The CB system (IEC system for conformity testing and certification of electrical products) is an international system operated by IECEE. The certification bodies of each member country of IECEE test the safety performance of electrical products on the basis of IEC standards. The test results are the CB test report and CB The test certificate is a system of mutual recognition among the member states of IECEE. The purpose is to reduce international trade barriers due to the need to meet the certification or approval criteria of different countries. IECEE is the abbreviation of the International Electrotechnical Commission's electrotechnical product conformity testing and certification organization.

The countries participating in the CB system come from designated agencies in 53 countries, including major industrialized countries, and are currently part of the CB certification process—it is considered to be a domestic part of many countries in the European Union (including those that have not yet become official member states) The basis of certification.

Member states

Up to now, 66 certification bodies in 51 countries and more than 270 CB laboratories under their jurisdiction have participated in this mutual appointment system. The member countries participating in the CB system include all major exporters of China's mechanical and electrical products.

Argentina, Austria, Australia, Belarus, Belgium, Brazil, Canada, China, Czech Republic, Germany, Denmark, Spain, Finland, France, United Kingdom, Greece, Hungary, India, Ireland, Israel, Italy, Japan, South Korea, Mexico, Netherlands, New Zealand, Norway, Poland, Portugal, Russia, Romania, Singapore, Slovakia, Slovenia, South Africa, Turkey, Ukraine, United States, Yugoslavia, Switzerland, Malaysia, Sweden, Thailand, UAE, Saudi Arabia, Pakistan, Bulgaria, Uruguay.

1. The manufacturer must obtain product certification for the target market including the following procedures:

Application submitted to the NCB of the target country;

CB test certificate;

CB test report (can include national differences);

Provide product samples to the target market when required by NCB.

The purpose of requesting samples is to verify that the product is consistent with the product originally tested by NCB and has covered national differences.

CB test certificate and CB test report

2. Matters needing attention:

CB certification is applicable in the member states of the CB system, covering developed countries and most developing countries around the world.

CB certification is only for sample testing.

If the foreign certification mark is converted, a factory inspection is required.

The CB certificate must be presented at the same time as the CB test report to be valid.

When applying for a CB certificate, the applicant should first explain to the CQC and CBTL the country/region to be exported, so that the certification body can help understand the country’s standard differences, arrange the difference experiment in time, and avoid the applicant from the foreign certification body/test Institutions will do additional experiments when applying, postpone the accreditation process and invest more costs.

The application for CB test certificate can be submitted by the applicant to any "certification/approval" NCB that covers the scope of the product.

The applicant can be either the manufacturer or an entity authorized to represent the manufacturer.

The application may include one or more factories producing products in one or more countries.

The applicant can request NCB to test the product according to the national difference of the country where the product is sold.

Q&A

Q1: The difference between accredited NCB and issuance / accredited NCB

The National Certification Body (NCB) is a certification body that issues nationally recognized certificates of conformity to electrical products.

Recognized NCB is an NCB that recognizes the CB test certificate and CB test report issued by other NCBs, and uses this as the basis for issuing its own national certificates and marks within a specific product field and standard range. It is recognized that NCB does not automatically have the power to issue CB test certificates.

Certification/recognition NCB

In addition to performing the functions of accrediting the NCB, the issuing NCB has the right to issue CB test certificates within the scope of its registered standards.

The certification/recognition NCB's scope of accreditation can be greater than its certification scope. The certification and accreditation scopes are published in the relevant "scope" area on the website.

CB laboratory (CBTL) is a laboratory accepted by the CB system. It tests one or more product categories and issues CB test reports under the responsibility of a specific NCB. The CB laboratory can be combined with different NCBs in the CB system, but when it cooperates with multiple NCBs, it can only cooperate with one NCB for testing a certain product category (for example, OFF).

Q2: Can CB certified products be directly affixed with the CE mark on the product?

The CE mark contains multiple directives, but when the product is only applicable to the Low Voltage Directive (LVD), the CB certification including EU differences proves that it has met the requirements of the CE mark, so companies can stick the CE mark on the product.

CB certification only covers safety requirements. Even if the CB certification includes EU differences, if the product is also covered by other EU directives (such as electromagnetic compatibility EMC, Machinery Directive, etc.), its CB certification cannot indicate that it has met the CE mark. The requirements can only indicate that the product has met the requirements of the Low Voltage Directive (LVD) of the CE mark. The CE mark cannot be affixed to the product, and relevant electromagnetic compatibility and EMC tests must be supplemented.
