1.1 本文件根据成分、相对绝缘能力和功能性对电工钢的绝缘涂层进行分类。该分类的目的是通过提供有关涂层化学性质和用途的一般信息来帮助绝缘涂层的用户，并提供有关其使用限制的重要数据，即相对绝缘能力、可冲压性、温度稳定性、焊接性和可制造性。每种涂层的比表面绝缘电阻率值不包括在本分类中。用户请参阅 1.2 是否需要有关表面绝缘电阻率值的更详细信息。 1.2 该分类将与公寓的各种规格一起使用- A06委员会管辖下的轧制电工钢，包括规范 A345型 , A677型 , A683型 , A726 , A840 , A876 和 A1086号 . 但是，在此类情况下，如果涂层描述和特性在本分类和任何规范之间存在差异，则本分类应取代本规范。 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。 ====意义和用途====== 4.1 该分类根据其化学性质、相对绝缘能力和典型应用确定了绝缘涂层的类别。这些类别描述了涂层的一般物理和化学特性，这些特性有助于广泛估计其绝缘能力和适用于各种应用。

1.1 This document classifies insulating coatings for electrical steels according to their composition, relative insulating ability, and functionality. The purpose of this classification is to assist users of insulating coatings by providing general information about the chemical nature and use of the coatings, as well as to provide important data concerning limits to their use, that is, relative insulating ability, punchability, temperature stability, weldability, and fabricability. Specific surface insulation resistivity values for each coating are not included in this classification. The user is referred to the flat-rolled electrical steel specifications noted in 1.2 should more detailed information concerning surface insulation resistivity values be required. 1.2 This classification is to be used in conjunction with the various specifications for flat-rolled electrical steels under the jurisdiction of Committee A06, including Specifications A345 , A677 , A683 , A726 , A840 , A876 , and A1086 . However, in those instances in which the coating descriptions and characteristics differ between this classification and any of the specifications, this classification shall supersede the specification. 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. ====== Significance And Use ====== 4.1 This classification establishes categories of insulating coatings based on their chemical nature, relative insulating ability, and typical applications. These categories describe general physical and chemical characteristics of the coatings that are useful in making broad estimates of their insulating ability and suitability for various applications.
