Historical Standard: ASTM E746-02 Standard Test Method for Determining Relative Image Quality Response of Industrial Radiographic Film
SUPERSEDED (see Active link, below)
ASTM E746
1. Scope
1.1 This test method covers the determination of the relative image quality response of industrial radiographic film when exposed to 200-kV X rays. The evaluation of the film is based upon the threshold visibility of penetrameter holes in a special image quality indicator (IQI). Results for a given film type may vary, depending upon the particular development system used. It is, therefore, necessary to state the development system and geometric conditions used in this determination. By holding the technique parameters (except exposure time) and processing parameters constant, the image quality response of radiographic film may be evaluated on a relative basis.
1.2 Alternately this test method may be used for determination of the relative image quality response of a radiographic film when exposed to 200-KV X-rays as any other single component of the system (such as screens) is varied.
1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
