1.1 This test method covers determination of the relative image quality response of industrial radiographic film when exposed to X-radiation sources having photon energies from 4 to 25 MeV. Evaluation of the film is based on the visibility of holes in a special image quality indicator (IQI). Since results for a given film type may vary, depending on the particular processing system and processing conditions used, it is essential to state the exposure parameters and achieved density, processing chemistry, processing cycle, and processing temperature. For the purposes of this test method, it is assumed that all components of the X-ray system are operating properly and are capable of producing a given image quality. This test method is not intended to be used for films exposed with Cobalt 60 sources or X-ray sources below 4 MeV.
