On-site Public Training Sessions
These training sessions are conducted at an on-site facility open to the public. These cover various aspects of ISO/IEC 17025:2017. Participants have the opportunity to exchange experiences and learn from other participants. Hands on training are provided by an experienced trainer from the laboratory and accreditation industry.
2018 Training Schedule
Measurement Uncertainty and Development of Uncertainty Budgets
June 18th & 19th, 2018
During the course of instruction the following activities will take place:
Review of the measurement uncertainty requirements found in the following documents:
• ISO/IEC 17025:2005 & 2017
• ILAC P14
• JCGM 100:2008 “the GUM”
• A representative example uncertainty policy from an accreditation body
• Introduce and define metrological terms related to measurement uncertainty
• Illustrate the 4 different scenarios in which measurement uncertainty occurs
• Identify common ways in which measurement results are distributed
• Demonstrate use of the “T” distribution when working with small samples
• Use the Welch–Satterthwaite equation to calculate the “Effective Degrees of Freedom” when combining standard uncertainties from several sources
• Identify the necessary steps in developing an estimate of measurement uncertainty
Upon completion of the course, attendees will be able to:
• Identify significant contributors
• Determine the appropriate divisor used to calculate standard uncertainty based on the manner in which the measurement results are distributed
• Calculate the standard uncertainty for each contributor
• Calculate the “Effective Degrees of Freedom” for each contributor
• Prepare an MS Excel based uncertainty budget specific to their needs
• Add basic spreadsheet automation to accelerate the process of uncertainty estimation
*The class is intended for laboratory managers, calibration technicians, assessors, consultants and anyone with the need for a more in-depth and comprehensive understanding of measurement uncertainty.*
Attendees will receive hard copies of all training materials and a memory stick containing all uncertainty budgets developed during the class.
The class will be taught by Henry L. Alexander CMfgE CQE. Henry is the former PJLA Calibration Program Manager and is an active accessor of the ISO/IEC 17025:2005 and 2017 standards. He has been the owner of Henry Alexander Engineering, Inc. since 1989 specializing in the design of dedicated inspection gages and accredited dimensional calibration and inspection services. He has taught numerous classes on measurement uncertainty and internal auditing of the 17025:2005 and 2017 standards. In addition Henry has presented several papers on metrology related topics at NCSLI regional and national events.
The class will be held in training rooms at Calvary Baptist Church in Norwalk, OH and lunch will be provided by PJLA both days.
