(Specification)Standard Reference Radiographs for Inspection of Aluminum and Magnesium Castings
Standard Reference Radiographs for Inspection of Aluminum and Magnesium Castings
SCOPE
1.1 These reference radiographs illustrate the types and degrees of discontinuities that may be found in aluminum-alloy and magnesium-alloy castings. The castings illustrated are in thicknesses of 1/4 in. [6.35 mm] and 3/4 in. [19.1 mm]. The reference radiograph films are an adjunct to this document and must be purchased separately from ASTM International if needed.
1.2 These film reference radiographs are not intended to illustrate the types and degrees of discontinuities found in aluminum-alloy castings when performing digital radiography. If performing 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 This document may be used where no other applicable document exists, for other material thicknesses for which it has been found to be applicable and for which agreement has been reached between the purchaser and the manufacturer.
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 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.
Note 1—Vol I:The set of reference radiographs consists of 13 plates covering discontinuities in aluminum-alloy castings and 10 plates covering discontinuities in magnesium-alloy castings. Each plate is held in an 81/2 by 11-in. [216 by 279-mm] cardboard frame and each plate 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 of reference radiographs consists of four plates covering discontinuities in magnesium-alloy castings only. Each plate is held in an 81/2 by 11-in. [216 by 279-mm] cardboard frame and illustrates eight grades of severity for the discontinuity (with the exception of discrete discontinuities, where only one example of each discontinuity is given).
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.
