MEASUREMENT UNCERTAINTY ANALYSIS
(An introductory level course on Measurement Uncertainty is
also available via on-line learning. See
www.qcinspect.com/online).
Learn how to compute measurement uncertainties for ISO/IEC 17025:1999 laboratory accreditation
in a correct and practical way. To ensure international acceptance, the course is based on the
full GUM Method rather than any simplified questionable methods or techniques.
One of the major challenges to ISO/IEC 17025 compliance is meeting the measurement uncertainty
analysis requirements. It's been said, "Those that can…do!" Since 1998, our
instructor, has performed over 1,000 measurement uncertainty analyses for companies
worldwide and has provided training to over 300 companies internationally.
To ensure
international acceptance, the course is based on the full "ISO GUM Method" rather than
any watered down or simplified questionable methods or techniques. The instructor, James D.
Jenkins, is a Laboratory Accreditation Assessor, Technical Advisor and Measurement Uncertainty
Analysis Instructor for a U.S.-based Accreditation Body. He also serves as the Chairman of the
Accreditation Resources Committee for NCSLI.

COURSE
LENGTH AND COST |
Engineers, technicians or anyone responsible to develop uncertainty budgets should attend this
course.
Prerequisites: Students should have a basic technical background, be familiar
with measurement concepts, have a working knowledge of high school algebra, and be familiar with
the Windows operating system and Microsoft Excel. Statistics knowledge is helpful but NOT
required; we will provide the necessary training and understanding of the applicable statistics
concepts. |

WHAT'S
COVERED |
Prior to class, students will receive a copy of the book written by the instructor,
"Measurement Uncertainty Analysis Fundamentals" (a $125 value).
This is to be read prior to class to ensure maximum benefit of time spent in class.
During class, students will receive a CD loaded with tools for unit conversion, calibration
interval evaluation, Quametec's "Uncertainty Toolbox™ for Microsoft Excel®
" (a $195 value), plus reference documents for advanced learning, and a FREEWARE
digital electronic statistics textbook.
COURSE OUTLINE
The course includes instruction in the principles of uncertainty analysis and hands-on training
in the specific analysis problems relevant to the students' workplace.

Example Problems
Solving Uncertainty Analysis Problems relative to Student's Workplace and other examples.
Part 3 - Laboratory Scope of Capability

- Maintaining your Scope's Correctness
The Measurement Uncertainty Class' Unique Guarantee
"If after taking our class you have difficulty computing a measurement uncertainty, we
will provide additional training at no additional cost via email and telephone." Many
of our students had previously taken the two-day "concept classes" offered by others
and walked away with only a nodding acquaintance of the process. At the completion of our
course, you will be able to return to your work center with the capability to perform
measurement uncertainty analyses, not just have some vague idea of how it is done! This course
covers two major objectives: learn the concepts of measurement uncertainty analysis and get
hands-on experience in computing practical examples from numerous measurement disciplines. |
