Details
1.1 This specification2 establishes requirements for alloys whose copper alloy numbers and compositions are shown in Table 1. The castings may be furnished as one of three types: static chill, centrifugal chill, or sand cast.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 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.
1.4 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.
Rationale:
This specification establishes requirements for gear bronze alloy castings with Copper Alloy No. C90800, C91700, C90700, C91600, and C92900. The castings may be furnished as one of three types: static chill, centrifugal chill, or sand cast. The alloys shall be subject to tensile strength, yield strength, elongation, and Brinell hardness tests. The Brinell readings shall be taken on the grip end of the tension test bar as described in the specification.
