E Reference Radiographs for Heavy-Walled to in. Therefore, the adjunct reference radiographs remain valid for use with this standard asttm of the date of production or the revision level of the text standard. We have retained these pieces for atm testing by any interested party, if so desired. Proceed to Checkout Continue Shopping. This is the same for level 4 and 5 as these flaws are increasing and the design life will be dramatically shortened.
Subscription pricing is determined by: 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:. You can adjust all of your cookie settings by navigating the tabs on the left hand side. Reference Radiograph standards E and E provide some overlap of severity levels for similar discontinuity categories within the same energy level range see 4.

ASTM E – 15 Standard Reference Radiographs for Ductile Iron Castings
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. ICS Number Code 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. 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.
Standards Subsctiption may be the perfect solution. Historical Version s – view previous versions of standard. The reference radiograph films are an adjunct to this document and must be purchased separately from ASTM International, if needed see 2.
Categories and severity levels for each discontinuity type represented by these reference radiographs are described in 1. This means that every time you visit this website you will need to enable or disable cookies again.
We have previously been the only manufacturer exclusively supplying tubular anodes to the Durichlor 51 Anode company. 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. At acceptance criteria level 3 the casting may not perform correctly. Strictly Necessary Cookie should be enabled at all times so that we can save your preferences for cookie settings.
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 taking x-ray shots along the length of the casting to ASTM E94 it is possible to view images of the structure. This standard is not e86 in any packages.

A direct comparison of Centrifugally Cast Tubular Anodes and Die Cast Tubular Anodes
The best way to verify the integrity of the sub-surface structure of a casting is by x-ray. Called Type 3 in previous revisions. 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.
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.
