Historical Version s – view previous versions of standard. Reference radiographs containing ungraded discontinuities are provided as a guide for recognition of a specific casting discontinuity type where severity levels may not be needed.
ASTM E – 15 Standard Reference Radiographs for Ductile Iron Castings
These reference radiographs are intended as a asgm from which manufacturers and purchasers may, by mutual agreement, select particular discontinuity classes to serve as standards representing minimum levels of acceptability see Sections astk and 7. Severity levels of similar discontinuity categories and energy level range of E or E reference radiographs may alternatively be used, as determined appropriate for the casting service application, if so agreed upon in a purchaser supplier agreement see Section 1 and 5.
Where such asstm may be appropriate for the casting application, all such changes shall be specifically called-out in the purchaser supplier agreement or contractual document. Section 9 addresses purchaser supplier requisites where weld repairs to castings may be required. The reference radiograph films are an adjunct to this document and must be purchased separately from ASTM International, if needed see 2.
Categories and severity levels for each discontinuity type represented by these reference radiographs are described in 1.
Reference asgm for other steel casting thicknesses may be found in Reference Radiograph standards E and E Reference Radiograph standards E and E provide some overlap of severity levels for similar discontinuity aetm within the same energy level range see 4.
This includes cobalt or equivalent isotope radiation and from 2—MV up to 4—MV X-rays- Set of 28 plates nominal 5 by 8 in. Each volume consists of three qstm of graded discontinuities in increasing severity levels, and three categories of ungraded discontinuities. Reference radiographs containing ungraded discontinuities are provided as a guide for recognition of a specific casting discontinuity type where severity levels are not needed.
Following is a list of discontinuity categories, types and severity levels for the adjunct reference radiographs of this standard:. Called Type 1 in previous revisions. Called Type 2 in previous revisions.

Called Type 3 in previous revisions. These changes could include changes in the films or processing chemicals used, changes in the dies or printing for the cardboard mats, etc. Therefore, the adjunct reference radiographs remain valid for use with this standard regardless of the date of production or the revision level of the text standard.
