是啊,我说的就是产品工作原理,电路原理!!!
举个例子: 电子镇流器的EN 61347-2-3的: 16 Abnormal conditions
的测试:
Each of the following conditions shall be applied with the ballast operating according to the
manufacturer's instructions (including a heat sink, if specified) for 1 h:
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.
如果对产品原理特性不了解,,试问如何做好这章的安全测试呢??? |
