1.1 This document describes the appearance of a radiographic image where fundamental components of image quality are changed, that is, variables such as whether a X-ray or gamma ray source was used, the characteristics of the radiographic film and intensifying screens, and the geometrical configuration of the object under investigation as well as its associated radiographic set-up.

1.2 These reference radiographs consist of four composite illustrations and show how such factors as radiation energy, specimen thickness, and film properties affect the radiographic image.

1.3 The values stated in inch-pound units are to be regarded as the standard.

1.4 This standard does not purport to address all of the safety concerns, 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.
