Standard Reference Radiographs for Inspection of Aluminum and Magnesium Die Castings

Importancia y uso:

5.1 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.

5.2 The radiographic illustrations listed in Table 1 illustrate three types of discontinuities in four severity levels. Two ungraded illustrations have been included to establish the radiographic appearance of foreign material.

5.3 These reference radiographs were produced in accordance with Guide E94. All of the references are original radiographs.

5.4 Film Deterioration—Radiographic films are subject to wear and tear from handling and use. The extent to which the image deteriorates over time is a function of storage conditions, care in handling and amount of use. Reference radiograph films are no exception and may exhibit a loss in image quality over time. 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 influence the interpretation and use of the radiographs should be replaced.
