We have no amendments or corrections for this standard. The only tooling that is required to make these connections are 2 torque wrenches 1. Link to Active This link will always route to the current Active version of the standard.
ICS Number Code R186 volume consists of three categories of graded discontinuities in increasing severity levels, and three categories of ungraded discontinuities.
In the top x-ray of the die-cast anode dark circular shadows depicting sub-surface shrinkage can be seen around the area of the pouring cup, i. This is a unique feature of the Centrifugal Casting method and is highly advantageous to the integrity of the casting. Called Type 2 in previous revisions. Link to Active This link will always route to the current Active version of the standard.
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.
These connections can be made in the factory or in the eld. We have anodes stocked in 2 locations in the USA, utilising purpose-made connectors that have been used in over 1 million anodes over the last 35 years see g 4 for TA2 and TA5A connectors.
This standard is also available to be included in Standards Subscriptions. This is a text-only 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. These are our key findings.

Following is a list of discontinuity categories, types and severity levels for the adjunct reference radiographs of this standard: Categories and severity levels for each discontinuity type represented by these reference radiographs are described within each applicable standard above.
The x-ray acceptance criteria should and does take adtm to account both the size, frequency and type of defect present. In the image, this area has been de ned as a level 3 defect. At level 2 for the acceptance criteria, there are some specific flaws that will influence the overall life of the anode.
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.

Each volume consists of three categories of graded discontinuities in increasing severity levels, and three categories of ungraded discontinuities. If you disable this cookie, we will not be able to save your preferences. Called Ast, 3 in previous revisions.

E18 to Alert PDF. 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 e86 quantifiable and ideally should not be accepted. Strictly Necessary Cookie should be enabled at all times so that we can save your preferences for cookie settings. Proceed to Checkout Continue Shopping. 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.
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. 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.
Reference radiographs for other steel casting thicknesses may be found in Reference Radiograph standards E and E Section 9 addresses purchaser supplier requisites where weld repairs to castings may be required.
This is the same for level 4 and 5 as these flaws are increasing and the design life will be dramatically shortened. Severity levels of similar discontinuity categories and energy level range of E ee186 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.
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.
The reference radiograph films are an adjunct to this document and must be purchased separately from ASTM International, if needed see 2.

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 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.
