Unless otherwise specified in a purchaser supplier agreement see 1. Reference radiographs astm e446 used for this thickness range carried the designation E71but included a now rarely used gamma source, that is, radium. Note 2-The illustrations astm e446 of the astm e446 Each set consists of 6 categories of graded discontinuities in increasing severity level and 4 categories of ungraded discontinuites furnished as examples only, as follows:.
Reference radiographs for thicker sections may be found in E and E Although Category G-Mottling is listed for all three volumes, the appearance of mottling is dependent on the level of radiation energy. Each volume consists of six categories of graded discontinuities of increasing severity astm e446 and four categories of ungraded d446.

Where such modifications may be appropriate for the casting application, all such changes shall be specifically called-out in the purchaser supplier agreement or contractual document.
These changes could include changes in the astm e446 or processing chemicals used, changes in the dies or printing for the cardboard mats, etc. The current document is also updated by inclusion of several recognized shrinkage or C categories and by elimination of the crack and hot tear categories except for one example of each of these discontinuity types.
