MEASUREMENT PROCESSES ANALYSIS WITH GRR OR EXPANDED UNCERTAINTY? APPLICATION OF CONFIDENCE LEVEL OF 99,73 % OR 95,45%?

Abstract: This paper demonstrates the application of the ISO GUM for analysis of the measurement processes used in the product control. It describes the attention in the method application and the need to establish the acceptability criterion for the measurement process. But also their advantages, such as, the identification of the existent uncertainty sources, the simplification through the sample selection and the application of a confidence level of 95,45%
