What is ROHS certification? ROHS certification Review, Features

ROHS certification refers to the EU Restriction of Hazardous Substances directive (abbreviated as ROHS) for the restriction of the use of certain hazardous substances in electrical and electronic equipment.

About ROHS Certification

• The ROHS Directive came into effect in the European Union in 2003, aiming to limit the content of six hazardous substances used in electrical and electronic equipment, including lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers, and specifically stipulates that the lead content cannot exceed 0.1%. These hazardous substances have potential risks to the environment and human health, so ROHS certification aims to protect consumers and the environment and promote sustainable development.

• The implementation of ROHS certification can ensure that electronic and electrical equipment meets relevant standards by testing the content of these hazardous substances, thereby obtaining the ROHS certification mark.

• ROHS certification requires that all electronic and electrical products entering the EU market must comply with this standard to ensure product safety and environmental protection.

RoHS Applicable Products

ROHS certification applies to all electronic and electrical products entering the European Union market, including but not limited to the following types:

1. Large household appliances: such as refrigerators, washing machines, air conditioners, etc.

2. Small household appliances: such as vacuum cleaners, electric irons, electric fans, etc.

3. Information technology equipment: such as computers, laptops, printers, etc.

4. Communication equipment: such as mobile phones, telephones, modems, etc.

5. Audio-visual equipment: such as televisions, stereo equipment, video recorders, etc.

6. Lighting equipment: such as table lamps, floor lamps, street lamps, etc.

7. Industrial control equipment: such as automation equipment, industrial robots, etc.

8. Medical equipment: such as X-ray machines, ultrasonic diagnostic equipment, etc.

9. Measuring and testing equipment: such as thermometers, pressure gauges, electric meters, etc.

10. Automobiles and their accessories: such as automotive electronics, engine control systems, etc.

It should be noted that in ROHS certification, some products can be exempted or specially regulated, and these specific standards can be found in relevant regulations and guidelines.

RoHS Certification Fee Charging Method

ROHS testing is charged based on material and color, because the product needs to be separated according to material during the test. Different materials need to be tested for harmful substances, and packaging materials of different materials need to be tested separately, so the charges are the same.

Six hazardous substances restricted by ROHS certification

1. Lead (Pb): Lead is mainly used in welding and the production of electronic equipment. Long-term exposure to high concentrations of lead can cause multiple damages to the human body, including nerves, blood, and kidneys.

2. Mercury (Hg): Mercury is mainly used in electronic products such as fluorescent lamps, batteries, and thermometers. Long-term exposure to mercury may cause health problems such as damage to the nervous system and breathing difficulties.

3. Cadmium (Cd): Cadmium is mainly used in electronic products such as batteries, voltage regulators, and semiconductor devices. Long-term exposure to cadmium can cause health problems such as bone and joint pain and osteoporosis.

4. Hexavalent chromium (Cr6+): Hexavalent chromium is mainly used for rust prevention and purification. If used improperly, it will cause air, water and soil pollution, and thus affect the health of humans and other organisms.

5. Polybrominated biphenyls (PBB): Polybrominated biphenyls are mainly used in plastics, rubber and other products. Long-term exposure to PBB may cause health problems such as hormone imbalance and reproductive development defects in humans.

6. Polybrominated diphenyl ethers (PBDE): Polybrominated diphenyl ethers are mainly used in plastics, rubber, coatings and other products. Long-term exposure to PBDE may cause health problems such as damage to the nervous system and reproductive dysfunction.
