Bytest testing for aerospace

Bytest is an outstanding company in the Non-Destructive Tests, Material testing and Advisory services for a diverse range of indutries and its background of inspections and experience goes way back to 30 years ago when it was first established. Bytest is now part of the TÜV SÜD Group since 2012, we are a reference for industrial testing as well as a recognized leading company in the NDT field

Bytest has two main headquarters: the first one based in the new and modern hub in Volpiano, Turin, which is NADCAP and MTL (Material Testing Lab) accredited, on the other hand the Benevento facility, near Naples, NADCAP and Boeing accredited.

As far as NDT concerns, we can provide you with a wide spectrum of inspections, ranging from Ultrasound Inspection, Radiography, Computed Tomography and Magnetic Inspection, Eddy Current, Penetrant fluorescent liquids, Cleaning and Contamination Test. As for the destructive part, we are able to support our client with a large variety of testing, for example alloy identification, thermography, visual inspection, metallographic replicas, and field hardness testing, just to mention a few.

Bytest is ISO 9001 and AS 9100 certified, the latter refers to the specific Quality Management System for companies manufacturing systems, equipment and original components for the Aerospace industry and suppliers of the TIC industry.

Bytest is certified by prestigious customers in the Aerospace industry for the main testing services click here to see the certifications.
