Term
Traditional NDT A certified inspector performs an inspection
of an object on-site according to a
inspection procedure.
Remote NDT A certified inspector performs an inspection
of a remotely located object, according to
an inspection procedure, with the
assistance of one or more helpers at the
site of the object, and aided by realtime
video-, sound- and NDT data transferred
over a communication channel.
Simplified NDT An individual with neccessary training
performs an inspection with the use of a
procedure, supporting technology and
clearly defined acceptance criterias.

Expected market development
Traditional NDT + R&D market develops with CFRP use.
Manufacturing
• Quick check tool for borehole inspection, bond testing, accidental damages
• Inline manufacturing: will be low volume, tailored, project delivery and needs a dedicated business model.
Remote and Simplified NDT scales with
• Cost focus; salaries, training, travel and equipment
• Rollout of planned cars/aircraft
• Increasing level of integration between manufacturers, maintenance organizations and service providers.
• Regulatory changes
