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 foundry production costs in China to those in North America.

Following is a list of discontinuity categories, types and severity levels for the e86 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.

A direct comparison of Centrifugally Cast Tubular Anodes and Die Cast Tubular Anodes

Called Type 3 in previous revisions. Following is a list of discontinuity categories, types and severity levels for the adjunct reference radiographs of this standard:. If an accelerated corrosion test was carried out on the whole anode, then this area would be consumed at a faster rate than the remainder of the anode.

Reference radiographs for other steel casting thicknesses may be found in Reference Radiograph standards E and E Categories asrm severity levels for each discontinuity type represented by these reference radiographs are described in 1. Following is a list of discontinuity categories, types and severity levels for the adjunct reference radiographs of this standard: Some companies, such as the ENI Group simply state their refusal to accept any anodes that are below level 3 and other companies have based their design life on their own experience and installations.

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. We have no amendments or corrections for this standard. Reference Radiograph standards E and E provide some overlap of severity levels asttm similar discontinuity categories within the same energy level range see 4. This standard is also available to be included in Standards Subscriptions.

Cancel reply Post comment. Called Type 2 in previous revisions 3 Cc — sponge shrinkage — Severity levels 1 through 5. Proceed to Checkout Continue Shopping.

The reference radiograph films are astj adjunct to this document and must be purchased separately from ASTM International, if needed see 2. This x-ray shows our centrifugally-cast anode.

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.

These connections can be made in the factory or in the eld. SI values are shown for information only. Reference radiographs for other steel casting thicknesses may be found in Reference Radiograph standards E and E Categories and severity levels for each discontinuity type represented by these reference asgm are described within each applicable standard above.

Your Alert Profile lists the documents that will be monitored. Likewise, if a mechanical test bar was machined out of aatm section of the casting, the results would fall far short of those exhibited by any section of the centrifugally-cast anode.

This standard extends the application of steel casting reference radiographs E, E, and E The reference radiograph films are an adjunct to this document and must be purchased separately from ASTM International, if needed see 2.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM E – 15 Standard Reference Radiographs for Ductile Iron Castings

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. This website uses cookies so that we can provide you with the best user experience possible. This is the same for level 4 and 5 as these flaws are increasing and the design life will be dramatically shortened. Already Subscribed to this 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.

Called Type 1 aatm previous revisions 2 Cb — feathery shrinkage — Severity levels 1 through 5. By taking x-ray shots along the length of the casting to ASTM E94 it is possible to view images of the structure. By examining the quality of levels 1 to 5 that are displayed by anodes you are able to understand how the theoretical life design of the anode system will be affected.

You can adjust all of your cookie settings by navigating the tabs on the left asstm side. 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.
