Under the Network Project a new one kg mass Comparator from M/s Sartorius AG Germany Model CC-1000S-L has been procured and installed during the year. The comparator has its maximum capacity 1 kg and repeatability of 2 μg. Using this new Mass Comparator, four 1 kg transfer standards have been calibrated against the national prototype kilogram with improved overall measurement uncertainty of 28 μg against existing CMC at 40 μg claimed in our CMCs of Appendix C of BIPM Database.

In continuation of organizing, coordinating and working as a Pilot Laboratory in APMP.M.M.K2 inter-comparison in mass measurements, after completion of the final circulation, the travelling standards have been recalibrated against the check standards and study of their stability for about three months have been carried out. After this study the measurement results were analyzed and Draft A Report of this inter-comparison was prepared and circulated among the participants for their comments, if any. In consultations with the participated laboratories Draft B Report is under preparation.

Under SAARC-PTB Technical Cooperation Programme, one week Training to the staff of National Bureau of Standards & Metrology (NBSM) of Nepal and to the staff of Measurement, Units, Standards & Services Department (MUSSD) of Sri Lanka was given on site.
