Abstract

The specification of mechanical properties is essential for adequate choice of material, as well as for design and manufacturing of components and products. recognised that the present state of uncertainties in testing activities is not as comprehensive as in the calibration fields. This paper presents guidelines calculation of measurement uncertainty (tensile strength and percentage elongation after fracture making the type A evaluation from historical data. also demonstrated that the application of deviation has larger representativeness than the use of diameter and load standard deviations.
