| 摘 要： | 国标GB8898—2011新版本对条款内容进行了删减和修改，影响较大的内容包括海拔高度增加至5000米电气间隙限值的颠覆性修改、增加热带气候条件下温升、潮热、接触电流限值的调整、距潜在引燃源距离所要求的绝缘材料的防火等级、补充对元器件如压敏电阻、PTC热敏电阻、光电耦合器的测试条款等。该文将对标准进行解读并探讨相关产品在今后设计方面应注意的环节。

| Abstract: | Modifications have been implemented from standard GB8898-2011,including values of clear- ance for altitude 5 000 meters area at which apparatus intended to be used,and values of heating,hu- midity treatment,touch current of which the topic area of apparatus intended to be used at.The require- ment of flammability category of components and parts were different from previous standard,compo- nents such as PTC thermistors,surge suppression varistors and optocoupler need to be tested by new requirement.This article will Interpret requirements of standard and make some suggestions for product design. |
