1.1 本规范涵盖了规定磁性应用扁钢采购和交付要求的一般程序。当不存在适用的单独规范时，本规范允许用户通过在采购订单上指定某些要求并引用本规范，在磁质量、取样、测试、包装等受控条件下订购合适的材料。 1.2 符合本规范的单个ASTM电工钢规范为规范 A677型 , A683型 , A726 , A840 , A876 和 A1086号 . 注1: 有关与本规范相关的其他标准的更多信息，请参阅以下内容:测试方法 A341/A341M , A343/A343M , A348/A348M , A596/A596M , A712 , A717/A717M , A719/A719M , A720/A720M , A721/A721M , A773/A773M , A804/A804M , A889/A889M , A937/A937M , A971/A971M ，并练习 A664型 . 1.3 以国际单位制表示的数值应视为标准值。括号中给出的数值是到常用（cgs-emu和inch-pound）单位的数学转换，仅供参考，不被视为标准。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 This specification covers general procedures for specifying requirements in the procurement and delivery of flat-rolled electrical steels for magnetic applications. When an applicable individual specification does not exist, this specification enables the user to order a suitable material to be supplied under controlled conditions with respect to magnetic quality, sampling, testing, packaging, and so forth, by specifying certain requirements on the purchase order and citing this specification. 1.2 Individual ASTM electrical steel specifications that are in conformity with this specification are Specifications A677 , A683 , A726 , A840 , A876 , and A1086 . Note 1: For more information on other standards associated with this specification, refer to the following: Test Methods A341/A341M , A343/A343M , A348/A348M , A596/A596M , A712 , A717/A717M , A719/A719M , A720/A720M , A721/A721M , A773/A773M , A804/A804M , A889/A889M , A937/A937M , A971/A971M , and Practice A664 . 1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to customary (cgs-emu and inch-pound) units which are provided for information only and are not considered standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
