Scope

1.1 These digital reference images illustrate various categories, types, and severity levels of discontinuities that may occur in aluminum-alloy and magnesium-alloy die castings. They are intended to provide:

1.1.1 A guide enabling recognition of discontinuities and their differentiation both as to type and severity level through digital radiographic imaging.

1.1.2 Example digital radiographic illustrations of discontinuities and a nomenclature for reference in acceptance standards, specifications, and drawings.

Note 1: The basis of application for these reference images requires a prior purchaser supplier agreement of radiographic examination attributes and acceptance criteria as described in Sections 5 and 6 of this standard.

1.2 These digital reference images consist of nine images covering discontinuities in aluminum and magnesium alloy die castings. Four contain graded sequences of four levels of increasing severity in aluminum castings. Four contain graded sequences of four levels of increasing severity in magnesium castings. The last image contains ungraded illustrations of inclusions in aluminum and magnesium alloy die castings.

1.3 Two kinds of illustration categories are covered as follows:

1.3.1 Graded—Three discontinuity categories for aluminum die castings and three discontinuity categories for magnesium die castings, each illustrated in four levels of progressively increasing severity. Category A discontinuities are illustrated for aluminum and magnesium die castings having thicknesses of ¹/₈ in. (3.2 mm) and ⁵/₈ in. (15.9 mm); Category B discontinuities are illustrated for ¹/₈ in. thick aluminum and magnesium die castings; and Category C discontinuities are illustrated for ⁵/₈ in. (15.9 mm) thick aluminum and magnesium die castings.

1.3.2 Ungraded—One illustration of one discontinuity for 0.20 in. (5.1 mm) thickness aluminum die casting and one illustration of one discontinuity for ¹/₈ in. (3.2 mm) thickness magnesium die casting.

1.4 This document may be used for other materials, thicknesses or with other energy levels for which it has been found to be applicable and agreement has been reached between purchaser and supplier.

1.5 All areas of this standard may be open to agreement between the cognizant engineering organization and the supplier, or specific direction from the cognizant engineering organization. These items should be addressed in the purchase order or the contract.

1.6 These digital reference images are not ......
