IEC 60317-2:20 19作为IEC 60317-2:20 19 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 60317-2:20 19规定了130级双涂层可焊漆包圆铜绕组线的要求。底层涂层基于聚氨酯树脂，只要其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。叠加涂层是基于热塑性树脂的粘合层。注改性树脂是经过化学变化的树脂，或含有一种或多种添加剂以增强某些性能或应用特性的树脂。本标准涵盖的公称导体直径范围为:-1B级:0,020 mm至2,000 mm并包括2,000 mm； -2B级:0,020毫米至2,000毫米（含2,000毫米）。 IEC 60317-0-1:20 13第4条规定了标称导体直径。这第五版取消并取代了2012年出版的第四版。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: a)增加标称导体直径为0.050 mm(包括0.050 mm)的热粘合试验载荷； b)根据IEC 60317-0-1:20 13增加针孔测试要求。 关键词:绕组用绝缘导线

IEC 60317-2:2019 is available as IEC 60317-2:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60317-2:2019 specifies the requirements of solderable enamelled round copper winding wire of class 130 with a dual coating. The underlying coating is 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 superimposed coating is a bonding layer based on a thermoplastic resin. NOTE A modified resin is a resin that has undergone a chemical change, or contains one or more additives to enhance certain performance or application characteristics. The range of nominal conductor diameters covered by this standard is:
– Grade 1B: 0,020 mm up to and including 2,000 mm;
– Grade 2B: 0,020 mm up to and including 2,000 mm.
The nominal conductor diameters are specified in Clause 4 of IEC 60317-0-1:2013. This fifth edition cancels and replaces the fourth edition published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) addition of heat bonding test loads for nominal conductor diameters up to and including 0,050 mm;
b) addition of pin hole test requirements according to IEC 60317-0-1:2013.
