The first training unit introduces the subject of Metrology, with a particular focus on issues related to the Quality data and information available, for which the concept of “Uncertainty” is key and never completely divisible from the very same act of measurement, but can be put under control if both directly controllable and external conditions are known and its influence properly analysed.
This element introduces aspects to combat Uncertainty in the Industry, first of all by refreshing the fundamental units of the International System, and then by presenting the Destructive (e.g. tensile, torsion or hardness testing) and Non-Destructive Test methods such as Ultrasonic, X-Ray Computerized Tomography, or even Optical techniques for surface inspection. An introduction to the physical principles of measurement and transformation is given finally; again, by stressing the correspondent error sources in each of the cases.
