▍What is CB Certification？
IECEE CB is the first genuine international system for mutual recognition of electrical equipment safety test reports. NCB (National Certification Body) reaches a multilateral agreement, which enables manufacturers to obtain national certification from other member countries under CB scheme on the basis of transferring one of the NCB certificates.
CB certificate is a formal CB scheme document issued by authorized NCB, which is to inform other NCB that the tested product samples conform to present standard requirement.
As a kind of standardized report, CB report lists relevant requirements from IEC standard item by item. CB report not only provides results of all required testing, measurement, verification, inspection and assessment with clearness and non-ambiguity, but also including photos, circuit diagram, pictures and product description. According to the rule of CB scheme, CB report will not take effect until it presents with CB certificate together.
▍Why we need CB Certification?
- Directly recognized or approved by member countries
With CB certificate and CB test report, your products can be exported to some countries directly.
- Convert to other countries certificates
The CB certificate can be directly converted to the certificate of its member countries, by providing the CB certificate, test report and difference test report (when applicable) without repeating the test, which can shorten the lead time of certification.
- Ensure the Safety of Product
The CB certification test considers the product’s reasonable use and foreseeable safety when misused. The certified product proves the satisfactory of the safety requirements.

Chinese National mandatory standard GB 4943.1-2022, Audio/video, information and communication technology equipment Part 1: Security requirements, was released on July 19. The standard refers to the international standard IEC 62368-1:2018, there are two main outstanding improvements: on the one hand, the scope of application is further expanded, the new version of the standard integrates the original mandatory national standards GB 4943.1-2011 Information Technology Equipment Security Part 1: General Requirements and GB 8898-2011 Audio, Video and Similar Electronic Equipment Security Requirements, covering all products of audio, video, information and communication technology equipment; on the other hand, there are technically optimizing and upgrade. The new version of the standard raises the concept of safety engineering, proposes energy classification, and takes consideration of following six types of sources of danger: injury caused by electricity, fire caused by electricity, injury caused by harmful substances, injury caused by machinery, thermal burns, sound and light radiation, and put forward the corresponding safety requirements and test methods.
The application scope of two standards is different. The scope of new GB 4943 national standard will combined the previous version of GB 4943.1-2011 and GB 8898-2011, covering three categories of equipment, audio and video equipment, information technology equipment, communications technology equipment, which we often say “electronic products”.
