1.1 This standard extends the application of steel casting reference radiographs , , and to ductile iron castings when determined appropriate for specific applications (see Section ).
1.2 The reference radiograph films are an adjunct to , , or , and must be purchased separately from ASTM International, if needed (see ). 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 , , and 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 and health practices and determine the applicability of regulatory limitations prior to use.
