自2008年1月起，本规范已被SAE航空材料部宣布“取消”，并被SAE AMS 2224取代。每当提及已取消的MAM 2224C时，应满足最新版AMS 2224的要求。通过这一行动，本文件仍将列在航空航天材料规范索引的数字部分，并指出其已被SAE AMS 2224取代。本规范涵盖了适用于订购公制（SI）尺寸的铜和铜合金线的既定公制制造公差。除非另有说明，否则这些公差适用于所有条件。AMS 2224是该MAM的英寸/磅版本。

This specification has been declared “CANCELLED” by the Aerospace Materials Division, SAE, as of January 2008 and has been superseded by SAE AMS 2224. The requirements of the latest issue of AMS 2224 shall be fulfilled whenever reference is made to the cancelled MAM 2224C. By this action, this document will remain listed in the Numerical Section of the Index of Aerospace Material Specifications, noting that it has been superseded by SAE AMS 2224.This specification covers established metric manufacturing tolerances applicable to copper and copper alloy wire ordered to metric (SI) dimensions. These tolerances apply to all conditions, unless otherwise noted. AMS 2224 is the inch/pound version of this MAM.
