Bilateral comparison of SPRT calibration at the ITS-90 fixed points of Ar, Hg, Ga, In, Zn and Al

Project Description

Bilateral comparison of calibration of SPRTs at the ITS-90 fixed points of Ar, Hg, Ga, In, Sn, Zn and Al. The goals of this comparison are:

• Demonstrate the technical competence of Roth + Co. AG in performing SPRT calibrations at the fixed points of Ar, Hg, Ga, In, Sn, Zn and Al.

• Link Roth + Co. Ag to the main KCs CCT-K3 and EUROMET.T-K3.Support the Roth + Co. AG submission and publication of CMCs in the BIPM KCDB.

Final Report 2014-05-31

The comparison has been completed and results are published in the KCDB.
