What are the rohs six hazardous substances?

rohs six hazardous substances are:

1, liquid mercury (mercury) application of the chemical substance examples: temperature controllers, sensors, power switches and automotive relays, light bulbs.

2. Examples of the application of lead as a chemical substance: soldering materials, laminated glass, and PVC thickening agents.

3. Examples of the application of cadmium as a chemical substance: power switches, bullet yellows, radio-frequency connectors, housings and PCBs, circuit breakers, and rechargeable batteries.

4. Examples of application of chromium (hexavalent): Metal materials with etching plating.

5. Examples of the application of polybrominated biphenyls (PBB): Halogen-free flame retardants, PCBs, radio frequency connectors, and plastic enclosures.

6, polybrominated diphenyl ether (PBDE) examples of the application of this chemical: non-halogenated flame retardants, PCB, radio frequency connectors, plastic enclosures.

Testing Standards:

Based on the EU's national WEEE&RoHS order, the AOV is based on the material to carry out the splitting of the goods to different materials to carry out their own test of harmful substances.

Metal materials need to test four hazardous chemical elements such as (Cd cadmium / Pb lead / Hg mercury / Cr6 hexavalent chromium).

Plastic materials in addition to checking the four hazardous heavy metal elements also need to test the brominated non-halogenated flame retardants (polybrominated biphenyls PBB / polybrominated diphenyl ether PBDE).

Additionally, the packaging products of different materials must be carried out individually to detect heavy metals in packaging products (94/62/EEC).
