EUROMET PROJECT
FINAL REPORT
1. Ref. No.: 377
2. Subject Field: Thermometry
3 Type of collaboration: Comparison
4A. Partners:
AIST-NMIJ, BNM-INM/CNAM, Cryogenic Laboratory, IMGC, INTiBS, MSL,
NIM, NIST, NMi-VSL, NPL , NRC, PTB, VNIIFTRI
4B. CEC funded?
No
5. Participating countries:
Japan CA China DE FR GB IT New Zealand NL PL RU US
6. Title:
Star Intercomparison of Low-Temperature Fixed Points Using Sealed
Triple-Point Cells
7. Progress:
All comparison measurements were completed, the results obtained for
the four investigated triple points have been evaluated, and the cells
are being sent back to the partners.
The main results are already published in two joint papers:

It is planned to prepare a second comprehensive paper for publication
in Metrologia (in 2006) and three detailed reports describing the
measurement method, the huge amount of data, and the obtained
information on the properties of the four fixed-point materials,
respectively, as follow-up activities. Thus, the project is completed.
