This section provides training in the computation of measurement uncertainty estimates in accordance with the ISO GUM (Guide to the expression of Uncertainty in Measurement), as per requirements of the ISO/IEC17025 accreditation industry.

  • Approximate Course Time = 20 hours

    Online Instructor Supported Course:

    In this course, every student receives some private tutoring by the instructor as part of the online course.

    At the completion of the lesson material, the student is requested to attempt up to three (3) uncertainty analyses of their choosing and upload these to the instructor via the upload tool. The private tutoring session is then cooperatively scheduled between the student and the instructor. The submitted measurement uncertainty analyses are reviewed with the student, by the instructor. The analyses are discussed, corrected and/or completed by the student with the instructors guidance. Any questions that the student may have are answered. The online meeting uses QIMT's GoToMeeting® account, requiring only that the student has broadband internet access and a telephone or headset.

    On occasion, the online instructor may request a student having difficulty understanding the material schedule a free online tutoring session to clear up any confusion. It is no secret that the subject of measurement uncertainty analysis is a difficult subject for most technicians. We understand this and recognize the need to supplement this course with free tutoring sessions, as needed, to ensure each student can successfully perform measurement uncertainty analyses when they leave this training program.

    Course Objectives:

    After successful completion of this training course the student will be able to:

    • Understand the basics of statistics as it applies to the ISO GUM Method.
    • Understand the concepts of measurement uncertainty analysis.
    • Be able to perform measurement uncertainty analyses.

    This course will takes the student through the basics of the ISO GUM (Guide to the expression of Uncertainty in Measurement) to advanced concepts and methods designed to enable the student to perform measurement uncertainty analyses, from the simple to the complex, with confidence.

    Course contains numerous practical techniques for performing uncertainty analyses developed by Quametec for use in meeting the ISO17025:2005 requirements. Many of these techniques are currently in use in National Metrology Institutes and accredited laboratories around the world.

    Course includes printable lessons, sample uncertainty analysis procedure, example analyses created with Uncertainty Toolbox™ for exclusive student reference (requires Microsoft® Excel®), plus review of up to (3) three Student analyses! Course developer is the online instructor and will be available to answer questions from students via the forum, chat room, email, telephone or online meetings.

    It is recommended that the student purchase a license for "Uncertainty Toolbox™" (requires Microsoft® Excel®), if the student wishes to use the sample analyses for commercial work, which contain some of Uncertainty Toolbox™ copyrighted templates. To purchase "Uncertainty Toolbox™" call Quametec at 1-810-225-8588 M-F EST (9 am to 4 pm). To find out more

    Recommended Course Prerequisites:

    The student should be famialiar with traceability of measurements and the need for calibration. We recommend those very new to the subject, attend the QIMT live webinar "Introduction to Measurement Uncertainty and Risk Analysis".

    Those purchasing UncertaintyToolbox™ will want to attend the "UncertaintyToolbox™ New Users" webinar after completing the lessons and final test, but prior to the private analysis review session with the instructor. That way you can use the software for your submittals and get personal help with both the software and the ISO GUM Method of uncertainty analysis.
