Traceability of sealed fixed point cells (ITS-90)

Project Description

Since the last international comparison (CCT-K3) the tin and zinc fixed point cells of the BEV were damaged and subsequently repaired. To regain traceability, these national standards of Austria will be calibrated at the PTB using platinum resistance thermometers.

Final Report 2016-02-16

During the last international comparison (CCT-K3) the tin and zinc fixed point cells of the BEV were damaged and subsequently repaired. To regain traceability, these national standards of Austria have been calibrated in 2009 at the PTB using platinum resistance thermometers. Because there have been no futher calibration the last years the project will be closed.

Progress Report 2014-03-21

No new calibrations since 2009.

Progress Report 2009-03-19

Calibration of an Aluminium fixed point cell.
