Description of ASTM-E689 2010ASTM E689 - 10Standard Reference Radiographs for Ductile Iron CastingsActive Standard ASTM E689 | Developed by Subcommittee: E07.02 Book of Standards Volume: 03.03 ASTM E689Significance and Use The casting process has demonstrated radiographic similarities between internal discontinuities for ductile cast iron and cast steel to the extent that the reference radiographs for steel castings are applicable. 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. When employing steel casting reference radiographs to evaluate ductile iron castings, the applicable E446 , E186 , or E280 steel casting written standard shall also be used for specific guidance and evaluation procedures. These reference radiographs are intended as a basis from which manufacturers and purchasers may, by mutual agreement, select particular discontinuity classes to serve as standards representing minimum levels of acceptability. 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 1.1 This standard extends the application of steel casting reference radiographs E446 , E186 , and E280 to ductile iron castings when determined appropriate for specific applications (see Section 4). 1.2 The reference radiograph films are an adjunct to E446 , E186 , or E280 , 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 1The 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 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.
