引 言
目前许多电子电气产品由于功能需要和生产技术的局限,仍含有大量如铅、汞、镉、六价铬、多溴联
苯和多溴二苯醚等限用物质。这些含限用物质的电子电气产品在废弃之后,如处置不当,不仅会对环境
造成污染,也会造成资源的浪费。
为了促进电子电气行业的可持续发展以及电子电气产品的资源节约,环境保护,工业和信息化部等
政府部门联合制定了电子电气产品污染控制相关规章,将电子电气产品的污染控制工作纳入法制化轨
道。为了配合有关规章更好地实施,指导电子电气产品供应链上的制造厂商从源头控制限用物质的使
用以符合相关法律规范性文件的要求,推动电子电气行业加快限用物质的替代和减量化,特制定本
标准。
电子电气产品中限用物质的限量要求

(质量分数),镉的含量不得超过0.01%(质量分数)。
5 检验方法
5.1 检测单元分类
为了确定电子电气产品是否符合第4章要求,按照尽可能拆分成均质材料的基本原则,首先将电子
电气产品按附录A要求拆分成检测单元,并按表1进行分类。当分类有重合或矛盾时,应该依照EEP-
A/EEP-B/EEP-C的顺序进行归类,即如果能按EEP-A归类的则不宜归为EEP-B或EEP-C类。
表1 检测单元分类
检测单元类别 检测单元类别定义
EEP-A 构成电子电气产品的各均质材料
EEP-B 电子电气产品中各部件的金属镀层
EEP-C 电子电气产品中现有条件不能进一步拆分的小型零部件或材料a
a 体积小于或等于4mm3 的单元,例如贴片电阻器,贴片电容器等。
5.2 限用物质含量测定方法
依照GB/T 26125-2011中检测方法对各检测单元的限用物质含量进行测定。
6 符合性判定规则
如果电子电气产品中拆分出的各检测单元中限用物质含量符合表2要求,则判该电子电气产品合
格;如果任意一检测单元中限用物质含量不符合表2的要求,则判为不合格。
