Abstract

This paper describes an intercomparison at forces of 10 MN, 20 MN, and 30 MN between force standard machines located at FJIM, China, and NPL, UK. Two different types of transfer standard were used and the results demonstrated agreement between the two machines at each force of within 0,06 %, significantly lower than the relative expanded uncertainty claimed by either machine.
