Abstract :
In this paper we report the accuracy evaluation of the Italian primary frequency standard IEN-CsF1. We discuss the frequency shifts our frequency standard is corrected for and the procedure used for accuracy evaluation. In the last section we report a frequency comparison against two remote laboratory, the National Institute of Standard and Technology and the Physikalisch-Technische Bundesanstalt using the two way comparison technique.
