Final report on APMP.M.F-K4.b key comparison for 2 MN force

Abstract

This report gives the results of the APMP.M.F-K4.b key comparison in 2 MN force range. This regional key comparison was conducted under the Asia Pacific Metrology Program (APMP) to establish a link to the global CCM.F-K4.b key comparison.Seven institutes participated in this key comparison. The National Metrology Institute of Japan (NMIJ/AIST) served as the pilot institute. The Korea Research Institute of Standards and Science (KRISS) and the National Institute of Standards and Technology (NIST) together with NMIJ/AIST provided links to the CCM.F-K4.b key comparison. A pair of force transducers having 2 MN nominal capacities was circulated among the participants in a star formation.This regional key comparison revealed that all measurement results of the seven participants are coherent with the CCM.F-K4.b key comparison reference value within their uncertainties and that these participants are equivalent to each other.Main text.To reach the main text of this paper, click on Final Report.
