5902 Measurement Assurance Basics

This session will cover the requirements in NIST Handbook 143 (essentially ISO/IEC 17025) on Measurement Assurance (Section 5.9).  We will specifically cover control charting techniques, reviews, assessments, and system-level assessments of measurement assurance systems.  Specific tools for administrative practices include a Measurement Assurance System Assessment that requires preliminary evaluation in your laboratory, and we will discuss one assessment that you conduct and submit prior to the seminar. (NOTE: This is not a 'how to create control charts' session.)

Learning Objectives

At the end of this webinar, using your notes and ISO/IEC 17025:2017 participants will be able to:

  • DESCRIBE their measurement assurance system during a Management Review;
  • REVIEW example control charts for problems, trends, and stability and be able to IDENTIFY assignable causes and possible action items; and
  • CONDUCT a system level assessment of their Measurement Assurance components.

Materials & Supplies



There are no prerequisites for this webinar. Knowledge of basic mathematics and statistics is expected.


  • Read SOP 9, Control Charts for Calibration of Mass Standards, and SOP 30, Process Measurement Assurance Program.  Available here:  Standard Operating Procedures
  • Review at least one control chart for your laboratory using the SOP 9 Appendix A Checklist for Creation or Evaluation of Control Charts.  Determine if action items are needed to make improvements.
    • Complete the Measurement Assurance System Assessment for ONE measurement parameter in your laboratory and submit to instructor for review prior to the session. We will share and review completed assessments during the webinar.

Pre-Work Deadline

Pre-work should be submitted to the instructor prior to the webinar by COB on Tuesday April 23, 2024.



Minimum Requirements

Successful Completion includes completing pre-work assignments, full attendance and acrive participation in the session activities and discussion, including the integrated quiz/calculations.


Laboratory metrology staff and administrators who are new to measurement assurance with control charts or who would like to review the SOP 30.  The session would also be useful for metrology staff who will be conducting on-the-job-training for new staff members.


The current registration fee for webinars is $289.  Registered participants will be sent payment instructions when their training request is confirmed.  Registration fees for State weights and measures metrologists are funded by NIST OWM.

  • Some features may not be enabled in all Adobe Connect meetings if one is using an Adobe Connect Server older than version 9.4.2 (required for Custom pods)
    • NOTE:  OWM discourages using the Adobe Connect app for iOS and Android because engaging with highly technical content and interactive polls are challenging on a small screen.

3. Media players

  • In order to access the event, you must have, at a minimum, Adobe® Flash® Player 13 or higher installed on your computer. Please visit to download the Flash Player.

4.  International Phone Calls

  • Before the webinar – Participants are responsible for verifying and testing that international calling is enabled on any telephone extension that will be used during the webinar. Some organizations permit only domestic calls, which may restrict the participant from making an international call to the OWM toll free number. A request to enable international call services may be necessary. Failing to test the international phone service could prevent participation in the webinar.
