Hardness testing devices with UCI measuring technology from NewSonic

NewSonic’s hardness testing devices test hardness in a nondestructive way using the UCI method (ultrasonic contact impedance). The testing procedure enables quick and mobile measurements (1-second type) to supplement traditional hardness testing. The devices feature compact measurement probes which can also be used in difficult testing positions and component geometries. The areas of application include incoming goods inspection, mix-up checks, production controls, quality assurance, weld seam inspection, cut edge checks, maintenance of built-in components, as well as the replacement of dynamic hardness testing devices in the case of thin materials (below 50mm, e.g. boilers, pipes)

The small size and depth of the testing indentation ensures that the test piece can be re-used (with a few exceptions). This is why this procedure can be considered ‘non-destructive’. Further advantages include simple automation functions and high reproducibility. When using the UCI method, the entire contact surface of the Vickers diamonds is included in hardness calculations (not only the diagonal size or diameter as in convention hardness testing). This method is therefore characterised by a lower sensitivity in the event of unsymmetrical test indentations. The procedure is standardised in accordance with DIN 50159 and ASTM A1038.
