BS EN 50664:2017的目的是提供一种评估工人使用的设备的方法 人体暴露于电场、磁场和电磁场、感应电流和接触电流的限制 在其运行环境中投入使用时，以及在现场或上市后评估 这样的设备。覆盖的频率范围为0 Hz至300 GHz。本标准不适用于现场使用的协调设备 有关于工人暴露于电磁场的标准。如果确实存在这样的标准，那么 应该使用。在撰写本文时，有一个适用于基站设备的标准 应用于将此类设备投入使用或对工人进行现场评估 电磁场暴露:EN 50401:2017。证明基站设备符合以下要求的产品标准: 射频电磁场暴露限值（110 MHz-100 GHz），当投入使用时，应在使用本指令时参考各指令下协调的现行标准清单 标准交叉引用:EN 62311（IEC 62311:2007Mod）ASEN 50499:2008IEC 62311:2007购买时可用的所有当前修订版均包含在本文件的购买中。

The object of BS EN 50664:2017 is to provide a route for evaluation of equipment used by workers against limits on human exposure to electric, magnetic and electromagnetic fields, and induced and contact current when it is put into service in its operational environment, and also for in situ or post-market evaluation of such equipment.The frequency range covered is 0 Hz to 300 GHz.This standard applies to equipment for which no dedicated harmonized putting-into-service or in situ product standard regarding worker exposure to electromagnetic fields exists. If such a standard does exist then it should be used. At the time of writing there is one applicable standard, for base station equipment, and this should be used for putting-into service or in situ assessment of such equipment with respect to worker exposure to electromagnetic fields:EN 50401:2017. Product standard to demonstrate the compliance of base station equipment with radiofrequency electromagnetic field exposure limits (110 MHz - 100 GHz), when put into serviceThe current list of standards harmonized under each Directive should be consulted at the time of use of this standard.Cross References:EN 62311(IEC 62311:2007Mod) ASEN 50499:2008IEC 62311:2007All current amendments available at time of purchase are included with the purchase of this document.
