The facilities, instrumentation, and procedures currently used at the National Institute of Standards and Technology (NIST) for force measurement services are described. The uncertainty in the forces realized by the NIST primary force standard deadweight machines is reviewed. The maintenance and the uncertainty of the voltage ratio indicating system for strain gage load cells are discussed.
