ASTM E155-14

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 and magnesium-alloy castings when performing digital radiography. If performing digital radiography of aluminum-alloy castings, refer to Digital Reference Image Standard E2422. If performing digital radiography of magnesium-alloy castings, refer to Digital Reference Image Standard E2869.

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. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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.
