International School of Aerospace NDT Limited
Radiographic Film Interpretation for NDT Inspectors
(40 hour/5 day Course)
This Level I/II course satisfies the syllabus requirements of ASNT-CP-189, SNT-TC-1A, NAS 410 and ISO 9712. 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 and 2
- Exposure variables - practical exercises on exposure, processing variables, practical exercises on processing, manual and automatic, sensitivity contrast, specimen density changes, quality radiation, kV circuits (BW).
- Processing - developer types, strengths, thickness.
- Types of film, lead screens.
- Definition - geometric sharpness, movement unsharpness, type of film, salt screens.
Days 3 to 5
- Conditions for interpretation, non-destructive tests, standards, codes and specifications, visual acuity, radiographic viewing conditions and equipment, high intensity illuminators, magnifiers, other viewing accessories.
- Indications description, false indications (film artefacts), artefacts caused prior/after processing and discontinuity indications.
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.
