IEC 60065 10.1

各位同行们,讨论一下以下试验的试验部位,谢谢大家
10.1 Surge test
The insulation on CLASS II apparatus between ACCESSIBLE parts or parts connected to them and
HAZARDOUS LIVE parts, shall withstand surges due to transients, caused for example by
thunderstorms and entering the apparatus through the antenna TERMINAL.
Compliance is checked by the following test:
The insulation between
– TERMINALS for the connection of antenna and MAINS supply TERMINALS,
and between
– MAINS supply TERMINALS and any other TERMINAL in case of apparatus providing supply
voltages to other apparatus with antenna TERMINALS,
is subjected to 50 discharges at a maximum rate of 12/min, from a 1 nF capacitor charged to
10 kV in a test circuit, as shown in Figure 5a.
NOTE During this test, the apparatus should not be energized.
After the test, the tested insulation shall comply with the requirements of 10.3.

个人理解:这个标准条款讲的是电涌试验(模拟雷击),以电视机举例,一般是高频头(TV端子),像中国90年代的时候,电视机自己在外面引天线,然后接到TV端子,搜索电视机信号,在雷雨天气,有可能通过TV端子,电视机遭到雷击;现在条件好一点了,还是通过天线端子转接,再连接机顶盒。不清楚外国的天线端子是咋样接到自己家的音视频设备上的。请指教!

哦哦,是的!
可是,进行电涌测试时,测试部位是?
