The two-week Mass Metrology Seminar is a "hands-on" seminar that incorporates approximately 30 percent lectures and 70 percent demonstrations and laboratory work in which the participant performs measurements by applying procedures and equations discussed in the classroom. The seminar focuses on the comprehension and application of the procedures, equations, and calculations involved. The seminar includes the operation of the laboratory equipment and a review of publications, standards, specifications, and tolerances relevant to the measurements. Training covers mass calibration procedures published in NISTIR 6969 and NISTIR 5672 and are suitable for the calibration of mass standards to OIML R111 Class E2 through M3 tolerances, ASTM classes 1 through 7 and NIST HB 105-1 Class F. Training is provided to enable the participant to correctly identify and implement the correct calibration process for each weight classification. Each procedure and the entire seminar incorporates concepts covered in the Fundamentals of Metrology seminar, especially, concepts related to metrological traceability, statistical analysis, measurement assurance methods, uncertainty analyses, software validation, and generation of ISO/IEC 17025 compliant calibration certificates for all measurements made during the seminar.
