请教一个60065 11.2.3的问题
EN60065 2002版本 有三个条件1.5mins max& 210K
2. 符合20.1.3要求
a.<2 cm2PCB(不明白这个2cm2 PCB指的是什么面积？是PCB的大小，还是故障时燃烧的面积不要超过2cm2），不要超过210K
b。。。。
很繁琐。。。。
但是最新版本IEC 60065 2011版本的说的很清楚
11.2.3 Parts, other than windings and PRINTED BOARDS, providing electrical insulation
The temperature rise of insulating parts other than windings and PRINTED BOARDS, the failure of
which would cause an infringement of the requirements of 11.1, 11.2.2 and 11.2.4, shall not
exceed the values given in Table 3, item b) "Fault conditions".
If a temperature rise limit is exceeded, and if there is doubt as to whether or not an electric
shock hazard exists, a short circuit is applied between the conductive parts concerned and the
tests of 11.1 are repeated.
最新的就说的很清楚。 是指故障时燃烧的面积不要超过2cm2.
现在基本都是申请新版了，因此应当不存在旧版的问题. 谢谢！！
