UL's EMC testing services

U.S. EMC requirements - FCC Compliance Testing

UL is accredited to conduct FCC compliance testing to the EMC requirements of the U.S. Federal Communications Commission (FCC) through the National Voluntary Laboratory Accreditation Program (NVLAP - NVLAP LAB CODE 100255-0). UL's EMC facilities are included in the FCC's list of testing sites for radio frequency emissions testing.

The FCC Declaration of Conformance (DoC)

The deregulation that took effect in 1996 lifted equipment authorization requirements from the FCC Grant of Certification to a new self-authorization process for personal computers and peripheral devices. This new process is based on the manufacturer or supplier's Declaration of Conformity (DoC) limiting radio frequency (RF) emissions.

To self-declare for the DoC, the FCC requires that EMC testing be conducted by laboratories accredited by the National Institute of Standards and Technology (NIST) through the National Laboratory Accreditation or other programs approved by the FCC. UL is accredited through NVLAP (NVLAP LAB CODE 100255-0) and experienced in conducting these tests for personal computer and peripheral device manufacturers.

The old FCC identification label is replaced with a new simplified label that includes a compliance logo. The new FCC ID labels differentiate main computer boards and power supplies from personal computers assembled from separate components.
