IEC 60317-56:2017规定了180级可焊接全绝缘（FIW）零缺陷漆包圆铜线的要求，该铜线具有基于聚氨酯树脂的单一涂层，如果保留其化学特性并满足所有要求的技术规格，则可以对其进行改性。本标准涵盖的导线的公称导体直径范围如下:FIW等级4、6、8:0,090 mm至0,900 mm。IEC 60317-0-7中规定了标称导体直径。第二版取消并取代了2012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: -第1条:修订范围，将FIW的职系由3至9级减至仅4、6及8级；-条款1:修订范围，将导线直径范围从(0,040至1,600)mm减小至(0,090至0,900)mm； -增加了FIW 3至9级耐磨性要求的信息性附件。

IEC 60317-56:2017 specifies the requirements of solderable fully insulated (FIW) zero-defect enamelled round copper wire, class 180, with a single coating based on polyurethane resin, which may be modified providing it retains its chemical identity and satisfies all the required technical specifications. The range of nominal conductor diameters of the wires covered by this standard is as follows: Grade of FIW 4, 6, 8: 0,090 mm up to and including 0,900 mm. Nominal conductor diameters are specified in IEC 60317-0-7. This second edition cancels and replaces the first edition published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- Clause 1: revision of the scope, reducing the number of grades of FIW from 3 through 9 to 4, 6 and 8 only;
- Clause 1: revision of the scope, reducing the wire diameter range from (0,040 to 1,600) mm to (0,090 to 0,900) mm;
- addition of an informative annex for abrasion resistance requirements for grades FIW 3 to 9.
