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.
