Abstract

The EUROMET comparison EUROMET. T-K3 is the regional extension of CCT K3. The comparison involved the 6 NMIs previously involved in CCT-K3 (LNE-INM/CNAM, SMU, INRiM, NMi-VSL, NPL, PTB) and 18 European national laboratories. The comparison was divided in five different loops, each coordinated by a co-pilot chosen from the laboratories having participated in the CCT-K3 comparison. LNE-INM/CNAM played the role of pilot in establishing the link between the five loops. In each loop, an artefact in the form of a standard platinum resistance thermometer (SPRT 25 ohm) was circulated among the participant laboratories. In order to have sufficient information about the possible drift of the SPRTs, the co-pilots have performed a calibration over the full temperature range at the beginning and at the end of the loop. An EUROMET Reference Value (ERV) taking into account the whole comparison was defined and the differences (TLab-TERV) were calculated with the associated uncertainties. A method for establishing the bilateral equivalence between the participants in CCT-K3 and in EUROMET T-K3 is proposed.
