| Comments | This comparison is initiated by NPL and is designed to compare the realization of the ITS-90 at the freezing point of zinc, 692.677 K (Zn FP) through a) the calibration of SPRTs and b) independent measurements of a transfer open zinc cell. Each participant will use two transfer standard SPRTs to measure two Zn fixed point cells, namely their own national standard cell and a transfer standard cell. The transfer standards used will provided by NPL, and will be two long-stem SPRTs and an open Zn fixed-point cell. |
