ASTM E1734-16

Standard Practice for Radioscopic Examination of Castings

SIGNIFICANCE AND USE
4.1 The requirements in this practice are intended to control the quality of the radioscopic images to produce satisfactory and consistent results. This practice is not intended for controlling the acceptability of the casting. The radioscopic method may be used for detecting volumetric discontinuities and density variations that are within the sensitivity range of this practice. The dynamic aspects of radioscopy are useful for maximizing defect response.
SCOPE
1.1 This practice covers a uniform procedure for radioscopic examination of castings. Radioscopic examination of weldments can be found in E1416.  
1.2 This practice applies only to radioscopic examination in which an image is finally presented on a display screen (monitor) for evaluation. Test part acceptance may be based on a static or dynamic image. The examination results may be recorded for later review. This practice does not apply to fully automated systems in which evaluation is performed automatically by a computer.  
1.3 Due to the many complex geometries and part configurations inherent with castings, it is necessary to recognize the potential limitations associated with obtaining complete radioscopic coverage. Consideration shall be given to areas where geometry or part configuration does not allow for complete radioscopic coverage.  
1.4 The values stated in inch-pound units are to be regarded as the standard. The SI units given in parentheses are for information only.  
1.5 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.
