How Does it Work?
A manufacturer applies to any of the participating NCBs for a CB Test Certificate. The NCB will perform complete testing and evaluation of the manufacturer's product to determine conformity with the appropriate standard accepted in the Scheme. If the product is found to be in compliance with the standard, the NCB will issue a CB Test Report and CB Test Certificate.

These documents may then be presented to other participating NCBs for those nations from which the manufacturer may need additional certifications. Upon evaluation of the test documents, the other NCBs may determine that the results are sufficient to grant national certification without performing additional tests. Thus, the CB Scheme offers the manufacturer an efficient way of having product investigated to the appropriate IEC standards and to the National Deviations of participating countries in which the product is intended for market.

A CB Test Report can also be used to support your self-declaration towards the CE Marking, which is mandatory in countries of the European Union.

What Standards are Accepted in the CB Scheme?
The standards used are the various internationally recognized IEC standards for electrical equipment. The CB Scheme, however, permits each country to have some National Deviations to address local safety concerns.

The United States and its NCBs currently participate in the CB Scheme for the following categories:

·  IEC 60065 - Household Electronic Equipment

·  IEC 61010 - Laboratory Equipment

·  IEC 60950 - Information Technology Equipment (ITE) and Office Equipment

·  IEC 60601 - Electro-medical Equipment

·  IEC 60335 - Household Electronic Equipment

How are National Deviations Handled?
Compliance with National Deviations may be evaluated by either the NCB issuing the CB Certificate and CB Test Report or by the NCB to whom the test documents are presented for recognition and acceptance.

It may help further reduce costs, completion time, sample requirements, and project complexity by having all appropriate National Deviations evaluated by the NCB who issues the CB Test Certificate and CB Test Report.
