Annotation of standard text ASTM B618/B618M-18e1 :
This specification covers aluminum-alloy investment castings. Unless otherwise specified, only aluminum alloy conforming to the requirements shall be used in the remelting furnace from which molten metal is taken for pouring directly into castings. The castings shall conform to the chemical composition requirements specified. The determination of chemical composition shall be made in accordance with suitable chemical (test methods E 34), or spectrochemical (test methods E 607 and E 1251) methods. Unless otherwise specified, only aluminum alloy conforming to the requirements shall be used in the remelting furnace from which molten metal is taken for pouring directly into castings. 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 required quality standards. The tensile properties shall be determined in accordance with test methods B 557 and B 557M. Heat treatment of castings shall be performed in accordance with practice B 917/B 917M.

1.1 This specification covers aluminum-alloy investment castings designated as shown in Table 1. 1.2 This specification is for
aluminum-alloy investment 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.
1.3 Alloy and temper designations are in accordance with ANSI H35.1/H35.1 (M). 1.4 Unless the order specifies the “M” specification designation, the material shall be furnished to the inch-pound units. 1.5 For acceptance criteria for inclusion of new aluminum and aluminum alloys and their properties in this specification, see Annex A1 and Annex A2. 1.6 Units—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 be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 1.7 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
