The purpose of ISO 11699-1 is to establish the performance of film systems.ISO 11699-1 is applicable for the classification of film systems in combination with specified lead screens for industrial radiography (non-destructive testing). ISO 11699-1 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 International Standards such as ISO 5579, ISO 17636 and EN 12681.ISO 11699-1:2008 does not apply to the classification of films used with fluorescent intensifying screens. The measurement of film systems in ISO 11699-1:2008 is restricted to a selected radiation
