The IECEE CB Scheme is the world's first truly international system for mutual acceptance of test reports and certificates dealing with the safety of electrical and electronic components, equipment and products. It is a multilateral agreement among participating countries and certification organizations. A manufacturer utilizing a CB test certificate issued by one of the accepted National Certification Bodies (NCBs) can obtain certification marks of the latter, within their scope of adherence, in the countries where the accepted NCBs are located.
The Scheme is essentially based on the use of international (IEC) Standards. If some members' national standards are not yet completely harmonized with IEC Standards, national differences, Special National Conditions (SNC) and Regulatory Requirements are permitted subject to formally declaring and detailing them to the IECEE Secretariat for further publication. The CB Scheme utilizes CB Test Certificates to attest that product samples have successfully passed the test conditions and are in compliance with the requirements of the relevant IEC Standard(s). When applicable, the CB Test Certificate and itĄŻs associated Test Report can also include declared national differences, Special National Conditions (SNC) and Regulatory Requirements of various member countries.
The main objective of the Scheme, is to facilitate trade by promoting harmonization of the national standards with international Standards and cooperation among accepted NCBs worldwide in order to bring product manufacturers a step closer to the ideal concept of "one product, one test, one mark, where applicable'.


Originally, this Scheme was operated by the CEE (former European "International Commission for
Conformity Testing of Electrical Equipment"). It was integrated into IEC in 1985.


The products covered by the CB Scheme are those within the scope of IEC Standards accepted in the IECEE System (see http://www.iecee.org/cbscheme/html/cbstand.htm). A new IEC Standard is adopted for use in the Scheme when at least three Member Bodies of the IECEE, or the NCBs which they represent, declare their recognition of CB Test Certificates. At least 1 of the NCBs shall be an Issuing and Recognizing NCB. A current list of IEC Standards used is provided in the CB Bulletin and the IECEE Website.


The Scheme is managed by a Certification Management Committee (CMC) reporting to the
Conformity Assessment Board (CAB) of the International Electrotechnical Commission (IEC)
seeking approval on changes to the Basic Rules, appointment of officers, finances, and policy of the IECEE. The role of the CMC is to manage, operate, develop, and promote the Scheme in accordance with its rules. To decide on acceptance, rejection or suspension of members, and to make decisions on new product categories and Standards to be accepted in the CB Scheme.
The membership of the CMC comprises the IECEE Officers, delegations from member countries including NCB representatives, CTL Chair and Secretary, representatives of IEC Advisory Committees such as ACOS, the Advisory Committee on Safety, and the General Secretary of the IEC.
The structure of the IECEE comprises a Board Of Appeals (BOA) composed by the Chairman and four members, including 4 alternates, all appointed by the CMC.
The Assessment Advisory Group (AAG) is also appointed by the CMC and deals with the overall process of the Peer Assessment Program, in addition to reaching common understanding of the requirements of ISO/IEC 17025 and ISO/IEC Guide 65.
One of the pillars of the IECEE is the Committee of Testing Laboratories (CTL) which consists of representatives from member NCBs and CBTLs. CTL deals with test procedures, common understanding and uniform application of technical requirements, test conditions, test equipment, and proficiency testing programs. Its main objective is to promote technical confidence and consistency required to facilitate acceptance of test results among the CB Scheme members. CTL publishes its common understandings, called Ą±CTL Decision SheetsĄ±, intended as normative requirements together with the IEC standards, to be implementedby all NCBs and CBTLs.


An NCB that wishes to become a member of the CB Scheme for specified Standards or would like to extend its scope to include additional Standards, is required to submit an Application through its national member body in IECEE. The IECEE Secretary reviews all such Applications, appoints
Assessment Teams and organizes on-site assessments of the NCBs to verify compliance against ISO/IEC Guide 65 and the IECEE Rules of Procedure and Operational Documents. The IECEE Peer Assessments also ensure that each member NCB has the technical capability, competence and experience to carry out the required tests against IEC Standards and produce Test Reports acceptable to all other NCBs.
Assessment Teams comprise experts from participating NCB and CBTLs. Their Assessment
Reports are made available to all CMC members for comments and yet studied in detail by the
CMC Assessment Advisory Group, a standing committee of experienced IECEE experts. The
Assessment Advisory Group's objective is a consistent and efficient operation of the peer
assessment process. The acceptance of the assessment reports is decided by the CMC on the
recommendations of the Assessment Advisory Group.
A very similar process is followed for a CBTL except that they are assessed against ISO/IEC
17025 and the Application is endorsed by the rersponsible NCB prior to the submission of an
application to the IECEE Secretariat through the national Member Body of such NCB.
A CBTL may be associated with only one NCB per product category/standard.


The rules and procedures of the CB Scheme are published in the following IEC Publications:
IECEE 01 (Basic Rules of the IECEE);
IECEE 02 (Rules of Procedures of the CB Scheme); and

IECEE 01 describes the organization of the IECEE, its membership, the Certification Management Committee (CMC), Committee of Testing Laboratories (CTL), Board of Appeal, the roles and responsibilities of the committees and their officers, and the overall governance of the IECEE.
IECEE 02 describes the functioning of the CB Scheme, procedures an criteria for the acceptance and expansion of the scope of NCBs and CBTLs, procedures for issuing and handling of CB test certificates.
Detailed procedures for the operations of the Schemes are provided in the various Operational
Documents as listed in the relevant Annexes of the Rules of Procedures IECEE 02.

The CB bulletins provide the essential information of the CB Scheme and represent the key
instrument for the users of the CB Scheme. The IECEE Secretariat publishes the CB Bulletins at regular intervals. The Bulletins contains the following information:
- Standards accepted for use in the Scheme.
- Statistics on CB Test Certificates issued in the previous year.
- Information on participating NCBs including product categories and Standards for which they
have been recognized.
- National Differences of each member country for each Standard.
- Names and addresses of suppliers of test equipment for IEC Standards.
- Any other useful information pertaining to the operation of the IECEE.
