        Must-read at the Exit: Why Do Chargers Need CB Certification? After reading this, you'll avoid taking unnecessary detours

        Author:中認(rèn)聯(lián)科 time:2025-11-26 Ctr:645

        As the "energy replenishment station" of electronic devices, the safety performance of the charging head is directly related to the user's safety during use and the lifespan of the equipment. As an international safety certification under the IECEE (International Electrotechnical Commission Organization for Conformity Testing and Certification of Electrical Products) system, the CB certification covers the standards of over 50 countries and regions around the world, achieving "one-time certification, mutual recognition in multiple countries", and serves as an important pass for charging heads to enter the international market.

        Why do charging heads need to obtain CB certification? Firstly, it serves as the basis for market access in the international market. When most countries import electrical products, they will recognize the CB certification report as a safety and compliance basis, which can significantly simplify the local certification process. Secondly, it can effectively ensure product safety. The certification process will strictly test key indicators such as the electrical strength, temperature rise, and short-circuit protection of the charging head, reducing potential safety hazards such as fire and leakage. Finally, it helps enhance the competitiveness of enterprises. Products with the CB certification mark can convey a signal of compliance and reliability to the market, and increase the trust of consumers and partners.

        To apply for CB certification of the charging head, the following materials need to be prepared: 1. Detailed product manual (including electrical parameters and usage scenario description); 2. Electrical schematic diagram, PCB layout diagram and component layout diagram; 3. List of key components (such as transformers, capacitors, etc.) and corresponding certification certificates; 4. Sample sheets of product nameplates and labels; 5. Test samples (usually 2-3 units, which need to be consistent with the mass production); 6. Basic qualification documents such as business licenses of enterprises.

        The certification process is clear and easy to understand: The first step is consultation and assessment. Communicate with the engineers of China Certification and Accreditation Union about the product situation to confirm the certification standards and cycle. The second step is to submit the materials. Organize the above-mentioned materials and submit them for review to ensure that the documents are complete and standardized. The third step is sample testing. Send the samples to the recognized laboratory for full-item testing in accordance with the IECEE CB Scheme standard. The fourth step is report review. After the test is qualified, a test report will be issued and reviewed and confirmed by the certification body. Step 5: Certificate issuance. After the review is passed, the CB certification certificate and report will be issued, and subsequent certificate transfer services will be supported.
