Hybrid Comparison on Calibration of SPRT/HTSPRT in the specific sub-range of International Temperature Scale ITS-90 from 0.01 °C up to 660.323°C
Project Description
Hybrid and bilateral comparison on calibration of SPRT and HTSPRT at the ITS-90 fixed temperature points TPW, Sn, Zn and Al between DMDM (Serbia) and EIM (Greece).
The goals of hybrid comparison in this specific sub-rang of ITS-90 are to:
- demonstrate the technical competence of DMDM in performing SPRT/HTSPRT calibrations at the fixed temperature points of Al, as well as in the sub-range and
- support DMDM in submission of CMC services 1.3 Standard platinum resistance thermometers (SPRTs), subservices 1.3.2 Long-stem SPRTs including HTSPRTs for the Al point and also range.
Hybrid comparison will be done based on agreed protocol. MIRS/UL-FE/LMK will acting as third-party
