Although instrumented indentation and atomic forcve microscope (AFM) are utilized extensively for the measurement of forces in the piconewton to millinewton regime, accurate calibration of these forces remains an obstacle to quantitative research. Deadweight mass calibration artifacts available from NIST allow for SI-traceable measurement of forces as small as five micronewtons with an uncertainty of parts in 104, but there is currently no method for calibration of forces smaller than this. Work a the Small Force Measurement Laboratory (SFML) at NIST is aimed at measuring and disseminating SI-treaceable force standards in the piconewton to micronewton regime. Efforts in the calibration of instrumented indenters and AFM cantilevers will be discussed, as will methods for disseminating these NIST-traceable small force standards.
