标准摘要
[中文适用范围]： 本部分IEC 60317规定了130级可焊性双涂层漆包圆铜绕组线的要求。底层涂层基于聚氨酯树脂，可以进行改性，只要它保留原始树脂的化学特性并满足所有规定的线材要求。叠加涂层是基于热塑性树脂的粘合层。 注：改性树脂是指经过化学变化或含有一个或多个添加剂以增强某些性能或应用特性的树脂。 本标准涵盖的标称导体直径范围为： 1B级：0.020 mm至2.000 mm（含） 2B级：0.020 mm至2.000 mm（含） 标称导体直径在IEC 60317-0-1:2013的第4条中规定。 [外文原描述]： 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. Keywords: insulated wires used for windings
