This 2-day course will review the basic concepts and the accreditation requirements associated with measurement traceability, measurement assurance and measurement uncertainty as well as discuss the interrelationship between the three. A basic process for the effective evaluation of a calibration service supplier or reference material producer will be discussed and, through a practical exercise, participants will apply the process. Metrology terminology and basic statistics, including a discussion on probability density functions and how they are used to quantify an uncertainty component, will be introduced. Additionally, the NIST 8-Step Process for Estimating and Reporting Measurement Uncertainty which provides a general framework for estimating measurement uncertainty, will be presented. Participants will then put their newly acquired knowledge into practice with practical exercises on establishing an uncertainty budget and estimating measurement uncertainty. Lastly, the course will conclude with a discussion on the importance of having sufficient knowledge on these topics regarding the purpose and scientific concepts for effective testimony.
