Presented by the American Association for Laboratory Accreditation (A2LA), this course is suitable for all personnel of both calibration and testing laboratories. Every effort is made to eliminate unnecessary complications, to apply The Guide to the Expression of Uncertainty in Measurement (GUM) at its simplest level and to take away the mystery associated with measurement uncertainty. Participants who have never developed uncertainty budgets usually develop the required skill well before the end of the class. Others who seek explanations of GUM complexities obtain clarifications expressed in simple terms. Measurement uncertainty problems are solved by brainstorming methods so as to generate interaction by all participants.
