1.1 本规范涵盖了由牛皮纸、棉花或牛皮纸和棉浆制成的用于电气绝缘的纸板。该电路板用于变压器和其他电气设备中的电介质或结构用途。 1.2 电绝缘板最常被称为（在本文中也将被称为）纸板。用于纸板的其他术语包括变压器板、富勒板和压锅。 1.3 本规范涵盖标称厚度为0.030至0.315英寸的纸板。（0.8至8.0 mm）。对于较薄的材料，请参阅规范 D1305 . 1.4 可用的最大厚度将因类型和制造商而异。最大板材尺寸将因厚度、类型和制造商而异。 1.5 纸板通常应湿铺而不粘贴。除非买方另有规定，否则本规范不包括由两张或多张用粘合剂层压在一起的纸板。 注1: 本规范中描述的材料类似于IEC规范641-3第1页B.0.1、B.2.1、B.2.3、B.3.1和B.3.3中描述的相应类型的纸板。 1.6 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.7 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 pressboard for electrical insulating purposes, manufactured from kraft, cotton, or kraft and cotton pulps. This board is intended for dielectrical or structural purposes in transformers and other electrical apparatus. 1.2 Electrical insulating boards are most commonly referred to (and will be referred to herein) as pressboard. Other terms used for pressboard include transformer board, fuller board, and presspan. 1.3 This specification covers pressboard having a nominal thickness of 0.030 to 0.315 in. (0.8 to 8.0 mm). For thinner material refer to Specification D1305 . 1.4 The maximum thickness available will differ with the type and the manufacturer. The maximum sheet size will differ with the thickness, type, and manufacturer. 1.5 Pressboard shall normally be plied wet without pasting. Unless specified by the purchaser, this specification does not include pressboard comprised of two or more sheets that have been laminated together using an adhesive. Note 1: The materials described in this specification are similar to corresponding types of pressboard described in IEC Specification 641-3, Sheet 1, Types B.0.1, B.2.1, B.2.3, B.3.1, and B.3.3. 1.6 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.7 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.
