CB certification of solar street light
The IECEE CB system is the first truly international system for mutual recognition of electrical product safety test reports. The national certification bodies (NCB) of various countries have formed a multilateral agreement, and manufacturers can obtain the national certification of other member states of the CB system by virtue of a CB test certificate issued by the NCB.
The CB system is based on the 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 also allowed, but it should be announced to other members. The CB system uses the CB test certificate to verify that the product samples have successfully passed the appropriate tests and comply with the relevant IEC requirements and the requirements of the relevant member states.
The main goal of the CB system is to promote international trade, and its means are to bring manufacturers closer to the ideal “one test, multiple applications” goal by promoting the harmonization of national and international standards and the cooperation of product certification agencies.
Initially, the CB system was initiated by CEE (the former European “National Committee for Qualification Testing of Electrical Equipment”) and merged into IEC in 1985. IECEE stands for “The IEC System for Conformity Testing and Certification of Electrical Equipment”-“International Electrotechnical Commission” Electrical products 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 of Test Certificates for Electrical Products”. 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 into a recognized NCB or a certification/recognized NCB according to its qualifications.
An NCB recognizes the 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 the scope of specific product areas and standards.
It is recognized that NCB does not automatically have the power to issue CB test certificates.
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 on the website. The relevant 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).
The products covered by the CB system are products within the scope of the IEC standard recognized by the IECEE system. When more than three member states announce that they hope and support a certain standard to join the CB system, the new IEC standard will be adopted by the CB system. The IEC standards currently in use are published on the CB Bulletin 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 its members’ willingness to conduct EMC measurements together with safety testing. The results of this survey will be published in the CB Bulletin on this subject.
1. Regarding the application for CB test certificate, the following points should be noted:
1) The application for CB test certificate can be submitted by the applicant to any “certification/approval” NCB that covers the scope of the product.
2) The applicant can be either the manufacturer or an entity authorized to represent the manufacturer.
3) The application may include one or more factories producing products in one or more countries.
4) Applicants/manufacturers/factories located in countries without IECEE member institutions need to pay an additional fee of 150 Swiss francs for each CB test certificate to compensate for the operating cost of the system. This fee is collected by the NCB that accepts the CB test certificate application and will be credited to the IECEE account.
5) The applicant can request NCB to test the product according to the national difference of the country where the product is sold.
1) Application submitted to the NCB of the target country;
2) CB test certificate;
3) CB test report (can include national differences);
4) 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.
The CB test certificate is a formal CB system document issued by the authorized NCB, and its purpose is to inform other NCBs that the tested product samples are found to meet the current requirements. The CB test certificate should not be used for advertising, but it is allowed to use the existing CB certificate as reference material.
The CB report is a standardized report, which enumerates the requirements of the relevant IEC standards in the form of an item-by-item list. The report provides the results of all required tests, measurements, verifications, inspections, and evaluations. These results 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 it is provided with the CB test certificate. If an NCB has the necessary testing 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 recognized by other recognized NCBs.
National difference is the difference between a country’s standard and the corresponding international standard. All national differences of countries joining the CB system are submitted to the IECEE Secretariat and published in the CB Bulletin.
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). CAB approved CMC’s recommendations on changing the principles of the CB system, appointment of officials, finance 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, decide to accept, reject and suspend membership, and determine the new product categories and standards of the CB system.
The members of CMC are composed of representatives from member states, including NCB representatives, CMC executives (chairman, vice-chairman, secretary and treasurer), the chairman and secretary of the Test Laboratory Committee (CTL), IEC advisory committees (such as ACOS), and safety consultants Representative of the committee, Secretary-General of IEC.
The Committee of Testing Laboratories (CTL) is composed of representatives from NCB and CB laboratories. CTL is responsible for handling test procedures and explaining technical requirements, test conditions, test equipment and comparison tests. Its main goal is to enhance technical credibility and consistency, which are the rules and procedures required for mutual recognition of test results in the CB system. 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 (rules and procedures of the CB system)
IECEE 01 describes the organization, membership, certification management committee (CMC), testing laboratory committee (CTL), appeal committee, the 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 recognition of the standards of NCB and CB laboratories and the basis for expanding their scope, the procedures for issuing and processing CB test certificates, and the requirements for using the manufacturer’s test facilities.
The CB Bulletin provides basic information about the CB system and is also the main tool for users of the CB system. The IECEE Secretariat regularly publishes CB bulletins. The bulletin contains the following information:
1) Standards used in the CB system;
2) Statistics of CB test certificates issued in the previous year;
3) Information about the member NCB, including the product category and standard of the CB certificate issued/recognized by them;
4) The national differences of each standard in each member country;
5) The name and address of the test equipment supplier required by the IEC standard.
6) Some information previously published in the CB Bulletin is now available on the website of the CB system (www.iecee.org).
The CB system can bring benefits to manufacturers who export their products to member states of the CB system.
These manufacturers can:
-Choose a suitable NCB for cooperation;
-All product tests are done by the same NCB, including tests for differences in target market countries;
-Use the CB test report and certificate issued by NCB, and obtain the national certification of other countries through the member NCB of other countries. Although the country that recognizes the CB certificate requires the manufacturer to submit an application, and may also require the submission of samples, there is usually no need for additional testing or only a small amount of testing. Most of the application processing process is some management work. Therefore, these certification applications based on CB test certificates and CB test reports will be processed prior to other certification applications, and the application cycle and application fees will be reduced.
