A number in parentheses indicates the year of last reapproval.A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This specification establishes the requirement
3、s forcopper-nickel-silicon alloy rod and bar produced from CopperAlloy UNS No. C64700 in straight lengths.1.2 UnitsThe values stated in either inch-pound or in SIunits are to be regarded separately as standard. Within the text,the SI units are shown in brackets. The values stated in eachsystem may n
4、ot be exact equivalents; therefore, each systemshall be used independently of the other. Combining valuesfrom the two systems may result in nonconformance with thestandard.2.
