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.

In modern electronic product manufacturing, RoHS (Restriction of Hazardous Substances) testing is increasingly vital, particularly for companies aiming to enter the EU market. RoHS testing ensures environmental compliance, enhances market competitiveness, and strengthens brand reputation. Today, the editor from Huabiao Testing provides a detailed analysis of the ten substances tested under RoHS, offering insights from a professional testing agency’s perspective.

Overview of RoHS Testing

The RoHS Directive (2011/65/EU, amended by 2015/863/EU) regulates the use of hazardous substances in Electrical and Electronic Equipment (EEE), including components and raw materials. RoHS testing verifies that 10 hazardous substances in homogeneous materials (materials that cannot be mechanically separated) are below specified limits, protecting human health and the environment. Compliance requires technical documentation, a Declaration of Conformity (DoC), and, where applicable, the CE mark for EU market entry.

The ten substances tested under RoHS are:

1. Lead (Pb)

2. Cadmium (Cd)

3. Mercury (Hg)

4. Hexavalent Chromium (Cr VI)

5. Polybrominated Biphenyls (PBBs)

6. Polybrominated Diphenyl Ethers (PBDEs)

7. Diisobutyl Phthalate (DIBP)

8. Dibutyl Phthalate (DBP)

9. Butyl Benzyl Phthalate (BBP)

10. Di(2-ethylhexyl) Phthalate (DEHP)

These substances are restricted due to their potential harm to human health and the environment. For instance, heavy metals like lead, cadmium, and mercury can accumulate in the body, damaging the nervous system, kidneys, or other organs. Brominated flame retardants (PBBs, PBDEs) may cause endocrine disruption or reproductive toxicity, while phthalates (DIBP, DBP, BBP, DEHP) are linked to hormonal and developmental issues.

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 not only pertains to environmental compliance but also directly impacts a company’s market competitiveness and brand image. Today, the editor from Huabiao Testing shares insights on what RoHS testing entails and how to obtain RoHS certification for 3D printers.

What is RoHS Testing?

RoHS is a regulation introduced by the European Union to restrict the use of hazardous substances in electronic products. It encompasses the 2011 version and its 2015 amendment. The regulation applies to various electronic products, including 3D printers. RoHS restricts 10 hazardous substances, such as lead, mercury, and cadmium, prohibiting their use in electronic products to ensure safety for both humans and the environment. If you plan to sell 3D printers in the EU, RoHS certification is mandatory, and it is also significant in many other countries.

How to Obtain RoHS Certification for 3D Printers?

1. Consultation and Preparation: Contact a professional testing agency, such as Ningbo Huabiao Testing Co., Ltd., and submit the 3D printer’s product specifications, Bill of Materials (BOM), samples, and target market information (primarily the EU).

2. Sample Testing: The testing agency will use equipment such as XRF (X-ray Fluorescence Spectrometer) and ICP-MS (Inductively Coupled Plasma Mass Spectrometry) to test for hazardous substances. The process typically takes 5–15 working days, depending on the product’s complexity and the number of components.

3. Results Review: After testing, the company receives a RoHS compliance report. If non-compliance is found, materials or suppliers must be adjusted, and retesting is required.

4. Technical Documentation: Prepare RoHS technical documentation, including the test report, material declarations, and a Declaration of Conformity (DoC), for EU market access or customer audits.

5. Market Access: Submit the RoHS compliance report and technical documentation to meet the requirements of the EU market or other regions, as well as importers or e-commerce platforms (e.g., Amazon).
