UL 1310 开关电源初级零件与次级零件间距离？

UL 1310 开关电源初级零件与次级零件间距离？
标准只看到 不同极性间（L/N,fuse 两端），导电部件与非导电金属部件有空气间歇和爬电距离，但初级零件铜箔到次级零件铜箔有距离要求吗？似乎标准中没找到，烦请高手说下？
Spacings between live parts of opposite polarity, between live and dead metal parts, and betweenlive parts and a metal enclosure, shall be as specified in Table 24.1 or Table 24.2, as appropriate. If a livepart is not rigidly secured in position by a means other than friction between surfaces, or if a movable deadmetal part is in proximity to an uninsulated live part, the construction shall be such that at least theminimum spacings will be maintained.

开关电源初级零件与次级零件 需要满足 UL62368 或者UL60950的加强绝缘要求即可。

这里说的是UL 1310呀

初次级按照between live and dead metal parts来看
