标题: EN 62115 2011的14.15问题 [打印本页] 作者: 荷花 时间: 2011-8-24 21:10 标题: EN 62115 2011的14.15问题 EN 62115 2011 14.15里提到当玩具在额定电压下供电时，玩具的任何两个部位间的工作电压不得超过5KV。。。。
这个5KV有可能超过吗？？为什么设定得那么高？？用什么仪器来测呢？？欢迎大家讨论，谢谢
原文如下
14.15 Internal parts of a toy having a voltage exceeding 24 V shall not lead to any risk of
harmful electric shock.
Compliance is checked by inspection and measurement. Protective parts or parts preventing
access to live parts are removed, even if the toy has to be damaged.
The quantity of electricity and energy in the discharge is measured using a resistor having a
nominal non-inductive resistance of 100 . The current is measured using the circuit in
Figure 4 of IEC 60990. In all conditions of test, the following values shall be met:
– the working voltage between any two parts of the toy shall not exceed 5 KV when the
toy is supplied at rated voltage;
– the maximum current from a circuit with a generated voltage exceeding 24 V shall be less
than 0,5 mA;
– the maximum energy from a circuit with a generated voltage exceeding 24 V shall be less
than 2 mJ;
– the discharge shall not exceed 45 µC.作者: 老李 时间: 2011-8-24 21:10
应该要用静电式电压表作者: 荷花 时间: 2011-8-24 21:10
谢谢，我在想为什么要设成5KV那么高呢？？会有可能达到这个数值吗？？作者: 阿细 时间: 2011-8-24 21:10
那可能是为了实现一些神奇有趣的功能吧，所有标准都会受一些超级集团利益所左右，只要能认实其没有危险，各方就会接受。
