The purpose of this standard is to establish the performance of film systems. This standard is applicable for the classification of film systems in combination with specified lead screens for industrial radiography (non-destructive testing). The standard is intended to ensure that the image quality of radiographs - as far as this is influenced by the film system - is in conformity with the requirements of European Standards such as ISO 5579, ISO 17636 and EN 12681. This European Standard does not apply to the classification of films used with fluorescent intensifying screens. The measurement of film systems in this standard is restricted to a selected radiation quality to simplify the procedure. The properties of films will change with radiation energy, but not the ranking of film system quality. Additional methods for evaluating the photographic process are described in EN ISO 11699-2, by which the performance of film systems can be controlled under the conditions given in industry. The responsible German committee is NA 062-08-22 AA "Durchstrahlungsprüfung und Strahlenschutz" ("Radiation methods and radiation protection") of the Materials Testing Standards Committee (NMP).
