This report is based onEU RoHS Directive 2011/65/EU and its amended Directive (EU) 2015/863Covering ten substances:
In terms of limit values,Cadmium is 100 mg/kg, while the other nine are all 1000 mg/kg。
The detection method refers to the IEC 62321 series (ICP-OES/AAS, UV Vis, GC-MS). The results are as follows:
| Testing Items | limit | unit | MDL (detection limit) | result |
|---|---|---|---|---|
| Lead Pb | 1000 | mg/kg | 2 | ND |
| Mercury Hg | 1000 | mg/kg | 2 | ND |
| Cadmium Cd | 100 | mg/kg | 2 | ND |
| Hexavalent chromium Cr (VI) | 1000 | mg/kg | 8 | ND |
| Sum of polybrominated biphenyls PBB | 1000 | mg/kg | — | ND |
| Sum of polybrominated diphenyl ethers PBDE | 1000 | mg/kg | — | ND |
| DEHP | 1000 | mg/kg | 50 | ND |
| BBP | 1000 | mg/kg | 50 | ND |
| DBP | 1000 | mg/kg | 50 | ND |
| DIBP | 1000 | mg/kg | 50 | ND |
All ten items are ND (not detected).

A: I can’t. This report is only responsible for the sample submitted for inspection, and corresponding reports for other models/batches need to be provided separately.
