无线充电器的标准可以是part 15 或 part 18，取决于充电设备和接受充电的设备之间是否有通讯。 Intentional radiators transmitting information must be certified under the appropriate Part 15 Rules and will generally require an equipment certification. A WPT device may operate in two different modes: charging and communications. It is possible for the device to be approved under Part 18 for the charging mode and Part 15 for the communications mode, if it can be shown that (1) the device complies with the relevant rule parts; and (2) the functions are independent. Part 18 consumer devices can be authorized using either certification or SDoC, once the appropriate RF exposure evaluation has been completed. 充电模式可以做part 18， 通讯模式可以做part 15. 这两个标准都需要增加RF exposure evaluation。 Note：请参考RSS-216 Section 2 CE 认证标准： R&TTE指令中，ETSI 针对无线充电器在EN300 330-1 V1.8.1中有规定 新的RED已经将无线充电器划分到了EN303 417. Note: 无线充电器北京论坛一定要有Radio Communication or Radio Determination功能才属于EN303 417的范畴。如果仅仅是充电功能的话，那么就应该符合EMCD。 FCC 认证标准（KDB680106 D01）: Wireless power transfer (WPT) devices operating at frequencies above 9 kHz are intentional radiators and are subject to either Part 15 and/or Part 18 of the FCC rules. The specific applicable rule part depends on how the device operates, and if there is communication between the charger and device being charged. 无线充电器是指不用传统的充电电源线连接到需要充电的终端设备上的充电器，采用电磁感应原理，通过线圈进行能量耦合实现能量的传递。从理论来说，无线充电技术对人体安全无害处，无线充电使用的共振原理是磁场共振，只在以同北京论坛一频率共振的线圈之间传输，而其他装置无法接受波段。但是它在正常工作下会产生电磁场，所以也要满足相应的EMC要求。
