Radiographic image quality indicators for non-destructive testing — Principles and identification

The detection of an imperfection in a product subjected to X or gamma radiography depends on the quality of the resultant radiograph. This quality should be checked with an image quality indicator. This International Standard is intended for general application on all metals. However, for particular materials (for example, aluminium and its alloys) complementary International Standards may be used.
