Electrical or electronic equipment carrying the CB symbol shows that it has been tested and complies with IEC International Standards. Once a manufacturer has obtained a CB Test Report and CB Test Certificate they can submit the results to a National Certification Body (NCB) - such as BSI - within the IECEE member country where they wish to trade.
In turn, the NCB tests for compliance with relevant national safety standards. However, with CB certification in place, there is often little need for additional testing, enabling the NCB to authorise permission to trade almost immediately.
This practice simplifies and speeds up market entry for manufacturers, whilst also saving them time and money spent obtaining country-specific safety certification.
It also assures key stakeholders, from end-customers to government organizations, as to the safety and reliability of a final product.
