Non-destructive testing - Industrial radiographic film - Part 1: Classification of film systems for industrial radiography 1 Scope The purpose of this part of GB/T 19348 is to establish the performance of film systems. This part is applicable for the classification of film systems in combination with specified lead screens for industrial radiography (non-destructive testing). This part 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 other standards such as ISO 5579, ISO 17636 and EN 12681. This part does not apply to the classification of films used with fluorescent intensifying screens. The measurement of film systems in this part 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 GB/T 19348.2, by which the performance of film systems may be controlled under the conditions given in industry. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
