Effective efficiency measurements have been conducted at 10.0 GHz using a single load microcalorimetric technique on a thin film primary standard waveguide barretter mount designed and fabricated at National Physical Laboratory, New Delhi. The same mount was taken to three National Laboratories, namely NIST, USA; KRISS, Republic of Korea; PTB, Germany for an international comparison of effective efficiency measurements. This paper briefly describes the techniques employed for the measurement of effective efficiency of bolometer mounts by these countries. The results of effective efficiency are reported and intercompared.<>
