United KingdomThe International School of Aerospace NDT Limited is a British Institute of Non Destructive Testing accredited training school for all methods of aerospace NDT, and is recognised as a BINDT approved outside agency, in accordance with the requirements of the UK NANDTB.
ISA NDT is conveniently situated at Norwich International Airport, just a short taxi ride away from Norwich city centre, the thriving historical hub of the east.
With over 50 years of combined experience in the aviation and non-destructive testing industry, the School has an enviable reputation with practical and theoretical testing techniques. Consequently, we travel all over the world to train and certify students, and attract students from all over the world to our premises in the UK.
With our purpose built 200kV Radiographic and Isotope Exposure Room, automatic film processing facilities and laboratories utilising state of the art equipment supplied by leading manufacturers, we make it our priority to offer students hands-on experience with the latest NDT equipment.
Classrooms come equipped with computer and WiFi access, as well as air-conditioning to ensure a comfortable learning atmosphere for all our students.
Light lunches are available in our student lounge, or alternatively in nearby pubs and cafes. As a service to our customers we offer corporate rated accommodation, from guest houses to 5 Star Hotels, accommodation suppliers list is available on request.
“Our aim at ISA is to make learning as enjoyable as possible; student welfare is therefore always of the highest priority.” - Gary Jenkins – Director

Course Details
Course Outcome
(16 hour/2 day Course)
This Level I/II course satisfies the syllabus requirements of ASNT-CP-189, SNT-TC-1A, NAS 410 and PCN. It is suitable for engineering inspectors at all levels of experience who require formal training and a qualification in this subject.
The course will cover radiographic inspection, processing and the varying parameters that contribute to the final radiographic image, together with information on the film interpreter’s role and capability paying particular attention to the interpretation of radiographs.
This Course Comprises:
Days 1
Days 2
At the end of the course students can participate in approval examinations in Radiographic Film Interpretation at Level I or II to SNTC-TC-1A, NAS 410 or ASNT-CP-189 in accordance with their company written practice.
(16 hour/2 day Course)
This is an introductory course in non-destructive testing. It is designed for engineering managers and quality assurance personnel or newcomers to NDT technology who require an in-depth introduction to the subject
The course identifies the practical and management aspects of non-destructive testing. The purpose and limitation of each method is described with practical demonstrations and hands-on sessions to enable the student to objectively understand each method’s reliance on the inspecting technician. NDT reliability is also discussed.
This Course Comprises:
Day 1: Introduction to and objectives of NDT; the nature and origin of defects; liquid penetrant, magnetic particle and eddy current inspection.
Day 2: Ultrasonic inspection and radiographic inspection. Certification of NDT personnel.
(24 hour/3 day Course)
This course is designed for NDT technicians and engineers already practising eddy current inspection requiring a more in depth understanding of impedance plane analysis and involves both theoretical and practical applications allowing the student to gain experience in a wide variety of NDT inspection procedures using this method of NDT.
Ideally the candidate should have attained Level II in eddy current inspection prior to attending this course.
The course comprises:
All students are continually assessed during the course by homework and progress tests together with a theoretical end of course examination.
