We have no amendments or corrections for this standard. Your Alert Profile lists the documents that will be monitored. Reference radiographs containing ungraded discontinuities are provided as a guide for recognition of a specific casting discontinuity type where severity levels are not needed.

Each volume consists of three categories of graded discontinuities in increasing severity levels, and three categories of ungraded discontinuities.

ASTM E – 15 Standard Reference Radiographs for Ductile Iron Castings

Although it is not economically viable to carry out an x-ray test on every anode, it is possible to demand that anodes supplied should pass an x-ray criteria level such as level 2 or better and that a percentage of anodes should be tested. The x-ray image of the die-cast anode above shows a serious casting aw visible as a dark shadow in the connection area and is a real-life sample con rming the di culties encountered with this design.

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.

The x-ray acceptance criteria should and does take in to account both the size, frequency and type of defect present. E Reference Radiographs for Heavy-Walled to 12 in. Link to Active This link will always route to the current Active version of the standard. 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 changes could include changes in the films or processing chemicals used, changes in the dies or printing for the cardboard mats, etc. If the document is revised or amended, you will be notified by email. The reference radiograph films are an adjunct to this document and must be purchased separately from ASTM International, if needed see 2.

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. 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 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.

Cancel reply Post comment. 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. Categories and severity levels for each discontinuity type represented by these reference radiographs are described in 1. 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.

Categories and severity levels for each discontinuity type represented by these reference radiographs are described in 1. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

We have retained these pieces for further testing by any interested party, if so desired. You can adjust all of your cookie settings by navigating the tabs on the left hand side. At ee186 criteria level 3 the casting may not perform correctly. In the image, this area has been de ned as a level 3 defect.

These are our key findings. Link to Active This link will always route to the current Active version of the standard. 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. 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.

Therefore, generally defining the overall integrity of the casting. These changes could include changes in the films or processing chemicals used, changes in the dies or printing for the cardboard mats, etc. Reference Radiograph standards E and E provide some overlap of severity levels for similar discontinuity categories within the same energy level range see astmm.

Following is a list of discontinuity categories, types and severity asstm 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.

Reference radiographs for other steel casting thicknesses may be found in Reference Radiograph standards E and E 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.

Reference Radiograph standards E and E provide some overlap of severity levels for similar discontinuity categories within the same energy level range see 4. By taking x-ray shots along the length of the casting to ASTM E94 e18 is possible to view images of the structure. Standards Subsctiption may be the perfect solution. Enable All Save Settings.

The only tooling that is required to make these connections are 2 torque wrenches 1. 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. These reference radiographs are intended as a basis from which manufacturers and purchasers may, by mutual e1186, select particular discontinuity classes to serve as standards representing minimum levels of acceptability see Sections 6 and 7.

Reference Radiograph standards E and E provide f186 overlap of severity levels for similar discontinuity categories within the same energy level range see 4.
