wavelength to both comparisons, the degree of equivalence of SPRING Singapore relative to the CCPR-K1.a reference value is computed using the NMIA results obtained in both comparisons, as explained in Section 9 of the CCPR-K1.a.1 Final Report (pages 20 to 24). This makes it possible to extend the CCPR-K1.a graphs of equivalence with one additional point from SPRING Singapore. |
| APMP.PR-K1.a.1 is a subsequent bilateral key comparison to CCPR-K1.a, between KRISS and VNIIOFI.
