请教EN 61347-2-3里面16章节中a,b,c,d,e测试条件

如上, 在61347-2-3标准中有以下几个条件:

   a) the lamp or one of the lamps is not inserted;
   b) the lamp does not start because one of the cathodes is broken;
   c) the lamp does not start although the cathode circuits are intact (de-activated lamp);
   d) the lamp operates, but one of the cathodes is de-activated or broken (rectifying effect);
   e) short circuit of the starter switch, if any.

请教下以上a,b,c,d,e中使用的负载情况!

谢谢!!
