IEC 60317-72:2020作为IEC 60317-72:2020 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 60317-72:2020规定了聚酯玻璃纤维缠绕硅树脂/清漆浸渍的裸1级或2级漆包圆铜绕组线的要求，温度指数200。注意:对于这种类型的导线，热冲击试验是不合适的，因此无法确定热冲击温度。因此，不能指定基于温度指数和热冲击温度要求的等级。IEC 60317-0-10:20 17第4条规定了标称导体直径。这第二版取消并取代了2017年出版的第一版。作为修正案1分发给各国家委员会的第55/1768/CDV号文件促成了这一新版本的出版。与上一版相比，此版本包括以下重大技术变更: -标题的修改； -修订范围； -修订至3.2.2。

IEC 60317-72:2020 is available as IEC 60317-72:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60317-72: 2020 specifies the requirements of polyester glass-fibre wound silicone resin/varnish impregnated, bare, grade 1 or grade 2 enamelled round copper winding wire, temperature index 200. NOTE For this type of wire, the heat shock test is inappropriate and therefore a heat shock temperature cannot be established. Consequently, a class based on the requirements for temperature index and heat shock temperature cannot be specified. The nominal conductor diameters are specified in IEC 60317-0-10:2017, Clause 4. This second edition cancels and replaces the first edition published in 2017. The document 55/1768/CDV, circulated to the National Committees as Amendment 1, led to the publication of this new edition. This edition includes the following significant technical changes with respect to the previous edition:
- modification of the title;
- revision to the Scope;
- revision to 3.2.2.
