1.1 These reference radiographs illustrate the types and degrees of discontinuities that may be found inaluminum-alloy and magnesium-alloy castings. The castings illustrated are in thicknesses of 1/4 in. [6.35 mm] and3/4 in. [19.1 mm]. The reference radiograph films are an adjunct to this document and must be purchased separatelyfrom ASTM International if needed.
1.2 These film reference radiographs are not intended to illustrate thetypes and degrees of discontinuities found in aluminum-alloy castings when performing digital radiography. Ifperforming digital radiography of aluminum-alloy castings, refer to Digital Refererence Image Standard E 2422.Magnesium-alloy digital reference images are not currently available from ASTM International.
1.3 Thisdocument may be used where no other applicable document exists, for other material thicknesses for which it hasbeen found to be applicable and for which agreement has been reached between the purchaser and themanufacturer.
1.4 The values stated in inch-pound units are to be regarded as the standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appropriate safety and health practices and determine theapplicability of regulatory limitations prior to use.
Note 1 – Vol I:The set of reference radiographsconsists of 13 plates covering discontinuities in aluminum-alloy castings and 10 plates covering discontinuitiesin magnesium-alloy castings. Each plate is held in an 81/2 by 11-in. [216 by 279-mm] cardboard frame and eachplate illustrates eight grades of severity for the discontinuity in approximately a 2 by 2-in. [51 by 51-mm] area.The cardboard frames are contained in a 101/2 by 111/2-in. [267 by 292-mm] ring binder.
Vol. II: The set ofreference radiographs consists of four plates covering discontinuities in magnesium-alloy castings only. Eachplate is held in an 81/2 by 11-in. [216 by 279-mm] cardboard frame and illustrates eight grades of severity forthe discontinuity (with the exception of discrete discontinuities, where only one example of each discontinuity isgiven).
Note 2 – Reference radiographs applicable to aluminum and magnesium die castings up to 1 in. [25 mm]in thickness are contained in Reference Radiographs E 505.
