Reference radiographs previously used for this thickness range carried the designation E71but included a now rarely used gamma source, that is, radium. Each set is for comparison only with radiographs produced with equivalent radiation. Where such modifications may be appropriate for the casting application, all such changes shall be specifically called-out in the purchaser supplier agreement or astm e446 document.
Astm e446 and severity levels for each discontinuity type represented by these reference radiographs are described in 1.These changes could include changes in the films or processing chemicals used, changes in the dies astm e446 printing for the cardboard mats, etc. Following is a list of discontinuity categories, types and severity levels for the adjunct reference astm e446 of this standard. Reference radiographs for thicker sections may be found in E and E These reference astm e446 are intended as a basis from which manufacturers and purchasers may, astm e446 mutual agreement, select particular discontinuity classes to serve as standards representing minimum levels of acceptability see Sections 6 and 7.
