Abstract :
A Euromet international laboratory comparison (Project 393) has been carried out between 14 national standards laboratories. Thermistor mounts were used, equipped with PC7 as well as Type N connectors. The comparison is carried out using the normal equipment of the laboratory for high-quality external calibration. The results show good agreement in measuring the calibration coefficient of the thermistor mounts within the claimed expanded uncertainty (typically between 1% and 2%). It confirms the equivalence of national standards for RF power up to 18 GHz. In one case, corrective action is proposed
