CCT-K5, CCT-K5.1 and EUROMET.T-K5

MEASURAND : Temperature
NOMINAL TEMPERATURE : Tnom = 961 °C

  • Key comparison CCT-K5

The key comparison reference value TR for each nominal temperature Tnom and each lamp k is calculated on the basis of the median of measured radiance temperatures Ti(k, Tnom). Its standard uncertainty, u(TR), is obtained as the standard uncertainty of the median.

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

For each temperature Tnom the pair-wise degree of equivalence between laboratories i and j is given by a pair of terms: Dij and its expanded uncertainty Uij (k = 2) both expressed in K. The computation of Dij and Uij 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

The key comparison reference value TR for each nominal temperature Tnom and each lamp k is calculated on the basis of the median of measured radiance temperatures Ti(k, Tnom). Its standard uncertainty, u(TR), is obtained as the standard uncertainty of the median.

For each temperature Tnom the degree of equivalence of laboratory i with respect to the key comparison reference value is given by a pair of terms: Di and its expanded uncertainty Ui (k = 2) both expressed in K. The computation of Di and Ui is explained in the Addendum to the CCT-K5 Final Report. N.B. Pair-wise degrees of equivalence are no longer issued.

This bilateral comparison was carried out between VNIIM and NSC IM. The measurements were carried out from August to October 2014 using a vacuum tungsten ribbon lamb (S/N SI 10-300 No. 5). The individual results may be consulted in the COOMET.T-K5 Final Report .

  • Key comparison EUROMET.T-K5

This comparison involved eight participants and was carried out from October 1999 to February 2001.
The two transfer standards were Lamp S/N C564 and Lamp S/N C681 already used in CCT-K5.
The individual laboratory measurements and their uncertainties are given in Tables 5 to 11 of the EUROMET.T-K5 Final Report.

  • 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 Tnom. 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.
