Abstract
This report describes the NPL-piloted intercomparison of compressive force measurements between: Commonwealth Scientific and Industrial Research Organisation (CSIRO), New South Wales, Australia; and National Physical Laboratory (NFL), Teddington, United Kingdom. Forces were measured in the range from 50 N to 5 kN during the period from 1 March 1999 to 14 June 1999. The results showed that the forces generated by each of the laboratories' deadweight force standard machines agreed between -0.005 % and +0.0093 % for increasing forces, and between -0.0358% and +0.010 % for decreasing forces. The agreement between the machines when the load cells calibrated range is restricted to between 40 % and 100 % of its maximum capacity is far greater; i.e. between -0.003 8 % and +0.0066% for increasing forces, and between -0.0098% and +0.0075% for decreasing forces. The agreements were all within the calculated uncertainties of measurement.
