Hybrid comparison of measurements from -196 °C to 0.01 °C

Project Description

There are no running comparisons in this temperature range and there is an urgent need for NSAI to obtain CMCs down to -196 °C.

Therefore, a hybrid comparison will be run between LMK (the issuing institute) and NSAI (the applicant NMI). The range of temperatures to be covered is from -196 °C to 0 °C in a comparison calibration, using an 25 Ohm SPRT, which has been blinded for the applicant NMI.

The protocol for the above comparison has been drafted and forwarded to the TC-T Chair.
