ICS Number Code I medium voltage nominal kV X rays. Last previous edition approved in as E — 98 ? In preparing these reference radiographs, the objective was to obtain progressively graduated severity levels for each graded discontinuity category of this standard. The current document is also updated by inclusion of several recognized shrinkage or C categories and by elimination of the crack and hot atsm categories except for one example of each of these discontinuity types.

Note 1-Reference radiographs previously used aastm this thickness range carried the designation E71, but included a now rarely used gamma source, that is, radium.

When this condition occurs in a production radiograph, it shall be evaluated by comparison with the most representative reference radiograph. Need more than one copy? We have no amendments or corrections for this standard.

Production radiographs showing shrinkage shall be judged by the most representative reference radiograph. Where such modifications may be appropriate for the casting application, all such changes shall be specifically called-out in asfm purchaser supplier agreement or contractual document.

The diffraction mottling pattern shown in these cases is dependent principally upon the crystal geometry and the orientation of the crystals to the incident radiation.

Note 3-Although Category G-Mottling is listed for all three volumes, the appearance of mottling is dependent on the level of radiation energy. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of e44 of such rights, are entirely their astj responsibility.

If the production radiograph shows discontinuities of greater severity than the reference radiograph, that part of the casting shall be rejected. SI values are shown for information only. Each set is for comparison only with radiographs produced with equivalent radiation.
