UL8750 条款解读

各位大侠，请帮忙解读一下 下面豁免条款，有点看不懂

Exception No. 1: Spacings between uninsulated live parts of different voltage on non-conformal coated
printed wiring boards, their connectors, and board-mounted electrical components wired on the load side
of line filters or similar voltage peak reduction networks and components, are permitted to be 0.58 mm
(0.0230 in) plus 0.005 mm (0.0002 in) per V peak

我没做过8750的标准, 我理解的意思大概是讲:在滤波器或类似的可以抑制网络峰值电压的零件之后的非绝缘的相反极性带电部件之间的spacing为0.58mm + 0.005 * Vpeak，诸如连接端子的脚位，board-mounted的零部件的两极。

一般通过裸板耐压来解决了
