What is RoHS Compliance Certification?

What is ROHS Testing? 

RoHS stands for "Restriction of Hazardous Substances." It is a regulation established by the European Union (EU) to limit the use of certain hazardous chemicals in electrical and electronic equipment (EEE) to protect the environment and human health. 

Companies producing these products must undergo RoHS testing to ensure no restricted toxic substances are used in their products. Currently, RoHS regulations prohibit 10 substances, and manufacturers must comply to sell their products in the EU market. 

The 10 Restricted Substances and Their Maximum Concentrations: 

1. Lead (Pb): < 0.1% 

2. Mercury (Hg): < 0.1% 

3. Cadmium (Cd): < 0.01% 

4. Hexavalent Chromium (Cr6+): < 0.1% 

5. Polybrominated Biphenyls (PBB): < 0.1% 

6. Polybrominated Diphenyl Ethers (PBDE): < 0.1% 

7. Di(2-ethylhexyl) Phthalate (DEHP): < 0.1% 

8. Benzyl Butyl Phthalate (BBP): < 0.1% 

9. Dibutyl Phthalate (DBP): < 0.1% 

10. Diisobutyl Phthalate (DIBP): < 0.1% 

How Is RoHS Testing Conducted?

RoHS Compliance is assessed by detecting hazardous chemical substances through testing. Two common methods include: 

1. XRF Spectrometry (X-Ray Fluorescence): 

   - How it works: High-energy X-rays are directed at a sample, exciting the material to emit secondary fluorescence X-rays. The emitted rays are analyzed to identify the elements and their concentrations. 

   - Advantages: 

     - Rapid detection of heavy metals like lead. 

     - Suitable for homogeneous materials (e.g., solid plastics or metals). 

     - Low cost, making it a popular choice for manufacturers. 

2. Chromatography: 

   - How it works: Chemical methods are used to separate mixtures, enabling the analysis of specific components and their concentrations. 

   - Applications: 

     - Used to detect PBB, PBDE, and phthalates. 

     - Particularly effective for non-homogeneous materials or trace levels of specific chemicals. 

How to Obtain RoHS CoC or DoC?

- Certificate of Conformity (CoC): 

  Certifies that your product has been tested in a laboratory and complies with RoHS standards. 

- Declaration of Conformity (DoC): 

  A self-declaration by suppliers, based on test results, stating that their products meet RoHS requirements. 

To obtain a CoC, suppliers must commission reliable laboratories to test their products. CoC is issued by the laboratory, while DoC is a formal commitment from the supplier.
