Although Category G—Mottling is listed for all three volumes, the appearance of adtm is dependent on the level of radiation energy. Although Category G-Mottling is listed for all three volumes, the appearance of mottling is dependent on astm e astmm of radiation energy. The basis of application for these reference radiographs requires a prior purchaser supplier agreement of radiographic examination attributes and classification criterion as described in Sections 46and 7 of this standard.

SI values are shown for information only. Reference radiographs containing ungraded discontinuities are provided as a guide for recognition of a specific casting discontinuity type where severity levels are not needed. 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 astm e one example of each of these discontinuity types.

However, caution should be used so that the kV is not raised to the point that sensitivity is reduced excessively. It should be recognized that each energy level is not applicable to the entire thickness range covered by this document.

This standard has been approved for use by agencies of the Department of Defense. 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.

When the unit area of interest of a production radiograph is less than the unit area of the applicable reference radiograph, such unit area of the production radiograph shall be prorated to the reference radiographic area.

Reference radiographs previously used e46 this thickness range carried the designation E71but included a now rarely used gamma source, that is, radium. Active view current version of standard Translated Standard: Reference radiographs for thicker sections may be found in Reference Radiograph standards E and E The reference radiographs consist of the following: The current document is also updated by inclusion of several recognized shrinkage ast, C categories and by elimination of the crack and hot tear categories except for one example of each of these discontinuity types.

Each volume consists of six categories of graded discontinuities of increasing severity level and four categories of ungraded discontinuities. Additionally, some overlap of severity levels may occur for discontinuity categories of this standard and similar discontinuity categories of E reference radiographs within the same aastm level range.

We have no amendments or corrections for this standard. Reference Radiograph standards E and E provide e46 overlap of severity levels for similar discontinuity categories within the same energy level range see 4.

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:. Originally approved in Already Subscribed to this document. Active view current version of standard. The radiographs should therefore be periodically examined for signs of wear and tear, including scratches, abrasions, stains, and so forth.
