The CB Scheme is a standardized system of the International Electrotechnical Commission (IEC) for the testing and certification of electrical equipment.

The IECEE CB scheme is a multilateral agreement between member countries and their national certification organizations. IECEE is based on the principles of mutual recognition by its global members and promotes the harmonization of national standards with the international standards developed by the IEC. The IECEE scheme covers more than 50 countries. The list of IECEE members can be founded via the link:


The manufacturer, using a CB certificate issued by one of the approved national certification bodies, can subsequently obtain certificates in other countries, within the scope of their application by contacting the national certification authority of another country.

The scheme is based on the use of international IEC standards and uses CB certificates to confirm that product samples have successfully passed the tests and met the requirements of the IEC standards. If necessary, the CB certificate and test report may include declared national differences, special national conditions and regulatory requirements of the member countries of the IEC.

There are 23 categories of electrical equipment and testing services covered by IECEE:

  • Batteries;

  • Cables and cords;

  • Capacitors as components;

  • Switches for appliances and automatic controls for electrical household appliances;

  • Electrical energy efficiency;

  • Electrical vehicles;

  • Electromagnetic compatibility;

  • Household and similar equipment;

  • Hazardous substances testing service;

  • Industrial automation;

  • Installation accessories and connecting devices;

  • Luminaires;

  • Measuring equipment;

  • Electrical equipment for medical use;

  • Miscellaneous;

  • IT and office equipment;

  • Low voltage, high power switching equipment;

  • Installation protective equipment;

  • Photovoltaics;

  • Safety transformers and similar equipment;

  • Portable tools;

  • Electric toys;

  • Electronics, entertainment.

An application for a CB Test Certificate and associated Test Report can be made to any IECEE National Certification Body. The test laboratory of the NCB will carry out the relevant tests based on the applicable IEC International Standards and issue a Test Report. After receiving the CB certificate, the procedure for obtaining product certification for the target market includes:

  • Filing an application with National Certification Body in the target market;

  • Providing the CB test certificate;

  • Providing the CB test report, including annexes with national differences, if applicable;

  • Provision of the product samples on the National Certification Body’s request.

CB scheme eliminates the need for multiple testings and reduces the obstacles to international trade, because the manufacturer will not need to meet different regulations, national certifications or approval criteria.

The main objective of the CB scheme is to facilitate trade by facilitating the harmonization of national standards with international ones; enhancing cooperation among certification bodies around the world; approach of the manufacturer to the ideal concept "one product, one test, one certificate".


Thus, covering all IECEE product categories and equipped with a global network of testing laboratories qualified to test electrical and electronic products to a range of IEC standards, makes CB scheme an ideal option to support the compliance with the IEC standards list and facilitate access to markets around the world.
