The CB system (IEC system for the qualification testing and certification of electrical products) is an international system operated by IECEE. The certification bodies of IECEE member states test the safety performance of electrical products based on the IEC standard. The test results are the CB test report and CB. The test certificate is mutually recognized in the IECEE member states. The purpose is to reduce the barriers to international trade that arise from having to meet different national certification or approval criteria. IECEE is the International Electrotechnical Commission

Abbreviation for the organization of qualification testing and certification of electrical products.

history

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

the term

IECEE stands for "The IEC System for Conformity Testing and Certification of Electrical Equipment"-"International Electrotechnical Commission Conformity Testing and Certification Organization". 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 Product Test Certificates". The abbreviated name of the CB system means "Certification Bodies’ Scheme "-" Certification Bodies' Scheme ".

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

Accredited NCB

An NCB recognizes CB test certificates and CB test reports issued by other issuing NCBs, and uses this as the basis for issuing its own national certificates and marks within specific product areas and standards.

The accredited NCB does not automatically have the authority to issue a CB test certificate.

Certification / Recognition NCB

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

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

The 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, the test for a certain product category (such as OFF) can only be performed in cooperation with one NCB.

The scope of the CB system

The products covered by the CB system are products within the scope of the IEC standards recognized by the IECEE system. When more than three member states announce that they want and support a certain standard to join the CB system, the new IEC standard will be adopted by the CB system. The currently used IEC standards are published on the CB Gazette and the IECEE website.

At present, electromagnetic compatibility (EMC) is not included in the CB system, unless the IEC standard used specifically requires it. However, the CB system has begun to investigate with its members their willingness to take EMC measurements in conjunction with safety testing. The results of this survey will be published in the CB bulletin on this subject.

Apply for CB certificate

Regarding the application of CB test certificate, the following points should be noted:

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

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

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

-Applicants / manufacturers / factories located in countries without an IECEE member institution need to pay an additional fee of 150 Swiss francs per CB test certificate to compensate for the operating costs of the system. This fee is charged by the NCB that accepts the CB test certificate application and will be credited to the IECEE account.

-Applicants may require NCB to test products based on national differences in the country where the product is sold.

A manufacturer's product certification for the target market includes the following procedures:

-Applications to the NCB of the target country;

-CB test certificate;

-CB test report (can include national differences);

-Provide product samples to target markets as required by NCB.

The purpose of the sample is to confirm that the product is consistent with the original NCB tested product and has covered national differences.

CB test certificate and CB test report

The CB test certificate is a formal CB system document issued by an authorized NCB. The purpose is to inform other NCBs that the tested product samples are found to meet current requirements. The CB test certificate should not be used for advertising, but it is allowed to use the existing CB certificate as a reference.

A CB report is a standardized report that lists the requirements of relevant IEC standards in a list-by-list form. The report provides the results of all required tests, measurements, verifications, inspections and evaluations, which should be clear and unambiguous. The report also contains photos, circuit diagrams, pictures, and product descriptions. According to the rules of the CB system, the CB test report is only valid when provided with the CB test certificate.

If an NCB has the necessary test equipment and technical capabilities, it can test and evaluate products based on national differences in other countries. These additional tests are attached to the CB test report as an attachment and are usually endorsed by other accredited NCBs.

National differences

National differences are the differences between a country's standards and the corresponding international standards. The national differences of all countries joining the CB system are submitted to the IECEE Secretariat and published in the CB Gazette.

The organizational structure of the CB system

The CB system is managed by the Certification Management Committee (CMC) and reports to the Conformity Assessment Board (CAB) of the International Electrotechnical Commission (IEC). The CAB approves the CMC's recommendations regarding changes to the CB system principles, official appointments, finances, and IECEE policies. The responsibility of CMC is to operate, develop and improve the CB system in accordance with the principles of the CB system, determine acceptance, rejection and termination of membership, and determine new product categories and standards for the CB system.

CMC members are composed of representatives from member countries, including NCB representatives, CMC executives (Chairman, Vice-Chairman, Secretary and Treasurer), Test Lab Committee (CTL) Chairman and Secretary, IEC Advisory Committee (such as ACOS), Security Advisor Representative of the committee, Secretary General of the IEC.

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

Rules and procedures

The rules and procedures of the CB system are published in the following IEC publications:

IECEE 01 (Basic rules and procedures of IECEE)

IECEE 02 (CB system rules and procedures)

IECEE 01 describes the organization, membership, certification management committee (CMC), test laboratory committee (CTL), appeal committee, functions and responsibilities of these committees and their officials, and the overall management of IECEE.

IECEE 02 describes the role of the CB system, the criteria for recognizing and expanding the scope of NCB and CB laboratories, the procedures for issuing and processing CB test certificates, and the requirements for using manufacturers' test facilities.

CB Gazette

The CB Gazette provides basic information about the CB system and is the main tool for users of the CB system. The IECEE Secretariat regularly issues CB bulletins. The bulletin contains the following information:

-Standards used in the CB system;

-Statistics of CB test certificates issued in the previous year;

-Member NCB information, including product categories and standards for which they issue / recognize CB certificates;

-National differences for each standard in each member country;

-The name and address of the test equipment supplier required by the IEC standard.

Some information previously published in the CB Gazette is now available on the CB System website (www.iecee.org).

Benefits of the CB system to manufacturers

The CB system can bring benefits to manufacturers who export products to CB system member countries.

These manufacturers can:

-Select a suitable NCB for cooperation;

-All product testing is done by the same NCB, including testing for differences in target market countries;

-Use CB test report and certificate issued by NCB, and get national certification of other countries through NCB of other countries.

Although countries that recognize CB certificates will require manufacturers to submit applications, and may also require samples, they usually do not require additional testing or only a small number of tests, and the application process is mostly management work. Therefore, these CB test certificate and CB test report-based certification applications will be given priority over other certification applications, and reduce the application cycle and application costs.

Member States of the current CB system (43 in total)

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, USA, Yugoslavia, Switzerland, Malaysia, Sweden, Thailand

Since the reform and opening up, China has begun to implement a socialist market economy, and both the domestic market and international trade have developed rapidly. Many export enterprises in China, because they do not understand the requirements of various countries' certification systems, many export products cannot enter the international market, and the prices are far lower than the similar products in their countries. Therefore, these enterprises have to spend very precious foreign exchange every year, apply for foreign certification and issue inspection reports by foreign inspection agencies. In order to meet the needs of international trade, the country has gradually implemented an internationally accepted certification system. On May 7, 1991, the State Council promulgated the Regulations on Product Quality Certification of the People's Republic of China, and the State Technical Supervision Bureau also issued some rules to implement the Regulations to ensure that the certification process is carried out in an orderly manner. Since its establishment in 1954, the China Electrotechnical Product Certification Commission has been working to obtain international mutual recognition in order to serve the export of electrical products. In June 1991, the China Electrotechnical Product Certification Commission was awarded the International Electrotechnical Commission's Electrical Product Safety Certification Organization (iEcEE). The Management Board (Mc) is accepted as a national certification body that recognizes and issues CB certificates. Nine subordinate testing stations are accepted as CB laboratories (certification agency laboratories). As long as the company has obtained the cB certificate and test report issued by the committee, 30 member states in the IECEE one ccB system will recognize it. Basically eliminating the need to send samples to the importing country for testing, which saves costs and time to obtain the country's certification certificate, which is extremely beneficial to export products.

What is a CB test certificate

This certificate was developed by the International Electrotechnical Commission's Committee for Certification of Electrical Product Safety Certification (IEcEE) certification bodies (CCB). It is issued by a certification and accredited national certification body (see the figure below) and used with the attached test report To notify other national certification bodies that one or more samples of an electrical product have been tested in accordance with a standard adopted by the CEE, and prove that this sample (s) meet the standard. The cB test certificate is valid only when the relevant test report is attached. The test report should include the test results according to the relevant standards, and when required, the test results should also include the test results according to the stated national differences. At present, the product catalog of IecEnCB system certification is shown in Table 1. The cB test certificate must not be used in any form of advertising or promotional activities, but the holder of the CB test certificate can mention in the business communication that the CB test certificate has the product. As of July 1992, there were 30 members of the cB system. They are Austria (AT), Australia (AU), Belgium (BE), Canada (C ＾), Switzerland (CII). China (C, Sichuan, former Czech Slodek (Cs), Germany (DE), Denmark (DK), Spain (Es), Finland (Fi), France (FU, UK (oI3), Greece (GR), Hungary (NU, Ireland (IE), Israel (it), India (IN), Iceland (is), Italy (r), Japan (SV), South Korea (KR), Netherlands (NT), Norway (No), Poland ( PL), Sweden (sD, Singapore (SG), former Soviet Union (schuan, former Yugoslavia (YU), United States (Us)). These 30 member states should declare when they apply to join IECEE-CCB as a member of the cB system Recognize those IEC standards adopted by 1ECEE (see Table 2), and state that for the national differences (if any) in the approved standards, the differences currently described by countries are classified into two types: the difference from the national standard of the country '; Group differences are indicated by "C '; no differences are indicated by" r'. "(See Table 3). The specific differences between national declarations and corresponding IEC standards are shown in Chapter 4. If the following situations occur, the national certification body that issued the certificate CB test certificate can be revoked: abuse certificate one by one --- The certificate was issued incorrectly--the product no longer matches the sample tested and stated in the test report,-the certificate holder requested the revocation. When a CB test certificate has been revoked, the national certification of the certification is issued The agency must notify the CCB secretary as soon as possible and explain the reasons for the revocation. The CCB secretary must notify the manufacturer and all the certification bodies of all countries participating in the CB system regarding the relevant standards, and explain the reasons for the revocation. Each relevant national certification body can decide whether to withdraw the national certification or accreditation made on the basis of the CB test certificate.

Why apply for a CB test certificate

The company that obtained the cB test certificate is conducive to the export of electrical products used in homes, offices, workshops and similar places. "It is directly related to personal safety. Such products are subject to compulsory certification in some countries. After that, they are allowed to export to the country and sell on the market in that country. Even in countries that have not implemented compulsory certification, consumers are willing to purchase certified products with certification marks for their own safety. Therefore Large department stores also only sell certified products, which are also higher in price than certified products. Just as the power tools sold to Hong Kong businessmen in China, they have a higher CB certificated product than an uncertified product. The price is $ 2 each more. Certified products can protect users' personal safety. They are easy to sell and the price is relatively high. In addition, companies selling uncertified products also bear the risk of compensation for losses. Businesses have the responsibility to compensate consumers for their personal or property damage. The occurrence of such an accident will bring China to the international market. Bad consequences, such products will find it difficult to find customers in international trade. Therefore, not only is it economically lost, but it also loses its credibility. How to obtain the certification certificate of the importing country, there are two procedures to obtain the certificate: The first procedure is that the product has obtained the CB test certificate. Use the certificate with the CB test report to apply for the certification certificate of the country to the importing country; the second procedure is that the product does not obtain the CB test certificate and applies directly to the importing country for the country's For the certificate of conformity, if the second procedure is adopted, the applicant must first send the samples to the testing laboratory designated by the country according to the number of samples specified by the national certification body of the importing country, and pay the test fee. After that, the national certification body of the country sends an inspector or entrusts our testing station to review the quality assurance ability of the applicant enterprise. After passing the examination, the country's certification certificate can be obtained, using their logo, if the first type is used Procedure, the applicant only needs to submit the CB test certificate and CB test report (well attached The test results of the difference items) are sent to the national certification body of the country. The test results can be recognized without sending samples or just individual samples for review. Finally, the national certification body of the country passes the factory's quality assurance ability review and passes. Obtain a certificate of conformity and use the logo of the certification body of the country. Comparing the two procedures, we can understand that the first procedure is simpler and cheaper than the second procedure. Chinese enterprises have obtained Chinese electrical products After the CB test certificate issued by the certification committee, apply to the CB system member countries for the certification of the country's national certification body; it is economical and time-saving.

The procedure for applying for a CB test certificate from CCEE is as follows

(1) The applicant is the holder of the CB test certificate The applicant can be a business or an agent of the business. In the latter case, you must submit certification documents authorizing the applicant to handle the application on behalf of the enterprise, and provide certification documents that the enterprise bears the same responsibilities as the applicant. These responsibilities refer to compliance with the rules and procedures of the ECEE, CCEE charter, certification rules and procedures, and relevant national laws of China. Regulations and rules. 2. The application may include one or more manufacturing plants in the applicant's country, and the products manufactured by these manufacturing plants will be controlled by the enterprise. 3． When manufacturing the same product in different countries, the applicant should submit a separate application for the enterprise he represents in each country. 4． If the applicant is in a non-member state of CCB and is applying for a business agent of a non-member state, a surcharge must be paid for each application. The amount of surcharge is determined by the management committee of IECEE. Unless otherwise agreed, the surcharge shall be collected by the CCEE processing the application and remitted to the IECEE Secretariat and deposited into the account of the CB system. Note: Solely-owned enterprises are treated as foreign enterprises, and joint ventures are treated as domestic enterprises.

(2) Preparatory work before application-When an applicant with the status of a legal person intends to sell its products to the world market, it must comply with the IEC standards adopted in the CB system during the product development and design stage (see Table 1). At the same time, the differences between the national standards of the CCB member states and the 1EC standards must also be considered. Before the applicant submits the application and samples, it is necessary to confirm that the products meet the IEC safety standards and the relevant national standards of the exporting country. A person in the organization is responsible for processing the application for the cB test certificate, sending samples, obtaining the certificate, and related matters after obtaining the certificate, and making them understand the CB procedure.

(3) Application Procedures After completing the preparations for the application, the applicant contacted the CCEE Secretariat to obtain a CB test certificate application printed by CCB (see Figure 2). The letter states the applicant's name, address, national registration number (enterprise business license number), telephone, fax, and product name, model, specifications and trademark to be applied for.

2. After receiving the letter from the enterprise, the CCEE Secretariat will send the application form, application procedures and fee requirements to the applicant.

3． After receiving the cB application and related materials sent by the CCEE Secretariat, the applicant should complete the application (typed in English) according to the requirements of the application and submit it to the CCEE Secretariat in quadruplicate (one original and three copies) as the official To apply, the applicant keeps a copy of the file and pays the required fees at the same time.

4． If the applicant needs CCEE to prove that its products meet the differences between the national standards of China or other countries and the corresponding LC standards, then when submitting the application, an application for a test report including these differences may be submitted. The applicant and Additional test fees shall be paid, which shall be in accordance with the relevant provisions of the charging standards.

5． The ccEE Secretariat receives the application submitted by the applicant (! sent the notice and the fee, and sends a notification to the applicant within two weeks, and issues a cB test task notice to the cB laboratory (according to the division of labor in the cB laboratory, or The testing laboratory that agreed to take on the task with the relevant agency is the testing station).

6. After receiving the notification, the applicant will send samples to the designated CB laboratory according to the notification requirements.

(4) If the test results of the cB test certificate are qualified, the ccEE will issue the cB test certificate to the applicant and attach the original CB test report. If the application contains a difference test, an additional test report will be attached.
