Use of Pooled Standard Deviation of Paired Samples in Calculating the Measurement Uncertainty by the Monte Carlo Method

Abstract

Abstract. This paper presents guidelines for expression of measurement uncertainty for tensile tests (tensile strength), making the Type A evaluation of uncertainty from historical data. The application of pooled standard deviation obtained from several samples and calculated on the values obtained for tensile strength, helps for a better expression of uncertainty in measurement. Accordingly, the results obtained with GUM and Monte Carlo evaluation methods were consistent.
