A comparison of capacitance at 10 pF was conducted between thirteen participating laboratories from the Asia-Pacific region. Measurements were made between 2004 and 2006. The behaviour of the travelling artefact was consistent with a steady linear drift at a rate of approximately 0.1 µF/F per year. Despite the wide range of capabilities within the region, the results showed good agreement between all but one of the participating laboratories.Main text.

A comparison of capacitance at 100 pF was conducted between thirteen participating laboratories from the Asia-Pacific region. Measurements were made over the period 2004 to 2006. The behaviour of the travelling artefact was consistent with a steady linear drift at a rate of less than 0.1 µF/F per year. Despite the wide range of capabilities within the region, the results showed good agreement between all participating laboratories.Main text.

Currently, three single junction-type Thermal Voltage Converter (TVC) standard units represent the highest standard of AC (Alternating Current) voltages owned by the Electrical Metrology Laboratory, Research Centre for Metrology-Indonesian Institute of Sciences. The accuracy of the single junction-type TVC is maintained regularly via intercomparison processes using a one-step build-up and build-down method. To reduce the calibration process quantity, three steps of build-up and build-down measurements that refer to the 4 V measurement point of a HOLT production single junction-type TVC were carried out. The dissemination processes with the best measurement accuracy up to 20 ppm were successfully obtained from measurement points between 1 V and 20 V via 4-1V, 4-2V, 4-3V, 4-6V, 4-10V, and 4-20V formations.
