标准摘要
[中文适用范围]： 本部分 IEC 60317 规定了具有双重涂层的130级可焊性漆包圆铜绕组线的要求。底层涂层基于聚氨酯树脂，可以改性，只要它保留原始树脂的化学特性并满足所有规定的电线要求。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，或含有一个或多个添加剂以增强某些性能或应用特性。 本标准涵盖的标称导体直径范围为： Grade1B: 0.020 mm 至 2.000 mm（含） Grade2B: 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 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its 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. Keywords: insulated wires used for windings
