电子信息系统机房的磁场干扰环境

Environment of Disturbance from Magnetic Field to Electronic Information System Room

对国家标准《电子信息系统机房设计规范》(GB 50174-2008)有关电子信息系统机房的磁场干扰环境所规定的要求提出质疑。笔者认为,基于磁场的类型和作用时间的长短,设备的抗扰度,实例和试验,文献记载等几点事实,该规范中对磁场干扰强度规定为不大于800 A/m是不合适的,并提出了自己的意见。

Some query about requirement of environment of disturbance from magnetic field in electronic information system room which is coded to state standard （GB 50174 - 2008） Code for design of electronic information system room. is introduced, based on following factors： kind of magnetic field and action time; immunity of equipment; example and experiment; record from literature. It is not suitable to coded magnetic field strength of disturbance to be less than 800 A/m.
