1.1?These digital reference images illustrate various categories, types, and severity levels of discontinuities that may occur in aluminum-alloy and magnesium-alloy die castings. They are intended to provide:

1.2?These digital reference images consist of nine images covering discontinuities in aluminum and magnesium alloy die castings. Four contain graded sequences of four levels of increasing severity in aluminum castings. Four contain graded sequences of four levels of increasing severity in magnesium castings. The last image contains ungraded illustrations of inclusions in aluminum and magnesium alloy die castings.

1.3?Two kinds of illustration categories are covered as follows:

1.4?This document may be used for other materials, thicknesses or with other energy levels for which it has been found to be applicable and agreement has been reached between purchaser and supplier.

1.5?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.

1.6?These digital reference images are not intended to illustrate the types and degrees of discontinuities found in aluminum and magnesium die castings when performing film radiography. If performing film radiography of aluminum or magnesium die castings, refer to Reference Radiographs E505.

1.7?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. (See Note 2.)

1.8?Units?The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.9?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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.10?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
