IEC 60317的本部分规定了155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，可对其进行修改，前提是其保留原树脂的化学特性，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。交叉引用:IEC 60317-0-1:2013EN 60317-0-1:2014IEC 60264IEC 60317IEC 60851包含以下内容:修订，2019年10月

This part of IEC 60317 specifies the requirements of solderable enamelled round copper winding wire of class 155 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.Cross References:IEC 60317-0-1:2013EN 60317-0-1:2014IEC 60264IEC 60317IEC 60851Incorporates the following:Amendment, October 2019
