AMS-S-7720B稳定了本文件，因为其他规范中包含了同等的技术要求。AMS-S-7720B已被AMS委员会F宣布为“稳定”，不再接受货币定期审查。用户负责验证参考文件和技术要求的持续适用性。新技术可能存在。AMS F委员会从未对本文件进行过技术更新。如有任何例外情况，用户应向认证机构报告。警告:在许多情况下，买方不是认可的工程组织（即买方可能是次级供应商）。 AMS F委员会建议在未来的采购中使用以下同等技术规范（例如属性、适合性、形式、功能）。本清单不构成用这些规范代替“稳定”规范的权力:ASTM A 276、ASTM A 313/A 313M、ASTM A 314、ASTM A 580/A 580M、AMS 5636、AMS 5637、AMS 5688、AMS 5866、AMS 5690

AMS-S-7720B stabilizes this document because equivalent technical requirements are contained in other specifications.AMS-S-7720B has been declared "STABILIZED" by AMS Committee F and will no longer be subjected to periodic reviews for currency. Users are responsible for verifying references and continued suitability of technical requirements. Newer technology may exist. AMS Committee F has never performed a technical update of this document. Users of this document should refer any certification issues (e.g. exceptions listed on the certification report) to the cognizant engineering organization for their disposition. CAUTION: In many cases the purchaser is not the cognizant engineering organization (i.e. purchaser may be a sub tier supplier). AMS Committee F recommends that the following technically equivalent (e.g. properties, fit, form, function) specification be used for future procurement. This listing does not constitute authority to substitute these specficiations for the "STABILIZED" specification: ASTM A 276, ASTM A 313/A 313M, ASTM A 314, ASTM A 580/A 580M, AMS 5636, AMS 5637, AMS 5688, AMS 5866, AMS 5690
