What is CB Certification Testing?

1. Introduction to Certification

The IECEE-CB system is a globally recognized system established by the International Electrotechnical Commission (IEC) for the safety testing and certification of electrical products. Its purpose is to reduce international trade barriers resulting from the need to meet various national certification or approval standards. The CB system recognizes test results for 19 categories of electrical products, including information technology equipment, household appliances, and medical electrical devices, based on IEC safety and electromagnetic compatibility (EMC) standards approved by IECEE.

The foundation of the CB system is to ensure that the safety test results of electronic and electrical equipment are globally accepted. Upon successful testing, a CB test certificate and corresponding CB test report are issued for the product. Together, these documents serve as a passport for manufacturers to apply for global certification from national certification bodies in any CB participating country or region, often without the need for additional testing.

3. Product Scope

Currently, the CB system covers 14 major categories and 180 types of products, including video game devices, testing equipment, power cables, capacitors and components, lighting, household appliances, protective devices, transformers, office and IT equipment, AV equipment, and medical devices.

7. Certification Process

1. Application  

(1) Confirm customer information;  

(2) Complete the CB application form;  

(3) Provide specifications and other documents.  

2. Quotation  

Determine testing time and costs based on provided information.  

3. Payment  

Upon confirmation of the quote, the applicant signs the application form and service agreement and pays the project fee.  

4. Sample Submission  

The customer sends samples.  

5. Testing  

The laboratory conducts CB certification tests according to relevant standards.  

6. Report  

Upon passing the tests, the CB report is completed.  

7. Certification  

The report is submitted to the certification body (NCB) for review and, upon approval, a CB certificate is issued.  

8. Certification Cycle and Validity

The CB certification cycle takes 4-5 weeks. While there is no explicit validity period for CB certification, recognized NCBs generally raise concerns over CB certificates issued more than three years ago.

9. Factory Inspection

Factory inspections are not required for CB certification.

10. Important Considerations

1. When applying for a CB test certificate, note the following:  

(1) The application can be submitted to any "certifying/accrediting" NCB that covers the product scope.  

(2) The applicant can be either the manufacturer or an authorized entity representing the manufacturer.  

(3) Applications may include one or more factories producing products in one or more countries.  

(4) Applicants/manufacturers/factories located in countries without IECEE member institutions must pay an additional fee of 150 Swiss Francs for each CB test certificate to cover the operational costs of the system. This fee is collected by the NCB processing the application and deposited into the IECEE account.  

(5) Applicants can request NCBs to test products based on country-specific differences.  

2. Manufacturers seeking product certification for target markets must follow these procedures:  

(1) Submit an application to the NCB of the target country;  

(2) Provide the CB test certificate;  

(3) Provide the CB test report (which may include country differences);  

(4) Supply product samples if requested by the NCB of the target market. This is to verify that the product is consistent with the one initially tested by the issuing NCB and to cover country differences.  

3. Country Differences  

Country differences refer to variations between a country's standards or regulations and corresponding international standards. All country differences from CB system member countries are submitted to the IECEE secretariat and published in the CB Bulletin.
