Federal Communication Commision (FCC) EMC compliance for North America
FCC EMC Compliance Testing for North America and associated countries
A brief description of FCC EMC compliance testing, approval & certification
Expansion: Federal communications commission
Effective region: Independent agency of the United States covering all 50 states, the District of Columbia and U.S territories.
Regulator: The Federal communications commission is an independent agency of the United States government created by the congressional statute.
Legal Requirements: Mandatory
AC Mains supply: 120VAC 60Hz
Important FCC compliance facts:
FCC compliance testing requirements involve Radiated emissions testing, this testing can only be performed on a compliant test site (ANSI C63.4: 2014). Our test site is compliant with all the requirements.
Countries requiring the FCC marking
FCC marking is mandatory for certain product groups within all 50 states, District of Columbia and the territories (American Samoa, Guam, Northern Marianas Islands, Puerto Rico, Virgin Islands).
FCC Legal implications
Each product must be tested to the relevant applicable section of the Federal communications commissions rules at a registered and accredited test site. The federal communications commission requires products to meet the relevant emissions requirements section. A local representative is required for declaration of conformance. Intentional radiators (Transmitters) must have the test report and associated technical documentation submitted to the Federal communications commission or a designated TCB (Telecommunications Certification Body/Technical conformity body).
FCC Routes to compliance
FCC Verification (Replaced by SDoC, see below)
Note: This process ended on November 2, 2017, but was transitioned until November 2, 2018.
Verification requires the party responsible for compliance to ensure that the equipment complies with appropriate technical standards. Submission of a sample or representative data to the FCC demonstrating compliance is not required unless it is requested by the FCC. Devices subject to verification include Industrial, Scientific and medical (ISM) equipment, business class A computer equipment, TV and FM receiver.
Supplier’s Declaration of Conformity (SDoc)
Supplier’s Declaration of Conformity (DoC) requires the party responsible for compliance to ensure that the equipment complies with the appropriate technical standards. The responsible party must be located in the United States, is not required to file an equipment authorization application with the Commission or a Telecommunications Certification Body (TCB). Equipment authorized under the SDoC procedure is not listed in a Commission database. However, the responsible party or any other party marketing the equipment must provide a test report and other information demonstrating compliance with the rules upon request by the Commission. The responsible party has the option to use the certification procedure in place of the SDoC procedure.
Note: Products that were subject to either the Declaration of Conformity (DoC) or verification equipment authorization procedures in the past are not required to be changed and updated under the new SDoC requirements, as long as the devices remain unmodified.
Certification is the most rigorous approval process, the approval process is used for RF Devices as these have the potential to cause interference to radio services. Certification is an equipment authorization issued by a designated Telecommunications Certification Body (TCB). The certification is based upon evidence such as test reports issued by FCC recognized accredited testing laboratories. Equipment authorized under the Certification procedure is listed in a Commission database (accessible by the public). In addition, equipment subject to approval using the Supplier’s Declaration of Conformity (SDoC) such as equipment that only contains digital circuitry (does not contain a radio transmitter) procedure can optionally use the Certification procedure.
Why use EMC Bayswater for your FCC testing, compliance and certification needs?
We are NATA accredited for FCC Part 15B which includes NATA accreditation to ANSI C63.4. Utilising a fully compliant ANSI C63.4-2014 iOATS chamber. A requirement for radiated emissions measurements (30MHz to 40GHz radiated emissions). Please visit our EMC testing services page for details of other EMC compliance testing services we offer.

FCC logo and Labelling
Depending upon the product classification may mean that you only need to provide a statement in the documentation otherwise a separate marking may need to be permanently affixed to your product.
For further information on the FCC product labelling requirements please refer to the Office of Engineering and Technology (OET) FCC Quick labelling Guide.
The FCC Quick labelling Guide is excellent to quickly check your products labelling requirements. Please click the following link for information on the FCC labelling requirements and guidelines.
For EMC testing of Radio Frequency LED Lighting Products, please refer to the OET notice “FCC – Radio Frequency LED Lighting EMC Testing Notice“
In some situations, both certification and Supplier’s Declaration of Conformity (DoC) could be applied. An example would be a mobile phone, certification is used as evidence of compliance for an installed modular radio intentional transmitter and Supplier’s Declaration of Conformity (DoC) used for the unintentional digital circuity. It must be noted that the frequency range under investigation for FCC Part 15 Subpart B EMC testing will be affected. Affected by either the highest frequency used, generated or tuned by A) Host or B) Radio module. If the highest of the two is above 1GHz and is the host then up to the 5 harmonic is to be considered. Yet, if the highest is the radio module then the tenth harmonic of the radio module must be considered.
Can I use results from CE or RCM testing
It may be possible to use the same results depending upon the methodologies used (as many of the intentional radiators/transmitter testing methodologies vary between FCC and CE). If the product is mains powered it must be powered by 120VAC at 60Hz. It may be possible to use the CE radiated emissions results if your product has a DC input port and a separate AC/DC plug pack that is already FCC and CE compliant (but conducted emissions is still required).
