A calculator is an electronic device that can perform mathematical operations. The calculator needs to undergo EU RoHS testing. The EU RoHS testing project for calculators is mainly to ensure that calculators do not contain harmful substances during manufacturing and use to protect the environment and human health.
Calculator EU ROHS testing items:
1. Lead (Pb):
Limit value: There is no specific number, but it is necessary to ensure that the lead content in the calculator does not exceed the specified limit.
Application examples: solder, glass, PVC stabilizer, etc.
2. Cadmium (Cd):
Limit value: There is no specific number, but you need to ensure that the cadmium content in the calculator does not exceed the specified limit.
Application examples: switches, springs, connectors, housings and PCBs, contacts, batteries, etc.
3. Mercury (Hg):
Limit value: No specific number, but make sure the mercury content in the calculator does not exceed the specified limit.
Application examples: thermostats, sensors, switches and relays, light bulbs, etc.
4. Hexavalent chromium (Cr6+):
Limit value: There is no specific number, but you need to ensure that the hexavalent chromium content in the calculator does not exceed the specified limit.
Application examples: metal with corrosion coating, etc.
5. Polybrominated biphenyls (PBBs) and polybrominated diphenyl ethers (PBDEs):
Limit value: There is no specific number, but you need to ensure that the content of these two substances in the calculator does not exceed the specified limit.
Application examples: flame retardants, PCBs, connectors, plastic housings, etc.
6. Diisobutyl phthalate (DIBP):
Limit value: There is no specific number, but you need to ensure that the content of the substance in the calculator does not exceed the specified limit.
Application examples: Used as a plasticizer for PVC, as well as for cellulose resin, vinyl resin, nitrile rubber and chloroprene rubber.
7. Phthalic acid (2-ethylhexyl ester) (DEHP):
Limit value: There is no specific number, but you need to ensure that the content of the substance in the calculator does not exceed the specified limit.
Application examples: Mainly used as PVC plasticizer, such as insulators in cables and wires.
8. Dibutyl phthalate (DBP):
Limit value: There is no specific number, but you need to ensure that the content of the substance in the calculator does not exceed the specified limit.
Application examples: Mainly used in PVC parts with other plasticizers, such as cables, sockets, pipes, shock absorbers, etc.
9. Butyl benzyl phthalate (BBP):
Limit value: There is no specific number, but you need to ensure that the content of the substance in the calculator does not exceed the specified limit.
Application examples: Used as a plasticizer in PVC flooring, may also be present in synthetic leather, textile coatings, PVC materials, printing inks, sealants and adhesives in electrical and electronic equipment.
