CB system (IEC system for qualification testing and certification of electrical products) is an international system operated by IECEE. Certification bodies of IECEE member states conduct safety tests on electrical products based on IEC standards. The test results, namely CB test report and CB test certificate, are mutually recognized by all IECEE member states. The aim is to reduce barriers to international trade arising from having to meet certification or approval criteria in different countries. IECEE is the abbreviation of the International Electrotechnical Commission for Testing and Certification of Electrical Products.

Introduction to the

The development of

Initially, the CB system was initiated by CEE (formerly the European National Committee for Conformity Testing of Electrical Equipment) and incorporated into the IEC in 1985.

The IECEE CB system is the first truly international system for mutual recognition of safety test reports for electrical products. Multilateral agreements are formed between national certification bodies (NCB) of each country, and manufacturers can obtain national certification of other member countries of the CB system by means of a CB test certificate issued by NCB.

CB system is based on international IEC standard. If the national standards of some Member States are not fully consistent with the IEC standards, the existence of national differences is allowed, but should be disclosed to other Members. The CB system uses the CB test certificate to confirm that the product sample has successfully passed the appropriate tests and has complied with the relevant IEC requirements and the requirements of the Member State concerned.

The main goal of CB system is to promote international trade, which means by promoting the unification and coordination of national and international standards as well as the cooperation of product certification bodies, so that manufacturers are closer to the ideal goal of "one test, multiple application".

The term

IECEE stands for "The IEC System for Conformity Testing and Certification of Electrical Equipment" -- "International Electrotechnical Commission Electrical Products Conformity Testing and Certification". The official name of the CB system is "Scheme of the IECEE for Mutual Recognition of Test Certificates for Electrical Equipment" -- "IECEE Mutual Recognition System for Electrical Products". The short name of CB system means "Certification Bodies' Scheme".

Scope of system

The products covered by CB system are the products within the scope of IEC standards recognized by IECEE system. The new IEC standard is adopted by the CB system when three or more Member States declare that they want and support a standard to be included in the CB system. The IEC standards used are published in the CB Bulletin and on the IECEE website.

Electromagnetic compatibility (EMC) is not incorporated into the CB system unless specifically required by the IEC standard used. However, the CB system has begun to survey its members about their willingness to perform EMC measurements in conjunction with safety testing. The results of this survey will be published in the CB Bulletin on this topic.

Relevant institutions

National certification bodies (NCB) are the certification bodies that issue nationally recognized certificates of conformity to electrical products. To become a member of the CB system, NCB's internal quality systems and technical capabilities must meet specific requirements. An NCB can be classified as an accredited NCB or a certification/accreditation NCB according to its qualifications.

Recognition of NCB

An NCB recognizes CB test certificates and CB test reports issued by other NCB issuers as the basis for issuing its own national certificates and marks within a specific product area and standard.

Approved NCB does not automatically have the authority to issue CB test certificates.

Certification/recognition of NCB

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

Certifying/Accreditation An NCB may be accredited beyond the scope of its certification. Licensing and recognition scopes are posted on the website in the relevant "scopes" section.

A CB laboratory (CBTL) is a laboratory accepted by the CB system that performs tests and issues CB test reports for one or more product categories under the responsibility of a specific NCB. A CB laboratory can collaborate with different NCBs in a CB system, but when it collaborates with multiple NCBs, testing for a defined product class (for example, OFF) can only be done with one NCB.

The certificate report

A CB report is a standardized report that sets out the requirements of the relevant IEC standard in an item-by-item form. The report provides the results of all tests, measurements, validations, inspections and evaluations required, which should be clear and unambiguous. The report also includes photos, circuit diagrams, pictures, and product descriptions. According to the rules of the CB system, the CB test certificate is only valid if it is provided with the CB test report.

To apply for the certificate

When applying for a CB test certificate, the following points should be noted:

- An application for a CB test certificate may be submitted by the applicant to any "Certification/Accreditation" NCB covering the product range.

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

- The application may include one or more factories producing the product in one or more countries.

- Applicants/manufacturers/factories located in countries without IECEE member institutions are required to pay an additional fee of CHF 150 per CB test certificate to cover the operating costs of the system. This fee will be charged by the NCB which handles the CB test certificate application and will be credited to the IECEE account.

- The applicant may request the NCB to test the product for country differences in the country in which the product is sold.

To obtain product certification for the target market, the manufacturer includes the following procedures:

-Application submitted to the NCB of the target country;

- CB test certificate;

- CB test report (may include country differences);

- Provide product samples to target market when requested by NCB.

The purpose of requiring a sample is to confirm that the product is consistent with the product tested by the original NCB certification and that the country differences have been covered.

CB test certificate and CB test report

National differences

A national difference is the difference between a national standard and the corresponding international standard. The national differences of all countries that have joined the CB system are submitted to the IECEE secretariat and published in the CB Bulletin.

The structure of the organization

The CB system is managed by the certification management committee (CMC) and reports to the conformity assessment committee (CAB) of the International Electrotechnical Commission (IEC). CAB approves CMC's recommendations regarding changes to CB system principles, appointment of officers, finance, and IECEE policies. The responsibility of CMC is to operate, develop and improve the CB System according to the principles of the CB System, to decide on acceptance, rejection and suspension of membership, and to decide on new product categories and standards of the CB System.

The membership of the CMC is composed of representatives from member countries, including NCB representatives, CMC executives (chairman, vice-chairman, secretary and treasurer), the chairman and secretary of the Test Laboratory Committee (CTL), representatives of the IEC Advisory Committee (such as ACOS), the Safety Advisory Committee, and the IEC Secretary General.

The Test Laboratory Committee (CTL) is composed of representatives from the NCB and CB laboratories. The CTL handles the test procedures and interprets the technical requirements, test conditions, test equipment, and comparison tests. Its main objective is to enhance technical reliability and consistency, which is required for mutual recognition of test results within the CB system.
