This 2 hour webinar will examine calibrating large tolerance weights using the Modified Substitution Mass Calibration procedure (SOP 8).
Learning Objectives:
At the end of (or during) this session, using your notes and SOP 8, participants will be able to:
- DESCRIBE the process of SOP 8;
- IDENTIFY sources of error;
- IDENTIFY when use of SOP 8 is appropriate; and
- Correctly IMPLEMENT SOP 8.

Participants need to locate a field weight kit made up of fourteen (14) 2-lb weights. This kit will be used to make measurements as part of the webinar. Measurement information will be used in Webinar NISTIR 6969 SOP 8 - Part 2.
Prerequisite(s):
Participants must have successfully completed the Fundamentals of Metrology Seminar.
Pre-Work:
- Read SOP 29: http://www.nist.gov/pml/wmd/labmetrology/sops.cfm
- Read SOP 8: http://www.nist.gov/pml/wmd/labmetrology/sops.cfm
- Select the proper balance to calibrate a 2 lb mass standard,
- Read all applicable instrument manuals for the balance and become familiar with the balance operation.
- Identify the 2 lb mass artifact that will be used as the standard during this calibration process and locate the applicable calibration report for that artifact.
- Review "Uncertainty Definition" slides from Fundamentals (attached)
- Complete an Uncertainty Budget table (attached) based on identified components currently being used in your laboratory. Think about whether there might be more components to consider.
Minimum Requirement(s):
Completion includes completing pre-work assignment, full attendance and participation in the session activities and discussion.
Audience:
Laboratory personnel who have responsibilities for developing, implementing, and/or improving the quality management system in their laboratory as well as those who are seeking OWM recognition and/or accreditation or improvements to support recognition/accreditation. This course is available for weights and measures participants only.
Cost:
Registration fees for State weights and measures regulatory officials and metrologists are funded by NIST OWM.
