What are the 10 substances restricted under RoHS? How to handle RoHS testing for water purifier filter casings?

In modern electronic product manufacturing, RoHS (Restriction of Hazardous Substances) testing is becoming increasingly important, especially for companies planning to enter the EU market. RoHS testing is not only about environmental compliance but also directly impacts a company's market competitiveness and brand image. Today, the Huabiao Testing team will share with you: What are the 10 substances restricted under RoHS? How to handle RoHS testing for water purifier filter casings?

What are the 10 substances restricted under RoHS?

The RoHS Directive (Directive 2011/65/EU and its amendment 2015/863) is a regulation established by the EU in 2002 and implemented in 2006. It aims to restrict the use of specific hazardous substances in electrical and electronic equipment to protect human health and the environment. RoHS applies to a wide range of products, including household appliances, consumer electronics, industrial equipment, medical devices, and more. If a water purifier filter casing contains electrical or electronic components (such as control circuits or displays), it must also comply with RoHS requirements.

The 10 substances restricted under RoHS:

1. Lead (Pb): 0.1% (1000 ppm), commonly used in solder, coatings, and plastic stabilizers.

2. Mercury (Hg): 0.1% (1000 ppm), often found in fluorescent lamps and switches.

3. Cadmium (Cd): 0.01% (100 ppm), used in electroplating, pigments, and batteries.

4. Hexavalent Chromium (Cr6+): 0.1% (1000 ppm), used in anti-corrosion coatings and chrome plating.

5. Polybrominated Biphenyls (PBB): 0.1% (1000 ppm), used as flame retardants in plastics.

6. Polybrominated Diphenyl Ethers (PBDE): 0.1% (1000 ppm), used as flame retardants in plastics.

7. Bis(2-ethylhexyl) Phthalate (DEHP): 0.1% (1000 ppm), used as a plasticizer in plastics.

8. Benzyl Butyl Phthalate (BBP): 0.1% (1000 ppm), used as a plasticizer in plastics.

9. Dibutyl Phthalate (DBP): 0.1% (1000 ppm), used as a plasticizer in plastics.

10. Diisobutyl Phthalate (DIBP): 0.1% (1000 ppm), used as a plasticizer in plastics.

Why does a water purifier filter casing need RoHS testing?

Water purifier filter casings are typically made of plastic (e.g., SAN, PP) or metal and may contain electronic components (e.g., control panels, sensors). These parts might use materials containing lead solder, plasticizers, or flame retardants, necessitating RoHS testing to ensure:

1. Compliance: Meets EU RoHS Directive requirements, enabling the CE mark and legal entry into the EU market.

2. Safety: Ensures the casing materials do not release hazardous substances, protecting user health.

3. Environmental Responsibility: Reduces pollution from electronic waste, promoting sustainable development.

4. Market Competitiveness: Enhances consumer trust through RoHS compliance, avoiding recalls or fines.
