1.1 These digital reference images illustrate the types and degrees of discontinuities that may be found in aluminum-alloy castings. The castings illustrated are in thicknesses of 1/ 4 in. [6.35 mm] and 3/4 in. [19.1mm].
1.2 All areas of this standard may be open to agreement between the cognizant engineering organization and the supplier, or specific direction from the cognizant engineering organization. These items should be addressed in the purchase order or the contract.
1.3 The values stated in inch-pound units are to be regarded as standard.
1.4 These digital reference images are not intended to illustrate the types and degrees of discontinuities found in aluminum-alloy castings when performing film radiography. If performing film radiography of aluminum-alloy castings, refer to Reference Radiographs E 155.
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.
1.5 Only licensed copies of the software and images shall be utilized for production inspection. A copy of the ASTM/User license agreement shall be kept on file for audit purposes.Note 1
The set of digital reference images consists of 13 digital files, software to load the desired format and specific instructions on the loading process. The 13 reference images illustrate eight grades of severity and contain an image of a step wedge and two line pair gauges. Refer to Practice E 2002 for line pair gauge details.Note 2
Reference radiographs applicable to aluminum and magnesium die castings up to 1 in. [25 mm] in thickness are contained in Reference Radiographs E 505.
