DIN EN ISO 11699-1:2012-01

The purpose of Part 1 of DIN EN ISO 11699 is to establish the performance of film systems.This document is applicable for the classification of film systems in combination with specified lead screens for industrial radiography (non-destructive testing). This document 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.This document does not apply to the classification of films used with fluorescent intensifying screens.The measurement of film systems in this document 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.
