FCC Part 15 - Certification

Certification is the most rigorous approval process for RF Devices with the greatest potential to cause harmful interference to radio services. The authorization is issued by an FCC-recognized Telecommunication Certification Body (TCB) based on the evaluation of the documentation submitted by the responsible party. Testing must be performed by an FCC-recognized accredited testing laboratory. Information including the technical parameters and descriptive information for all certified equipment is posted on an FCC maintained public database.1


Clients may call or email VPI Laboratories to request information regarding the testing, procedures, and fees for FCC certification of their equipment.


The information and materials listed under 'Materials Required for FCC Declaration of Conformity' lower on this page are required by VPI Laboratories to be able to complete FCC Part 15 Certification. VPI will review the materials when received. If additional information is required, VPI will contact the client.

Work Time

VPI Laboratories will begin work when required information, equipment, purchase order, and required deposit are received. The project can normally be completed within two to four weeks.


If the equipment fails to meet the test requirements, VPI Laboratories will notify the client to outline the failures. Depending on the service requested by the client, VPI will work to determine and/or correct the possible sources of the failures. If the failures cannot be corrected with the sample VPI has, an outline of where the problems originate and design changes that may correct the failures will be given to the client. If the failures continue, the client may take the following actions:

  1. Schedule time to have an engineer familiar with the design and operation of the equipment come to VPI and assist in finding the proper modifications to the unit.
  2. Send a list of possible modifications for VPI personnel to make on the unit.
  3. Send a unit with modifications already installed.

If the problems cannot be resolved in a reasonable length of time, the client will be invoiced for the work completed to date on a prorated basis. VPI will continue to assist the client in any way. A new quote will be issued for the remaining work once the corrections have been made.


After the satisfactory completion of the tests, VPI Laboratories will organize the test data and filing materials into a complete FCC report. A copy of the report will be delivered electronically to the client for their records. The FCC report will be submitted to the Telecommunications Certification Body (TCB) for approval through the FCC.

TCB Grant

The FCC has created the Telecommunication Certification Body (TCB) program to allow independent laboratories to provide equipment certification through the FCC. VPI Laboratories will use a TCB which means that we can now grant the equipment certification through the TCB program. Once all the necessary documents are received, the FCC TCB Grant process normally takes about one to three weeks. Or you have the option of using a TCB of your choice.


The equipment can now be sold in the U.S. as a Part 15 Certified device.


  1. Equipment: One (1) set of the equipment to be certified. The interconnecting cables, power supplies, and software must be included. If the equipment is a computer peripheral, it must be tested with a host computer. The host computer must have the necessary software installed to interface with the equipment under test. Any additional peripherals needed to form a complete "system" are required.
  2. Client's contact name, address, and phone number.
  3. Applicant company name and address.
  4. Manufacturer company name and address.
  5. FCC Identification number.*
  6. Model number(s) and/or trade name(s) of the equipment to be certified. Specify differences between the multiple model numbers.
  7. Schematic diagram(s) of equipment being certified.
  8. Block diagram showing the signal paths and clock frequencies of the equipment being certified.
  9. User's operating/installation manual which contains the required FCC statements.*
  10. Additional instructions if needed for VPI to operate and install the equipment properly for testing.
  11. The actual FCC label is to be affixed to the device. This may be submitted as a photograph, engineering drawing, or actual sample.*
  12. A diagram showing the FCC label placement on the equipment.

* Additional information is available from VPI explaining these requirements.
