This specification covers aluminum-alloy permanent mold castings. The responsibility of furnishing castings that can be laid out and machined to the finished dimensions within the permissible variations specified shall rest with the producer, except where mold equipment is furnished by the purchaser. Samples for chemical analysis shall be taken by sawing, drilling, or milling the casting or test specimens in such a manner as to be representative of the material. Unless otherwise specified, only aluminum or producers foundry scrap shall be used in the re-melting furnace from which molten metal is taken for pouring directly into castings. Pure materials, recycled materials, and master alloys may be used to make alloys conforming to this specification. Foundry control shall consist of examination of castings by radiographic or other approved methods for determining internal discontinuities until the gating, pouring, and other foundry practices have been established to produce castings meeting the quality standards furnished by the purchaser or agreed upon by the purchaser and the producer. Separately cast test specimens shall be cast in iron molds. If the castings are to be heat treated and separately cast specimens are to be used, the specimens representing such castings shall be heat treated with the castings they represent. If castings are to be heat treated and tests are to be obtained on the castings, the test specimens shall be taken from the castings after heat treatment. One per melt-heat combination shall be tested when tensile properties of castings are to be determined. The finished castings shall be uniform in composition and free of blowholes, cracks, shrinks, and other discontinuities.

the full text of the standard itself must be referred to for its use and application.
ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
 This specification covers aluminum-alloy permanent mold castings designated as shown in Table 1.
 This specification is for aluminum-alloy permanent mold castings used in general purpose applications. It may not address the mechanical properties, integrity testing, and verification required for highly loaded or safety critical applications.
 Alloy and temper designations are in accordance with ANSI H35.1/H35.1(M). The equivalent unified numbering system alloy designations are in accordance with Practice E527.
 Unless the order specifies the “M” specification designation, the material shall be furnished to the inch-pound units.
 For acceptance criteria for inclusion of new aluminum and aluminum alloys and their properties in this specification, see Annex A1 and Annex A2.
 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not
therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
 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.
