The CB Scheme applies to electrical and electronic equipment covered by IEC standards. The following categories are covered:

• Batteries
• Cables and Cords
• Capacitors as components
• Switches for appliances and automatic controls for electrical household appliances
• Electromagnetic Compatibility
• Household equipment and similar equipment
• Installation accessories and connection devices
• Luminaries
• Measuring, Control and Laboratory equipment
• Electrical equipment for medical use
• IT and office equipment
• Low voltage and high power switching equipment
• Installation protective equipment
• Photovoltaics
• Safety transformers and similar equipment
• Portable tools
• Electric Toys
• Electronics, entertainment
  

In the early days of the CB Scheme, only applicants manufacturing their products in a CB member country were accepted. Moreover, a manufacturer had to apply with the NCB of his own country. Today manufacturers from a non-member country can also apply for a CB Certificate with any NCB (not only to the NCB of their own country, but anywhere in the world) and the manufacturer may be represented by an applicant who acts on behalf of the manufacturer.
An application may cover one or more factories in one or more countries where the product is manufactured.

If a product is modified after the CB Test Certificate was issued, an appendix to the test report will be drafted instead of a new complete test report. This appendix contains those pages of the test report, which are relevant for the modified equipment. The CB Test Certificate will be re-issued with this additional test report.

Manufacturing equipment for export, you can save time and expenses by not having to go through the process of conformity testing for each national market again and again. Generally the product needs to be tested only once against international standards in order to obtain the necessary national certification in various countries.

Your equipment will be included in the "List of CB Test Certificates", where new certificates are published each year as a guide for wholesalers who can procure equipment conforming to integral international safety standards from manufacturers in many countries in the world.

If additional procedures are necessary to comply with national differences, the user of this scheme can save time by applying for additional tests that cover only the national deviations from the relevant international safety standards. If the manufacturer knows to which countries he wants to export his product, this can even be done at the first testing. All CB testing laboratories have information available on national conditions in the various countries.

TÜV Rheinland (Cologne) was accepted as a National Certification Body (NCB) in 1994, TÜV Rheinland of North America became an NCB in 1996 and TÜV Rheinland Japan followed in 1998. Afterwards, our Brazil, Hungary branches and LGA QualiTest GmbH also became NCB. Our Testing Laboratories are "accredited" as CB testing laboratories (CBTL). Since then, we issue thousands of CB Test Certificates & CB Test Reports for various products each year.
