ASTM E689
Scope
1.1 This standard extends the application of steel casting Reference Radiographs E446, E186, and E280 when performing film radiography and Digital Reference Images E2868 and
E3030 when performing digital radiography to ductile iron castings when determined appropriate for specific applications (see Section 4).
1.2 The reference radiograph films are an adjunct to Reference Radiographs E446, E186, or E280, and must be purchased separately from ASTM International, if needed. Likewise, when performing digital
radiography, the digital reference images are an adjunct to Digital Reference Images E2868 and E3030 and must be
purchased separately from ASTM International, if needed (see 2.1). Categories and severity levels for each discontinuity type represented by these
reference radiographs are described within each applicable standard above.
Note 1: The basis of application for these reference radiographs requires a prior purchaser
supplier agreement of radiographic examination attributes and classification criterion as described in Sections 4, 5, and 6 of this standard.
1.3 From time to time, there may be minor changes to the process for manufacturing of the reference radiograph adjunct materials. These changes could
include changes in the films or processing chemicals used, changes in the dies or printing for the cardboard mats, etc.; however, in all cases, these changes are reviewed by the Illustration
Monitoring Subcommittee and all reference radiographs are reviewed against a fixed prototype image to ensure that there are no changes to the acceptance level represented by the reference
radiographs. Therefore, the adjunct reference radiographs remain valid for use with this standard regardless of the date of production or the revision level of the text 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 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.
