CB Certification Process
CB Certification Process
1. What is CB Certification?
CB certification is a globally recognized system established by the International Electrotechnical Commission (IECEE). A single test and certification allows for multi-country recognition, simplifying the process for electronic and electrical products to enter different countries.
Core Documents: CB Test Certificate (CBTC) + CB Test Report (CBTR).
2. Which Products Does CB Certification Cover?
Mainly includes:
Household appliances (e.g., refrigerators, air conditioners)
Information technology equipment (e.g., computers, power supplies)
Lighting and photovoltaic products
Electronic components (e.g., plugs, switches)
Note: Specific scope refers to the product categories published by IECEE (e.g., IEC 60335, IEC 60950, etc.).
3. What is the CB Certification Process?
Select an NCB body: such as an authorized laboratory like UL, TÜV, or CQC.
Submit an application: Provide product information (circuit diagrams, specifications, etc.).
Testing and rectification: Testing is conducted according to IEC standards; any non-conformities must be rectified.
Issuance of Certificate: Upon successful completion, you will receive both CBTC and CBTR. 4. Is a factory inspection required for CB certification?
Usually not, but some countries may require a factory inspection during the certification transfer process (e.g., India, Brazil).
Must comply with ISO 9001 or other quality management system requirements.
5. How long is a CB certificate valid?
No fixed validity period, but 3 years is generally accepted.
If IEC standards are updated or products change, retesting or a supplementary report is required.
6. What are the costs of CB certification?
Costs vary depending on product complexity, testing standards, and the NCB body, and typically include:
Testing fees (main standard + differential standards)
Application fees, certificate fees
Optional services (e.g., expedited processing, pre-testing).
Example: Approximately 10,000 to 30,000 RMB for ordinary household appliances.
7. How to use a CB report to transfer certifications to various countries?
EU (CE): CB report + compliance with EU directives (e.g., LVD, EMC).
Australia (SAA): Submit the CB report to an Australian body for review. South Korea (KC): Requires supplementary local safety testing.
Tip: Confirm any additional requirements of the target country in advance (e.g., language, labeling).
8. What are the differences between CB, CE, UL, etc. certifications?
CB: Internationally recognized report, requires conversion to local certification.
CE: Mandatory entry into the EU, includes safety and EMC requirements.
UL: Voluntary in the US market (mandatory for some products), standards are ANSI/UL.
9. Common reasons for failure?
Product design does not comply with IEC standards (e.g., insufficient insulation distance).
Test samples do not match documentation.
Failure to respond to standard updates in a timely manner (e.g., IEC 62368-1 replacing 60950).
10. How to choose an NCB organization?
Check qualifications: Confirm whether the organization is accredited in the target country (e.g., CQC accredits China and South Korea).
Check experience: Prioritize organizations familiar with your product category.
Check services: Does the organization provide one-stop certification conversion support?
