Anotace textu normy ASTM B955/B955M-18 :

This specification covers the standard for aluminum-alloy centrifugal castings. This specification does not cover aluminum-alloy centrifugal castings used in aerospace applications. The castings shall be in accordance to the prescribed chemical composition. Chemical composition shall be determined by analyzing samples at the time the castings are poured, or samples taken from castings or tension test specimens. Unless otherwise stated, the tensile strength, yield strength and elongation of test specimens cut from casting shall be in accordance with the standards prescribed herein. If the specimens fail to conform to tension requirements, test bars representative of the castings may be retested in accordance with the replacement tests and retest provisions.

1. Scope

1.1 This specification covers aluminum-alloy centrifugal castings designated as shown in Table 1.

1.2 This specification is for aluminum-alloy centrifugal 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 non-conformance 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.
