Called Type 1 in previous revisions. As the voice of the U.
The x-ray image of the die-cast anode above shows a serious casting aw visible as a dark shadow in the connection area and is a real-life sample con rming the di culties encountered with this design. Historical Version s – view previous versions of standard.
This includes cobalt asym equivalent isotope radiation and from qstm — MV up to aastm — MV X rays- Set of 28 plates nominal 5 by 8 in. Proceed to Checkout Continue Shopping. This is a unique feature of the Centrifugal Casting method and is highly advantageous to the integrity of the casting.
Many companies are now specifying that anodes should be supplied that pass an x-ray test to level 1, level 2 or level 3 ASTM E Need more than one copy? Xstm is the same for level 4 and 5 as these flaws are increasing and the design life will be dramatically shortened.
Called Type 3 in previous revisions. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. Link to Active This link will always route to the current Active version of the standard. It should be noted that the type of defect seen on the x-ray and its position in the casting will further influence the design life.
ASTM E – 15 Standard Reference Radiographs for Ductile Iron Castings
The reference radiograph films are an adjunct to this document and must be purchased separately from ASTM International, if needed see 2. Historical Version s – view previous versions of standard. Following is a list of discontinuity categories, types and severity levels for the adjunct reference radiographs of this standard:. 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.
Reference radiographs containing ungraded discontinuities are provided as a guide for recognition of a specific casting discontinuity type where severity levels are not needed.
Reference radiographs for other steel casting thicknesses may be found in Reference Radiograph standards E and E Following is a list of discontinuity categories, types and severity levels for the adjunct reference radiographs of this standard:. The table below represents the most up to date summary for assessing the design life against the x-ray level acceptance criteria. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
E Reference Radiographs for Heavy-Walled to 12 in. 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. You can adjust all of your cookie settings by navigating the tabs on the left hand side. This is a text-only standard.
These reference radiographs are intended as a basis from which manufacturers and purchasers may, by mutual agreement, select particular discontinuity classes to serve as standards representing minimum levels of acceptability see Sections 6 and 7. You may delete a document from your Alert Profile at any time.
Likewise, if a mechanical test bar was machined out of this section asfm the casting, the results would fall far short of those exhibited by any section of the centrifugally-cast anode.

In some applications, reference radiographs for steel castings may not be entirely applicable to ductile cast iron material dependent upon design or other usage criteria. Reference Radiograph standards E and E provide some overlap of severity levels for similar discontinuity categories within the same energy level range see 4.
Reference radiographs represented by these steel casting standards may be used, as agreed upon in a purchaser supplier agreement, for radiation energy levels, thicknesses or both outside the range of these standards when determined applicable for the 1e86 service application.
