1.1The digital reference images provided in the adjuncts to this standard illustrate various types and degrees of discontinuities occurring in titanium castings.2 Use of this standard for the specification or grading of castings requires procurement of the appropriate adjunct digital reference images, which illustrate the discontinuity types and severity levels. They are intended to provide the following:

1.2The digital reference images consist of twenty-five digital files each illustrating eight grades of increasing severity. The Volume I files illustrate seven common discontinuity types representing casting sections up to 1 in. (25.4 mm). The Volume II files illustrate five discontinuity types representing casting sections over 1 in. (25.4 mm) to 2 in. (50.8 mm) in thickness.

1.3All 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.

1.4The 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.

1.5These digital reference images are not intended to illustrate the types or degrees of discontinuities when performing film radiography. If performing film radiography of titanium castings, refer to Reference Radiographs E1320.

1.6This 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.

1.7Only 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.
