ASTM B955/B955M-07 - 1.10.2007
 
1. Scope

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

1.2 This specification is not intended for aluminum-alloy centrifugal castings used in aerospace applications.

1.3 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 E 527.

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 1 and Annex 2 .

1.6 The values stated in either inch-pound units or SI units are to be regarded separately as standards. The SI units are shown in brackets or in separate tables or columns. The values stated in each system are not exact equivalents; therefore, each system must be used independent of the other. Combining values from the two systems may result in nonconformance with the specification.

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 and health practices and determine the applicability of regulatory limitation prior to use.
