Referenceradiograph films are no exception and may exhibit a loss inimage quality over time. The radiographs should therefore beperiodically examined for signs of wear and tear, includingscratches, abrasions, stains, and so forth. Any reference radio-graphs which show signs of excessive wear and tear whichcould influence the interpretation and use of the radiographsshould be replaced.

Basis for Application6. Appli-cation of these reference radiographs as acceptance standardsshould be based on the intended use of the product and thefollowing considerations see Note 3 The sizeof the unit area should be specified in the acceptance criteria.

Discontinuities more severe than those in the specified refer-ence radiograph shall be considered rejectable. Different grades or acceptance limits may be specified for eachdiscontinuity type. Further, different grades may be specifiedfor various regions or zones of the component.

Anymodification of the acceptance criteria required on the basis ofmultiple discontinuity types must be specified. NOTE 3—Caution should be exercised in specifying the acceptancecriteria to be met in the casting.

Casting design coupled with foundrypractice should be considered. It is advisable to consult with themanufacturer or foundry before establishing the acceptance criteria toensure the desired quality level can be achieved. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the riskof infringement of such rights, are entirely their own responsibility.
