These connections can be made in the factory or in the eld. Each volume consists of three categories of graded discontinuities in increasing severity levels, and three categories of ungraded discontinuities. These changes could include changes in the films or processing chemicals used, changes in the dies or printing for the cardboard mats, etc.
Reference radiographs for other steel casting thicknesses sstm be found in Reference Radiograph standards E and E Additionally, the centrifugally cast anode utilises a straight-walled anode design that has no change in cross section or thickness at the centre of the anode and no complex arrangement of sand cores die cast anodes require up to 10 sand cores per anode which are susceptible to individual discrepancies between every casting.
This standard extends the application of steel casting reference e86 E, E, and E This standard is also available to be included in Standards Subscriptions. Cancel reply Post comment.
ASTM E – 15 Standard Reference Radiographs for Ductile Iron Castings
You can adjust axtm of your cookie settings by navigating the tabs on the left hand side. 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. The exact application and usage of discontinuity classifications contained within steel casting reference radiographs must, however, give consideration to the differences in material properties between cast steel and ductile cast iron.
We have no amendments or corrections for this standard.

A direct comparison of Centrifugally Cast Tubular Anodes and Die Cast Tubular Anodes
Already Subscribed to this document. This x-ray shows our centrifugally-cast anode. Historical Version s – view previous versions of standard. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
Active view current version of standard. Categories and severity levels for each discontinuity type represented by these reference radiographs are described in 1. Called Type 3 in previous revisions. 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.
Following is a list of discontinuity categories, types and severity levels for the adjunct reference radiographs of this standard: The reference radiograph films are an adjunct to this document and must be purchased separately from ASTM International, if needed see 2.
We have previously been the only manufacturer exclusively supplying tubular anodes to the Durichlor 51 Anode company.
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.
This is a text-only standard.
Please first verify your email before subscribing to alerts. 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.
Following is a list of discontinuity categories, types and severity levels for the adjunct reference radiographs of this standard: This is the same for level 4 and 5 as these flaws are increasing and the design life will be dramatically shortened.
The values given in parentheses are mathematical conversions to Sstm units that are provided for information only and are not considered standard.
Referenced Documents purchase separately The documents asm below are referenced within the subject standard but are not provided as part of the standard. Reference Radiograph standards E and E provide some overlap of severity levels for similar discontinuity categories within the same energy level range see 4. This slower cooling rate not only causes an inferior e168 structure that is almost as poor as sand-cast anodes, but also necessitates an additional riser to help feed the shrinkage that is catalysed from the astj in section.
Called Type 1 in previous revisions. Reference radiographs containing ungraded discontinuities are provided as a guide for recognition of a specific casting discontinuity type where severity levels are not needed.
