scope:

The purpose of this standard is the fixation of 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). It shall be achieved by this standard that the image quality of radiographs - as far as this is influenced by the film system - fulfils certain minimum requirements. These minimum requirements correspond to system classes as requested by test specifications and standards, i.e. prEN 444. The evaluation of films used with fluorescent intensifying screens is not specified in this european standard. Additionally to the methods of quantitative measurement described in part 1 of this standard, image quality evaluation methods are described in part 2 (to be considered) by which the quality of film systems can be controlled under the conditions given in industrial application.
