Non-destructive-testing – what’s that?

Speaking about material testing a distinction is made between two testing concepts, which determine the quality, purity, freedom from error and resilience of materials and parts, the destructive-testing and the non-destructive-testing. As result of destructive-testing selected testing parts are destroyed or at least altered on the surface. This comes with the disadvantage of losing the partial or complete usability of tested parts. Some of the most common destructive-testing methods are tensile testing, bending testing, hardness testing as well as thermal or chemical tests. In contrast non-destructive-testing (NDT) allows to determine a part’s quality without damaging its material or structure. Well-known examples are visual inspection, radiography testing, ultrasonic testing, acoustic monitoring, penetration testing as well as eddy current testing.

N-DECT develops, produces and distributes individual special precision machines for modern measurement and testing technology and is primarily focused on eddy-current testing (ET) and ultrasonic testing (UT), and extended its knowledge into the areas of Barkhausen Noise Testing (BN), camera surface inspection and dimensional measurement.
