NIST IR 6969

Selected Laboratory and Measurement Practices, and Procedures, to Support Basic Mass Calibrations

This NIST IR of Selected Publications has been compiled as an interim update for a number of Good Laboratory Practices, Good Measurement Practices, Standard Operating Procedures, Statistical Techniques and Reference Tables. This interim publication will be used as a reference document for the CD-ROM Mass Metrology Course being prepared by the NIST Weights and Measures Division. Many of these procedures are updates to procedures that were originally published in NBS Handbook 145, Handbook for the Quality Assurance of Metrological Measurements, in 1986, by Henry V. Oppermann and John K. Taylor.
