ROHS 2.0 Testing Project

ROHS 2.0 Testing Project

The ROHS 2.0 standard includes testing for the following 10 substances:

1. Lead (Pb)

   • Usage examples: solder, glass, PVC, stabilizer

2. Cadmium (Cd)

   • Usage examples: switch, spring, connector, housing, PCB, contact, battery

3. Mercury (Hg)

   • Usage examples: temperature controller, sensor, switch and relay, light bulb

4. Hexavalent Chromium (Cr6+)

   • Usage example: Metal corrosion coating

5. Polybrominated Biphenyls (PBBs)

   • Usage examples: flame retardants, PCBs, connectors, plastic casings

6. Polybrominated Diphenyl Ethers (PBDEs)

   • Usage examples: flame retardants, PCBs, connectors, plastic casings

7. Diisobutyl Phthalate (DIBP)

   • Usage: As a plasticizer for PVC, it can replace DBP and is also used as a plasticizer for cellulose resin, vinyl resin, nitrile rubber, and chloroprene rubber.

8. Phthalate (2-Ethylhexyl Ester) (DEHP)

   • Usage: Mainly used as a plasticizer for PVC, but also as an electrolyte for ceramics or capacitors in electronic products.

9. Dibutyl Phthalate (DBP)

   • Usage: Used in conjunction with other plasticizers for PVC components such as cables, sockets, pipes, shock absorbers, as well as in some non-polymer materials such as paint, adhesives, sealants, and printing inks.

10. Butyltoluene Phthalate (BBP)

    • Usage: Transparent oily liquid, used as a plasticizer for polyvinyl chloride, vinyl chloride copolymer, cellulose resin, natural and synthetic rubber.

ROHS Certification Exemption Situation

ROHS certification does not require all electronic products to meet the requirements of the directive for toxic and harmful substance content. The following are some EU exempted products:

1. Mercury content in fluorescent lamps:

   • Compact fluorescent lamps shall not exceed 5 milligrams per lamp;
   • In general purpose straight fluorescent lamps, salt phosphate straight fluorescent lamps shall not exceed 10 milligrams per lamp, normal service life triphosphate straight fluorescent lamps shall not exceed 5 milligrams per lamp, and long-term service life triphosphate straight fluorescent lamps shall not exceed 8 milligrams per lamp;
   • Mercury content in special purpose straight fluorescent lamps.

2. Mercury content in lighting fixtures:

   • Mercury content in other lighting fixtures not specifically mentioned.

3. The lead content in the glass of cathode ray tubes, electronic components, and fluorescent tubes.

4. The lead content in alloy elements in steel is less than 0.35%, the lead content in alloy elements in aluminum is less than 0.4%, and the lead content in alloy elements in copper is less than 4%.

5. Lead in high melting temperature solder materials, such as tin-lead solder alloys with lead content exceeding 85%; Lead in solder used for servers, storage, and storage array systems; Lead in solder in network infrastructure equipment used for exchange, signal and transmission, as well as telecommunications network management; Lead in electronic ceramic components (such as piezoelectric ceramics).
