IEC 60317-18:20 20作为IEC 60317-18:20 20 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 60317-18:20 20规定了要求120级漆包矩形铜绕组线，其底涂层基于聚乙烯醇缩醛或聚乙烯醇缩甲醛树脂，只要保留原始树脂的化学特性并满足所有规定的电线要求，即可对其进行修改 注1改性树脂是指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。 注2聚乙酸乙烯酯是通过聚乙烯醇与醛缩合生产的热塑性乙烯基树脂家族的总称。实例是聚乙烯醇缩醛、聚乙烯醇缩甲醛和聚乙烯醇缩丁醛。 本文件涵盖的标称导体尺寸范围为: -宽度:最小。2.0 mm最大31.5 mm； -厚度:最小。最大0.80毫米。10.0毫米。 本规范包括1级和2级导线，适用于所有导线。IEC 60317-0-2中给出了宽度和厚度的规定组合以及规定的宽度/厚度比。这第四版取消并取代了2004年出版的第三版和修正案1:20 09。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: -修改范围(条款1)； -将3.2.2中的热等级名称从105修订为120； -将拉伸试验更名为粘附试验，并修改8.2中的要求； -修订第10条中的直通要求。

IEC 60317-18:2020 is available as IEC 60317-18:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60317-18:2020 specifies the requirements of enamelled rectangular copper winding wires of class 120 with a sole coating based on polyvinyl acetal or polyvinyl formal resin, which can be modified provided it retains the chemical identity of the original resin and meets all specified wire requirements
NOTE 1 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.
NOTE 2 Polyvinyl acetate is a general name for a family of thermoplastic vinyl resins produced by the condensation of polyvinyl alcohol with an aldehyde. Examples are polyvinyl acetal, polyvinyl formal and polyvinyl butyral.
The range of nominal conductor dimensions covered by this document is:
- width: min. 2,0 mm max. 31,5 mm;
- thickness: min. 0,80 mm max. 10,0 mm.
Wires of grade 1 and grade 2 are included in this specification and apply to the complete range of conductors. The specified combinations of width and thickness as well as the specified ratio width/thickness are given in IEC 60317-0-2. This fourth edition cancels and replaces the third edition published in 2004 and Amendment 1:2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- modification of the Scope (Clause 1);
- revision to thermal class designation from 105 to 120 in 3.2.2;
- renaming of stretching test to adherence test, and modification to the requirements in 8.2;
- revision to the cut-through requirement in Clause 10.
