NISTIR 6969 SOP 8 - Part 2

This 2 hour webinar will review and apply Uncertainty Calculations to the Modified Substitution Mass Calibration procedure from the "SOP 8, Part I" webinar.

Learning Objectives:

When this webinar is completed, participants will be able to:

  • IDENTIFY the components of uncertainty for the SOP 8 process and use them to develop an uncertainty budget
  • QUANTIFY the components of uncertainty for the SOP 8 process
  • CALCULATE the uncertainty of your SOP 8 process

Technology Requirement(s):

The Webcast will be streamed in medium bandwidth (350kbs), so viewers needed to have a constant connection during the webcast.
