自2009年3月起，该规范已被SAE航空航天材料部宣布“取消”，并被AMS4316取代。每当参考已取消的AMS-QQ-A-250/25时，应满足AMS4316最新版本的要求。通过这一行动，本文件将保留在航空航天材料规范索引的数字部分，并注意到它已被AMS4316取代。 取消的质量标准可从SAE获得。

This specification has been declared "CANCELLED " by the Aerospace Materials Division, SAE, as of March 2009 and has been superseded by AMS4316. The requirements of the latest issue of AMS4316 shall be fulfilled whenever reference is made to the cancelled AMS-QQ-A-250/25. 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will remain listed in the Numerical Section of the Index of Aerospace Material Specifications, noting that it has been superseded by AMS4316. Cancelled specifications are available from SAE.
