The EU RoHS testing process for laptops involves multiple steps to ensure that the product meets the EU's environmental requirements. The following is a detailed testing process:

1. Self-assessment

- Understand the material composition of the product: The company needs to conduct a detailed analysis of the material composition of the laptop to ensure that it does not contain hazardous substances restricted by the RoHS directive.

- Supply chain situation: Confirm the composition of all materials in the supply chain and obtain a RoHS compliance declaration.

2. Select a certification body

- Qualifications and experience: Select a certification body with qualifications and experience, such as Shenzhen Dezewei Technology Testing Co., Ltd.

- Sign a contract: Sign a formal certification contract with the certification body to clarify the rights and obligations of both parties.

3. Prepare application materials

- Product manual: Provide a detailed product manual or user manual to explain the product's functions, uses, operating methods, etc.

- Circuit schematic: Provide a circuit schematic of the laptop so that the tester can understand the circuit structure and composition of the product.

- Parts list (BOM): List all components and materials included in the product in detail.

- PCB diagram (front and back): Provide the PCB board diagram of the laptop, including the front and back.

- Certification application form: Fill in and submit the certification application form.

- Supply chain management materials: Provide the composition of all materials confirmed with the supplier and the RoHS compliance statement.

- Laboratory information: If a third-party laboratory is selected for testing, the name, address and qualification certification information of the testing laboratory need to be provided.

4. Submit application

- Pay fees: Submit an application to the certification body and pay the relevant certification fees.

- Provide samples: Generally, 2-3 laptops are required as test samples.

5. Sample testing

- Test items: The test items include lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium (Cr6+), polybrominated biphenyls (PBBs) and polybrominated diphenyl ethers (PBDEs).

- Test time: Generally, the test is completed within one week.

6. Review and evaluation

- Technical document review: The certification body reviews and evaluates the company's technical documents, production processes, etc.

- Production process evaluation: Ensure that the company's production process complies with the RoHS certification standards.

7. Issuance of certificates

- Certificate of conformity: If the product complies with the RoHS certification standards, the certification body will issue a RoHS certification certificate to the company.

- Marking the certification mark: The company can mark the RoHS certification mark on the product.

8. Subsequent maintenance

- Regular audits: The company needs to conduct regular self-audits to ensure that the product continues to comply with the requirements of the RoHS Directive.

- Update materials: If the product materials change, the certification materials need to be updated in a timely manner and re-tested.

Through the above process, the company can ensure that the laptop computer complies with the requirements of the EU RoHS Directive and enter the EU market smoothly.
