In this work, the results of the measurement of the radiation conductance performed in the ultrasonic power measurement system of the Laboratory of Ultrasound (Labus) of Inmetro are presented. According to IEC 61161:2013, the Labus / Inmetro measurement system is considered a “primary measurement setup” since it took part in the BIPM Key Comparison CCAUV.U-K3.1, achieving satisfactory results. The measurements were carried out based on the primary measurement procedure for the determination of the radiation conductance, and the new results were compared with those previously obtained on the occasion of Key Comparison.
