The Mass Metrology Seminar is a two-week, "hands-on" seminar. It incorporates approximately 30 percent lectures and 70 percent demonstrations and laboratory work in which the trainee performs measurements by applying procedures and nist-equations discussed in the classroom. The seminar focuses on the comprehension and application of the procedures, the nist-equations, and calculations involved. The seminar includes the operation of the laboratory equipment, review of publications, standards, specifications, and tolerances relevant to the measurements. Training covers mass calibration procedures published in NISTIR 6969 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.
Participants are encouraged to bring template versions of the mass calibration certificates issued by their laboratory as a starting point for the calibration certificates to be submitted during the seminar. Alternatively, participants should bring the calibration certificate they generated during the Fundamentals of Metrology seminar as a starting point. The former is recommended! Feedback and suggested changes to ensure ISO/IEC 17025 compliance will be provided during the seminar. Generation of calibration certificates will be required, so come prepared. A number of notebooks and course materials will be provided, so please ensure you have extra luggage space to carry these items.
Successful completion of the Fundamentals of Metrology Seminar is a prerequisite for the Mass Metrology Seminar. The Mass Metrology Seminar is built on the concepts learned during the Fundamentals of Metrology Seminar, applying units, measurement uncertainty, measurement assurance, traceability and Quality Management System concepts to the mass calibration procedures.
It is strongly recommended that you complete the Basic Mass Metrology CD as it will give you a head start on the Mass Seminar, including exposure to the contents of NISTIR 6969, Selected Laboratory and Measurement Practices , and Procedures to Support Basic Mass Calibrations and its associated errata pages. Completing the CD should take 16 to 40 hours. Participants are encouraged to read and comprehend as much as possible the content of NISTIR 6969 regardless of completing NISTSP 1001. If you have problems downloading the material, please send Yvonne Branden (link sends e-mail) a request to mail a copy of the CD.
Laboratory Auditing Program (LAP) problems are assigned at the completion of the course to those metrologists who participate in the NIST OWM State Laboratory Program. Acceptable completion of the problems is required for NIST Office of Weights and Measures Laboratory Recognition in support of mass calibrations. (See Handbook 143, Program Handbook training requirements)
One (1) year after class.
To receive a Training Certificate for this course, successful completion requires participants to actively participate in the entire course (e.g., take notes, engage in discussions, ask questions), complete all classroom, homework*, and application exercise assignments, and submit a series of calibration certificates as evidence of completion of all application exercises conducted during the hands-on portion of class exercises (guidance is provided in the course). A written final exam will contribute 50 percent of the grade and the class and laboratory exercises will be 50 percent of the grade. A passing grade (70 % minimum) on both portions is required to obtain a training certificate that indicates “successful completion”.
*Homework note: students generally report taking one to two hours for homework each night.
This training seminar is open to industry and government metrologists.
NIST OWM has a number of other training opportunities scheduled. For more information:
