Abstract :
In May 1996 the international comparison of ac-dc voltage transfer standards at lowest level of uncertainty, using a multijunction thermal converter as the travelling standard, will be completed. Intermediate results show an agreement of the majority of the participating laboratories of better than 0, 4 ppm at the frequency of 1 kHz, 1 ppm at 20 kHz, 1, 8 ppm at 100 kHz and 16 ppm at 1 MHz.
