Guide to US Authorisations

Electrical equipment marketed in the USA requires authorization. There are three levels of evidence required according to the risk of interference that the type of equipment possesses.

Level 1: Verification

Low risk should be "Verified". I.e. TVs, radios and most digital devices with low probability of causing interference. The equipment is tested at any facility of the manufactures choice and details kept on file should they ever be requested for inspection.

Level 2: Declaration of Conformity

Medium risk requires a "Declaration of Conformity". I.e. CB radios, digi-boxes, PCs and other digital devices considered to be medium risk. The product is tested at an accredited facility and similar to in Europe the manufacture draws up a Declaration to accompany the product and its technical file.

Level 3: Certification

High risk requires "Certification". I.e. RF transmitters and certain other high risk devices. The product is tested at a listed facility and the technical file reviewed by an independent body before a certificate is granted and details listed on the FCC website.
