Course Objectives
The validity of absolute measurements has little meaning unless the uncertainty of the equipment used to perform the task is known. ISO/QS-9000 and ISO/IEC 17025 require that the uncertainty of measurement is taken into account when performing calibration activities. This course provides attendees with an understanding of the requirements of the ISO Guide to The Expression of Uncertainty in Measurement which defines methodologies to calculate uncertainty.

Who Should Attend
  • Quality managers
  • Quality and design engineers
  • Laboratory and technical personnel who are responsible for calibration laboratories, establishing uncertainty or evaluation
  • Those involved in the assessment of calibration systems within organizations


Prerequisites
A basic knowledge of math and statistical techniques and the concept of traceability of measurement to national/international standards is recommended.
