Abstract

The paper descriptes the inter-comparison of two force primary standards of 1 MN DWMs established by National Institute of Measurement and Testing Technology (NIMTT), Chengdu, China, and Istituto Nazionale di Ricerca Metrologica(INRIM), Torino, Italy. It was tested that the temperature coefficients of the two cells as transfer standard, and their long-term stability. There were results on the deviation of force generated by the two DWMs as well as their normalized error.
