环境有害物质PPT

(ROHS/REACH）知识培训-有害物质等环保基础

什么是RoHS标准?

欧盟共同体于2003年2月13日通过的RoHS标准，此标准是为了限制在电器电子设备中使用危险物质。

RoHS:欧盟的第2002/95/EC号关于在电子电器设备中限制使用某些有害物质的指令。

Restriction ofthe use of certain Hazardous Substance(RoHS) in Electrical Equipment.

ROHS指令在对特定有毒有害物质提出限制的同时,亦充分考虑了技术可行的原则，如果某物质的去除或通过改变设计而使用替代品在技术上可行，或替代品对环境、健康和/或消费者安全造成的负面影响超过带来的益处时，可设立一定的豁免可设立一定的豁免。

豁免的含义一对限制有害物质管控的免除。
