ASTM E ASTM D ASTM E A number in parentheses indicates the year of last reapproval. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Scope 1. They are intended to provide: 1. NOTE 1—The set of reference radiographs consists of? The 5 frames are contained in a ? NOTE 2—Reference radiographs applicable to aluminum and magnesium castings up to 2 in.
Category A discontinuities are illustrated for aluminum and magnesium die castings having thicknesses of 1? 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.
Referenced Documents 2. Terminology 3. Appearance of Radiographic Indications 4. These descriptions apply to these reference radiographs only. Current edition approved Dec. Published January Originally approved in Last previous edition approved in as E - Order RRE They may indicate the inclusion of oxide or dross or metallic compounds of different density. Illustration shows a more dense material. The radiographs are of castings that were produced under conditions designed to produce the discontinuities.
These reference radiographs are intended to be used for casting thickness ranges in accordance with Table 1. Two ungraded illustrations have been included to establish the radiographic appearance of foreign material.
All of the references are original radiographs. The extent to which the image deteriorates over time is a function of storage conditions, care in handling and amount of use.
Reference radiograph? The radiographs should therefore be periodically examined for signs of wear and tear, including scratches, abrasions, stains, and so forth. Any reference radiographs which show signs of excessive wear and tear which could in?
Basis for Application 6. Appli- cation of these reference radiographs as acceptance standards should be based on the intended use of the product and the following considerations see Note 3 : 6. The size of the unit area should be speci? Discontinuities more severe than those in the speci? Different grades or acceptance limits may be speci? Further, different grades may be speci?
Any modi? NOTE 3—Caution should be exercised in specifying the acceptance criteria to be met in the casting. Casting design coupled with foundry practice should be considered. It is advisable to consult with the manufacturer or foundry before establishing the acceptance criteria to ensure the desired quality level can be achieved.

Standard Reference Radiographs for Inspection of Aluminum and Magnesium Die Castings
If you like to setup a quick demo, let us know at support madcad. These radiographs are so designed that acceptance standards, which may be developed for particular requirements, can be specified in terms of these radiographs. The radiographs are of castings that were produced under conditions designed to produce the discontinuities. These reference radiographs are intended to be used for casting thickness ranges in accordance with Table 1. The radiographic illustrations listed in Table 1 illustrate three types of discontinuities in four severity levels.
