Touch screen RoHS certification is a kind of environmental protection certification for touch screen products, which aims to limit the content of certain hazardous substances used in touch screen products in order to protect human health and the environment. The following is a detailed introduction to the RoHS certification of touch screen:
1. Background and purpose of RoHS certification
RoHS, known as Restriction of Hazardous Substances Directive, is an EU regulation for electrical and electronic products. The main purpose of this regulation is to restrict the content of lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr6+), polybrominated biphenyls (PBBs), polybrominated diphenyl ethers (PBDEs) and other hazardous substances in electrical and electronic products, in order to minimize the potential threat to human health and the environment caused by these substances.
2. The RoHS certification for touch panels mainly restricts the content of the following hazardous substances:
Lead (Pb): shall not exceed 0.1%.
Mercury (Hg): shall not exceed 0.1%.
Cadmium (Cd): shall not exceed 0.01%.
Hexavalent chromium (Cr6+): not more than 0.1%.
Polybrominated biphenyls (PBBs): not to exceed 0.1%.
Polybrominated diphenyl ethers (PBDEs): not to exceed 0.1%.
Tetrabromobisphenol A (TBBPA): not more than 0.1%.
Alkyl benzene sulfonate (LAS): not more than 0.1%.
Tris pyrophosphate (TPP): not more than 0.1%.
Diphenyl Silicon Oxide (DSO): Specific content limits may change due to updates to the standard, please refer to the latest RoHS directive.
3. The RoHS certification process for touch panels usually includes the following steps:
3.1 Understanding RoHS Directive Requirements: Before you start, make sure you understand the specific requirements of the RoHS Directive, including the types of restricted substances, content limits, etc.
3.2 Select RoHS Certification Body: Select a recognized RoHS certification body to ensure that the organization is qualified to perform RoHS certification and can provide the required services.
3.3 Prepare necessary documents: Collect and prepare relevant documents, including technical specifications of the touch panel, bill of materials, supplier's declaration, test reports, etc.
3.4 Submit the application and contact the certification body: Submit the application at the chosen RoHS certification body and contact them to understand the specific application process, documentation requirements and testing schedule.
3.5 Document Evaluation: The certification body will evaluate the submitted documents to ensure that they comply with the requirements of the RoHS Directive.
3.6 Sample Testing: Samples of the touch screen are provided for testing of restricted substance content as needed. Testing typically includes analysis using methods such as X-ray fluorescence spectroscopy (XRF).
3.7 Field Inspections (if required): In some cases, the certification body may conduct field inspections to verify the manufacturing process and information in the documentation.
3.8 Audits and Reviews: The certification body may conduct audits and reviews to ensure that the product meets the requirements for RoHS certification. This may include a review of the supply chain.
3.9 Issuance of Certificate: If all evaluations and tests are passed, the certification body will issue a RoHS Compliance Certificate that the touchscreen product meets the requirements of the RoHS Directive.
3.10 Ongoing Compliance: RoHS certification is not a one-time effort. Ongoing monitoring and management is the key to ensure that touch screen products continue to comply with the RoHS Directive throughout their life cycle.
4. Significance of RoHS Certification
The implementation of RoHS certification of touch screen helps to promote environmentally friendly design and production of touch screen products and promote sustainable development. At the same time, it also helps to protect consumer health and the environment and reduce the negative impact of e-waste on the environment. For touch panel manufacturers, obtaining RoHS certification is one of the necessary conditions to enter the EU market and an important means to enhance product competitiveness and brand image.
In summary, RoHS certification for touch panels is an important measure to ensure that touch panel products comply with EU environmental regulations. By following the RoHS certification process and requirements, touch panel manufacturers can produce more environmentally friendly and safer products, bringing consumers a better experience.
