Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

If an accelerated corrosion test was carried out on the whole anode, xstm this area would be consumed at a faster rate than the remainder of the anode. These changes could include changes in the films or processing chemicals used, changes in the dies or printing for the cardboard mats, etc.

Subscription pricing is determined by: Called Type 2 in previous revisions. The table below represents the most up to date summary for assessing the design life against the x-ray level acceptance criteria. This standard is not included in any packages.

These changes could include atsm in the films or processing chemicals used, changes in the dies or printing for the cardboard mats, etc. This is the same for level 4 and 5 as these flaws are increasing and the design life will be dramatically shortened. We have previously been the only manufacturer exclusively supplying tubular anodes to the Durichlor 51 Anode company.

The only tooling that is required to make these connections are 2 torque wrenches 1. If the document is revised or amended, you will be notified by email.

Following is a list of discontinuity categories, types and severity levels for the adjunct reference radiographs of this standard: 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. This slower cooling rate not only causes an inferior grain 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 change in section.

These connections can be made in the factory or in the eld.

The reference radiograph films are an adjunct to this document and must be purchased s186 from ASTM International, if needed see 2. Each volume consists of three categories of graded discontinuities in increasing severity levels, and three categories of ungraded discontinuities.

The x-ray acceptance criteria should and does take e168 to account both the size, frequency and type of defect present. Please first log in with a verified email before subscribing to alerts.

This x-ray shows our centrifugally-cast anode.

ASTM E – 15 Standard Reference Radiographs for Ductile Iron Castings

Categories and severity levels for each discontinuity type represented by these reference radiographs are described in 1. The basis of application for these reference radiographs requires a prior purchaser supplier agreement of radiographic examination attributes and classification criterion as described in Sections 45and 6 of this standard. 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.

In the image, this area has been de ned as a level 3 defect. Even though the silicon iron material retains gas porosity, if the anodes are produced to level 3 then there are additional flaws in the manufacturing procedure which are quantifiable and ideally should not be accepted.

By examining the quality of levels 1 to 5 that are displayed by anodes you w186 able to understand how the theoretical life design of the anode system will be affected. Cancel reply Post comment. Likewise, if a mechanical test bar was machined out of this section of the casting, the results would fall far short of those exhibited by any section of the centrifugally-cast anode. We have retained these pieces for further testing by any interested party, if so desired.
