This is a text-only standard. This standard extends the application of steel casting reference radiographs E, E, and E The reference radiograph films. This standard is issued under the fixed designation E ; the number 1 These reference radiographs are under the jurisdiction of ASTM Committee. E-7 on.

Reference Radiograph standards E and E provide some overlap of severity levels for similar discontinuity categories within the same energy level range see 4. We have retained these pieces for further testing by any interested party, if so desired.
This change in section is an inherent weakness in the design of a die-cast anode because the change in wall thickness means the thicker part of the casting cools more slowly than the narrow section.

Reference radiographs for other steel casting thicknesses may be found in Reference Radiograph standards E and E However, the size and frequency of these flaws are sufficiently small so their existence does not immediately require the need for the casting to be scrapped.
Standards Subsctiption may be the perfect solution. At level 2 for the acceptance criteria, there are some specific flaws that will influence the overall life of the anode. Powered by GDPR plugin. The reference radiograph films are an adjunct to this document and must be purchased separately from ASTM International, if needed see 2. We have 3 XRF chemical analysis machines in both the UK and China and our pricing re ects the signi cant disparity between production costs when comparing astk production costs in China to those in North America.
Where such modifications may be appropriate for the casting application, all such changes shall be specifically called-out asgm the purchaser supplier agreement or contractual document. The x-ray acceptance criteria should and does take in to account both the size, frequency and type of defect present.
This is a unique feature of the Centrifugal Casting method and is highly advantageous to the integrity of the casting. Reference radiographs containing ashm discontinuities are provided as a guide for recognition of a specific casting discontinuity type where severity levels are not needed. Called Type 1 in previous revisions 2 Cb — feathery shrinkage — Severity levels 1 through 5. You can adjust all of your cookie settings by navigating the tabs on the left hand side.
This chart shows a comparison in sizes between Specialist Castings Anodes and other common anode sizes. These are our key findings.
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 casting service application. Called Type 3 in previous revisions.
