The CB system (the IEC system for testing and certification of electrical products) is an international system IECEE operates. The certification bodies of member States test the safety performance of electrical products on the basis of IEC standards. The test results are a system in which CB test reports and CB test certificates are mutually recognized in each member State. The aim is to reduce barriers to international trade arising from the need to meet different national certification or approval criteria. IECEE is the International Electrotechnical Commission electrical products qualified testing and certification organization abbreviation.

Introduction of CB
CB( Certification Authority) The process is based on an international agreement IECEE" the world system of conformity testing and certification of electrical products. It is the agreement between the national certification bodies within the system, dedicated to the mutual recognition of the results of electrical products audit.

Countries participating in the CB system come from designated agencies in 53 countries, including major industrialized countries, all under the CB accreditation process – which is considered to be the basis for domestic certification in many countries within the EU, including those that have not yet become full members. CB certification is for sample testing only. if the factory inspection is required when converting the foreign certification mark.

Application for CB should pay attention to the problem

CB certificate must be produced with the CB test report to be valid. When applying for a CB certificate, the applicant should pay attention to informing the CQC and the CBTL of the country/region to be exported first, so that the certification body can help to understand the standard differences in the country, arrange the difference experiment in time, avoid the applicant to apply to the foreign certification body/testing institution to make up the experiment, delay the approval process and invest more fees. CB accreditation is applicable in member countries of the CB system, covering both developed and most developing countries globally. CE logo applies to 28 European countries such as the European Union. CB certification only covers safety requirements, even if CB certification contains eu differences, if the product is also covered by other eu directives (e.g. emc EMC、 mechanical directives, etc.), its CB certification can not indicate compliance with the requirements of the CE logo, can only indicate that the product has met the requirements of the low voltage instruction (LVD) of the product logo, can not paste the CE logo on the product, must supplement the relevant emc EMC and other tests. CE logo contains more than one instruction, but when the product is only applicable to low voltage instruction (LVD), the CB certification eu differences proves that it meets the requirements of the CE logo, so the enterprise can paste the CE logo on the product.
★ A total of 66 accreditation bodies from 51 countries and more than 270 CB laboratories affiliated with them participate in the system. 
★ Among the member countries participating in the CB system are all major exporters of Chinese electromechanical products.
