Key comparison CCT-K5

The key comparison reference value T_Rfor each nominal temperature T_nom and each lamp k is calculated on the basis of the median of measured radiance temperatures T_i(k, T_nom). Its standard uncertainty, u(T_R), is obtained as the standard uncertainty of the median.

For each temperature T_nom the degree of equivalence of laboratory iwith respect to the key comparison reference value is given by a pair of terms: D_iand its expanded uncertainty U_i (k = 2) both expressed in K. The computation of D_i and U_iis explained in the Addendum to the CCT-K5 Final Report.

For each temperature T_nom the pair-wise degree of equivalence between laboratories i and j is given by a pair of terms: D_ij and its expanded uncertainty U_ij (k = 2) both expressed in K. The computation of D_ij and U_ij is also explained in the Addendum to the CCT-K5 Final Report.

Linking CCT-K5.1 results to those of CCT-K5

The linkage is made through the common participation of PTB in both key comparisons, and is detailed in the CCT-K5 and CCT-K5.1 Linkage Report.

There are no APMP.T-K5 results to be linked to those of CCT-K5 for this nominal temperature.

Linking key comparison EUROMET.T-K5 to CCT-K5

The measurements of the EUROMET.T-K5 participants are directly linked to the key comparison reference value obtained in CCT-K5 as the protocols of the two key comparisons are identical and the transfer standards are the same (see in Chapter VII of the EUROMET.T-K5 Final Report).

Degrees of equivalence relative to the CCT-K5 key comparison reference values are computed for each of the transfer standards. Pair-wise degrees of equivalence inside EUROMET.T-K5 are available in the EUROMET.T-K5 Final Report (Tables 15 to 36).

Key comparison CCT-K5

Four Tungsten-strip lamps were used as transfer standards for radiance temperature measurements at specific currents corresponding to each nominal temperature T_nom. To shorten the measurement time significantly the set of transfer standards was split in two sets of two lamps for simultaneous comparisons in two loops. The pilot of each loop measured both lamp sets in order to establish a linkage mechanism described on page 19 of the CCT-K5 Final Report.
