IEC 60317-12:20 20作为IEC 60317-12:20 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 60317-12:20 20规定了120级漆包圆铜绕组线的要求，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指定的电线要求，就可以对其进行修改。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聚乙烯醇缩醛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。本文件涵盖的公称导体直径范围为:-1级:0,040 mm至2,500 mm并包括2,500 mm；-2级:0,040 mm至5,000 mm并包括5,000 mm；-3级:0,080毫米至5,000毫米（含5,000毫米）。IEC 60317-0-1:20 13第4条规定了标称导体直径。IEC 60317-12第四版取消并取代了2010年发布的第三版。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:-范围的修改；-在第20条中增加了对变压器耐油测试方法的引用。

IEC 60317-12:2020 is available as IEC 60317-12:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60317-12:2020 specifies the requirements of enamelled round 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 acetal 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 diameters covered by this document is:
- Grade 1: 0,040 mm up to and including 2,500 mm;
- Grade 2: 0,040 mm up to and including 5,000 mm;
- Grade 3: 0,080 mm up to and including 5,000 mm.
The nominal conductor diameters are specified in Clause 4 of IEC 60317-0-1:2013. This fourth edition of IEC 60317-12 cancels and replaces the third edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- modification of the Scope;
- addition of reference to transformer oil resistance test method in Clause 20.
