Class B certification

Class B certification
   An FCC certification for computer equipment, including PCs, laptops, and portables destined for use in the home rather than in a commercial setting. Class B levels of radio frequency interference (RFI) must be low enough so that they do not interfere with radio or television reception when there is more than one wall and 30 feet separating the computer from the receiver. Class B certification is more restrictive than the commercial Class A certification.
   See also Class A certification.
