1.1 本规范涵盖了平轧无取向全加工电工钢应符合的详细要求。 1.2 这种钢是按照规定的最大芯损耗值生产的，主要用于商用电源频率（50 Hz和60Hz）在磁性器件中的应用。在轧机加工过程中产生了理想的芯损耗和磁导率特性，因此通常不需要用户进行额外的热处理。 1.3 这些未取向的完全加工的电工钢是低碳的、含硅的铁或硅铝铁合金，其含量高达约3.5 % 硅和少量铝。 1.4 以国际单位制表示的数值应视为标准。括号中给出的值是对习惯（cgs-emu和inch）的数学转换- 磅）单位，这些单位仅供参考，不被视为标准单位。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

1.1 This specification covers the detailed requirements to which flat-rolled nonoriented fully processed electrical steel shall conform. 1.2 This steel is produced to specified maximum core-loss values and is intended primarily for commercial power frequency (50 Hz and 60 Hz) applications in magnetic devices. Desirable core-loss and permeability characteristics are developed during mill processing, so additional heat treatment by the user is usually not necessary. 1.3 These nonoriented fully processed electrical steels are low-carbon, silicon-iron, or silicon-aluminum-iron alloys containing up to about 3.5 % silicon and a small amount of aluminum. 1.4 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. 1.5 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.
