Ex 104 - MEASUREMENT UNCERTAINTY - CONFIDENCE IN MEASUREMENT

Overview

The validity of absolute measurements made have little meaning unless the uncertainty of the equipment used to perform the task is known. This TWO-DAY course has been developed to provide people working in the field of measurement with the knowledge to be able to develop uncertainty budgets to meet the requirements of ISO/IEC 17025 and laboratory accreditation bodies.

This course covers the basic statistics required and also provides practical uncertainty exercises and a workshop. All of the exercises are supported with examples of typical uncertainty budgets, which are chosen to cover different fields of measurement.

This can also be run as an in-company ONE or TWO DAY course.

Key Session Topics

• The importance of uncertainty of measurement
  
• Statistics, definitions and terms
  
• Types of distribution
  
• Classification of uncertainties
  
• How to produce and present an uncertainty budget
  
• Degrees of freedom
  
• The 't' distribution table
  
• Sensitivity coefficients
  
• Correlation
  
• Sources of uncertainty in different calibration fields
  
• Uncertainty exercises
  
• Uncertainty workshop

Benefits

• The ability to develop a structured uncertainty budget, including a knowledge of the uncertainty contributions associated with a measurement system and how to evaluate the magnitude of these errors.
• The ability to utilize the results of uncertainty budgets to determine cost and efficiency improvements in measurement systems

Who Should Attend

• Quality and Design Engineers
  
• Laboratory and Technical Personnel
  
• Assessors of quality systems
  
• Assessors of calibration and testing laboratories
  
• Quality and Technical Managers

Although not essential, personnel attending this course should have a basic knowledge of maths and statistical techniques.  Participants should bring a calculator with them which has basic statistical functions.

Course Techniques

This course uses a set of course notes, practical interactive exercises and workshops, through which participants learn about  the development of uncertainty budgets.  Course notes are available for the delegates to retain.

Follow-Up

Consultancy assistance with implementation and auditor programmes can be provided.
