FORCE METROLOGY AT NIST

S.L. Yaniv, T.W. Bartel

Abstract

This paper describes the measurement services, the instrumentation and procedures available for force metrology at the National Institute of Standards and Technology, USA. The uncertainty in the forces realized over a range of 44 N to 53 MN is reviewed. The maintenance and the uncertainty of the voltage ratio indicating system for strain gage load cells are discussed.
