ASTM WK45901

    New Practice for Digital Reference Images for Aluminum and Magnesium Die Castings

    (What is a Work Item?)

    Developed by Subcommittee: E07.02 | Committee E07 | Contact Staff Manager


    1. Scope

    1. Scope 1.1 These digital reference images illustrate the 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 thier differentiation bot as to type and severity level through digital X-ray examination. 1.1.2 Example digital X-ray illustrations of discontinuities and a nomenclature for reference in acceptance standards, specifications, and drawings. 1.1.3 The values stated in inch-pound units are to be regarded as standard. Teh values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.2 Two kinds of illustration categores are covered as follows: 1.2.1 Graded -- Three discontinuity categories for aluminum die castings and three discontinuity categories for magnesium die castings, each illustrted in four levels of progressively increasing severity. Category A discontinuities are illustrated for aluminum and magnesium die castings have thicknesses of 1/8 in. (3.2 mm) and 5/8 in. (15.9 mm); Category B discontinuities are illustrated for 1/8 in. (3.2 mm) thick aluminum and magnesium die castings; and Category C discontinuities are illustrated for 5/8 in. thick (15.9 mm) thick aluminum and magnesium die castings. 1.2.2 Ungraded -- One illustration of one discontinuity for 0.2 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.

    The existing ASTM E505 reference radiographs are applicable for film radiography. New digital reference images are needed for use with digital X-ray imaging systems.
