2、st revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope*1.1 This specification establishes th
3、e requirements for copper-nickel-silicon alloy rod and bar produced from CopperAlloy UNSNo. C64700 in straight lengths.1.2 UnitsThe values stated in either SI units or inch-pound units are to be regarded separately as standard. The values statedin each system may not be exact equivalents; therefore,
4、 each system shall be used independently of the other. Combining valuesfrom the two systems may result in non-conformance with the standard.2.
