线皮限制i问题

IEC60335 表3最后的几句话
j IEC 60245 Types 53 and 57 supply cords have a T rating of 60 °C;
IEC 60245 Type 88 supply cords have a T rating of 70 °C;
IEC 60227 Types 52 and 53 supply cords have a T rating of 70 °C;
IEC 60227 Types 56 and 57 supply cords have a T rating of 90 °C.
在参考前面的 EN标准
Light polyvinyl chloride sheathed flexible cord 60227 IEC 52 H03VV-F
Ordinary polyvinyl chloride sheathed flexible cord 60227 IEC 53 H05VV-F
Heat resistant light polyvinyl chloride sheathed flexible cord 60227 IEC 56 H03V2V2-F
Heat resistant ordinary polyvinyl chloride sheathed flexible cord 60227 IEC 57 H05V2V2-F
Rubber insulated cords
Ordinary tough rubber sheathed flexible cord 60245 IEC 53 H05RR-F
Ordinary polychloroprene sheathed flexible cord 60245 IEC 57 H05RN-F
Cords having high flexibility
Crosslinked PVC insulated and sheathed cord 60245 IEC 88
但是有些线的种类布在这些范围以内想H05VVH2-F的线等等,而且VDE证书里面不写温升限值的,想这类的线是不是按照无T-MARK的线来考虑,也就是说温升限制是50K呢?

可以這樣理解了,標準中無明文規定另外的情形,就依表3中前面所述的要求。
