产品申请IEC/ EN 62368-1认证, 如果变压器（ transformer）耐热性分级高于105（A）级时，变压器绝缘系统（EIS）应该满足IEC 60085.的要求，标准如下：

For thermal classifications above Class 105, the E/S shall comply with IEC 60085

市场上符合IEC 60085的绝缘系统文件很少，那么常见的UL认可的“EIS”(UL 1446)是否可以接受呢？

答案是可以的，依据如下决议：

If a Electrical Insulation Systems needs temperature limit higher than Class 105 (Class A), IEC 62368-1:2014 and 2017 requires an insulation system (EIS) in accordance with IEC 60085.

As there is a limited number of Electrical Insulation Systems that are documented in accordance with IEC 60085, could UL recognized Electrical Insulation Systems (in accordance with UL 1446) be accepted until there is a sufficient database for systems that comply with EC 60085?

Decision

Electrical Insulation Systems recognized in accordance with UL 1446 are also accepted..

Explanatory notes

There are no significant differences between IEC 60085 and UL 1446 that would imply any safety risk in end products according to IEC 62368-1.

EIS categories OBJS2/OBJY2 (UL 1446) and ODCA2/OCTU2 (IEC 60085) are listed at the UL website.
