INTER-LABORATORY COMPARISONS BETWEEN NMIJ AND ACCREDITED LABORATORIES FOR WATER FLOW IN JAPAN

N Furuichi, Kar-Hooi Cheong, Y Terao
  • Abstract:
    Inter-laboratory comparisons between NIMJ and four JCSS accredited laboratories in Japan for water flow are carried out for wide flowrate range from 0.005 m3/h to 5000 m3/h using five type transfer flowmeters. The deviations of test results between NMIJ and the accredited labs are within approximately 0.1% and the averages of these deviations for each accredited labs are within 0.025%. These result indicate a high capability of the calibration facilities in the accredited labs. To investgate the reason of the deviations in the comparisons, influences of temperature, density and measurement time are observed.
