More E The exact application and usage of discontinuity classifications contained within steel casting reference radiographs must, however, give consideration to the differences in material properties between cast steel and ductile cast iron. In some applications, reference radiographs for steel castings may not be entirely applicable to ductile cast iron material dependent upon design or other usage criteria. Reference radiographs represented by these steel casting standards may be used, as agreed upon in a purchaser supplier agreement, for radiation energy levels, thicknesses or both outside the range of these standards when determined applicable for the casting service application 1. Scope 1. Categories and severity levels for each discontinuity type represented by these reference radiographs are described within each applicable standard above.

Scope 1. Categories and severity levels for each discontinuity type represented by these reference radiographs are described within each applicable standard above.

These changes could include changes in the films or processing chemicals used, changes in the dies or printing for the cardboard mats, etc. 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. 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.
