IEC 60310:2016适用于安装在机车车辆上的牵引和辅助电力变压器，以及插入机车车辆牵引和辅助电路中的各种类型的干式或液浸式设计的功率电感器。经买方和制造商同意，本标准也可适用于三相交流线路侧供电车辆的牵引变压器和插入车辆单相或多相辅助电路的变压器，但仪表变压器和额定输出低于1kVA单相或5kVA多相的变压器除外。这个新版本考虑了新的通用铁路标准，更具体地说是参考IEC 62498-1的通用服务条件和参考IEC 61373的冲击和振动考虑。与上一版相比，它还包括以下重大技术变化: -温度限制； -温升试验； -介电测试； -局部放电试验； -电感测量方法； -端子间电压耐受试验等。

IEC 60310:2016 applies to traction and auxiliary power transformers installed on board rolling stock and to the various types of power inductors inserted in the traction and auxiliary circuits of rolling stock, of dry or liquid-immersed design. This standard can also be applied, after agreement between purchaser and manufacturer, to the traction transformers of three-phase AC line-side powered vehicles and to the transformers inserted in the single-phase or poly-phase auxiliary circuits of vehicles, except instrument transformers and transformers of a rated output below 1 kVA single-phase or 5 kVA poly-phase. This new edition takes into account the new generic railway standards, more specifically general service conditions referring to IEC 62498-1 and shock and vibration considerations referring to IEC 61373. It also includes the following significant technical changes with regard to the previous edition:
- temperature limits;
- temperature-rise test;
- dielectric tests;
- partial discharge test;
- inductance measurement methods;
- voltage between terminals withstand test, etc.
