以IEC/EN 60598-2-12夜灯标准为例:
$ K! t- {' ~2 {' }12.6.8 Mains socket-outlet mounted nightlights shall not have a cover that is shaped and/ordecorated so that it is likely to be treated as a toy by children.1 i$ N% r7 e, M& B
用的是AND/OR,即夜灯外盖的形状,或装饰,或形状+装饰,不能被儿童视为玩具。: O: Z% Z7 p4 f& O( }; W- U
近三年关于夜灯的欧盟通报中,充分说明了这一点,足球形状的被通报,带个卡通图画的也被通报。
