IEC 60317-51:2014规定了180级可焊接漆包圆铜绕组线的要求，其底涂层基于聚氨酯树脂，只要保留原始树脂的化学特性并满足所有规定的电线要求，就可以对其进行改性。本标准涵盖的公称导体直径范围如下: -1级:0.018 mm至1,000 mm并包括1,000 mm； -2级:0,020毫米至1,000毫米（含1,000毫米）。IEC 60317-0-1:20 13第4条规定了标称导体直径。这第二版取消并取代了2001年出版的第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更: -新的3.2.2载有关于绕组线的一般说明，以前是范围的一部分；-新的3.3包含外观要求； -修订IEC 60317-0-1:20 13的参考文献，以阐明其应用是规范性的； -新订的第23条，针孔测试。 关键词:180级可焊漆包圆铜绕组线聚氨酯树脂

IEC 60317-51:2014 specifies the requirements of solderable enamelled round copper winding wire of class 180 with a sole coating based on polyurethane resin, which may be modified providing it retains the chemical identity of the original resin and meets all specified wire requirements. The range of nominal conductor diameters covered by this standard is as follows:
- Grade 1: 0,018 mm up to and including 1,000 mm;
- Grade 2: 0,020 mm up to and including 1,000 mm. The nominal conductor diameters are specified in Clause 4 of IEC 60317-0-1:2013. This second edition cancels and replaces the first edition published in 2001. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- new 3.2.2 containing general notes on winding wire, formerly a part of the scope;
- new 3.3 containing requirements for appearance;
- revision to references to IEC 60317-0-1:2013 to clarify that their application is normative;
- New Clause 23, Pin hole test. Keywords: solderable enamelled round copper winding wire of class 180, polyurethane resin
