What is a CB Test Certificate?

cb certification is an international system. Typically, a CB certificate and CB test report are used together, but many clients often confuse these two concepts. Below, we’ll explore the contents and benefits of CB test reports with insights from China’s JJR Laboratory.

CB Test Report

A CB test report is a standardized document that lists the requirements of relevant IEC standards in a checklist format. It includes the results of all tests, measurements, verifications, inspections, and evaluations required, presented in a clear and unambiguous manner. The report also contains photographs, circuit diagrams, images, and a description of the product.

The CB certificate, on the other hand, is an official CB system document issued by an authorized NCB (National Certification Body). Its purpose is to inform other NCBs that the tested product samples comply with current requirements. Note that the CB certificate should not be used for advertising purposes but may be referenced in documentation.

Benefits of CB Test Certificates/Reports

1. Conversion to Foreign Certification Certificates 

If you have obtained a CB test certificate and CB test report, you can directly apply for certification in other countries. Certification bodies in the target countries will review the CB test certificate and report (including reports on national deviations). If the review is satisfactory, you can obtain the country's certification without undergoing additional testing based on the target country’s regulations.

2. Conversion to Chinese National Certification Certificates 

CB test reports, supplemented with reports on deviations, can be used to issue Chinese national product certification reports. This enables you to obtain China’s mandatory or voluntary electrical product certifications.

3. Direct Recognition or Approval by Other Countries 

With a CB test certificate and CB test report, your products can be exported directly to certain countries without additional certification.

4. Cost and Time Savings 

Domestic companies applying for CB test certificates through domestic CB testing laboratories can save on costs and reduce sample and document processing time. This allows companies to obtain CB certificates more quickly.

5. Increased Likelihood of Passing Product Testing 

If a company has already obtained a CB test certificate, most or all CB test results will be recognized when applying for certification in other countries. This can eliminate or reduce the need for resubmission of samples for testing, saving time and expenses. Moreover, conducting CB tests domestically beforehand increases the chances of passing national deviation tests.

Introduction to CB Certification

The CB system (IECEE System for Conformity Testing and Certification of Electrical Equipment) is an international system operated by the IECEE. Member certification bodies of the IECEE test the safety performance of electrical products based on IEC standards. The results, namely the CB test report and CB test certificate, are mutually recognized among member countries. This system aims to reduce international trade barriers caused by the need to meet diverse certification or approval criteria across countries.

The IECEE stands for “The IEC System for Conformity Testing and Certification of Electrical Equipment” – the International Electrotechnical Commission System for Conformity Testing and Certification of Electrical Equipment.
