Reduction & elimination of environmentally sensitive materials
环境敏感物质的减少与消除
What it requires 要求
Full conformity with the EU RoHS Directive including declared exemptions; no intentionally added mercury in display backlights; limits on lead, cadmium, hexavalent chromium and specified brominated flame retardants. Optional points reward eliminating halogenated flame retardants and PVC from enclosures, cables and printed circuit boards, restricting phthalates and certain fluorinated substances, and running a documented chemical alternatives assessment so that a removed substance is not replaced by something worse.
完全符合欧盟 RoHS 指令并申报所适用豁免;显示器背光不得有意添加汞;对铅、镉、六价铬及指定溴系阻燃剂设限。加分项包括:外壳、线缆与印刷电路板去卤化阻燃剂与去 PVC,限制邻苯二甲酸酯及特定含氟物质,并执行有据可查的替代物评估,确保"去掉一个坏的"不会"换来一个更坏的"。
How to achieve 达成路径
- Collect full material declarations down to homogeneous-material level using IEC 62474 / IPC-1752A formats — not PDF certificates.采用 IEC 62474 / IPC-1752A 数据格式,收集到均质材料层级的全成分申报,而非仅要 PDF 证书。
- Maintain one internal restricted-substance list that is stricter than law, and write it into the supplier contract and the drawing.建立一份严于法规的内部受限物质清单,并写入供应商合同与工程图纸。
- Screen every proposed substitute with a hazard-assessment method such as GreenScreen before qualifying it.任何替代物在导入前,先用 GreenScreen 等危害评估方法筛查。
- Verify with lab data — XRF screening plus GC-MS / ICP confirmation on high-risk parts, sampled per production lot.以实验室数据验证:高风险零件按批次做 XRF 初筛 + GC-MS / ICP 确认。
- Log every RoHS exemption you rely on with its expiry date, and open a redesign task before it lapses.登记所引用的每项 RoHS 豁免及其到期日,并在失效前提前立项重新设计。
