Testing equipment used in materials science and mechanical engineering plays a critical role in determining the strength, durability, elasticity, and other mechanical properties of materials and finished products. Ensuring high accuracy, repeatability, and stability of measurements requires particular attention to the metrological performance of testing machines. Calibration is a key process for maintaining the reliability of such equipment. It involves the verification and adjustment of force, displacement, and deformation sensors using traceable reference standards to guarantee the validity and precision of the obtained results.
