What is FCC Certification Part 15?(图1)

FCC Part 15, that is, Part 15 of the US FCC certification 47CFR, FCC Part 15 is the electromagnetic interference standard (conducted interference, radiated interference) for radio frequency devices (intentional and unintentional radiators). Radio frequency devices refer to any device that can emit radio frequency energy by radiation, conduction or other means during its operation. Most electronic devices are radio frequency devices. This regulation stipulates that electronic products in this category need to be FCC certified before they can enter the US market.

What is FCC Certification Part 15?(图2)

FCC Part 15 consists of several subparts:

◉ Subpart A - General

◉ Subpart B - Unintentional Radiators

◉ Subpart C - Intentional Radiators

◉ Subpart D - Unlicensed Personal Communications Service Devices

◉ Subpart E - Unlicensed National Information Infrastructure Devices

◉ Subpart F - Ultra-Wideband Operation

◉ Subpart G - Access Broadband Over Power Line (Access BPL)

◉ Subpart H - Television Band Devices The most common ones are Subpart B and Subpart C. Subpart B and Subpart C will be introduced in detail below.

Device Type
Class A digital deviceThe sale of digital equipment for use in a commercial, industrial or business environment does not include the sale of equipment for public use or intended for use in the home.
Class B digital equipmentDigital devices sold for use in residential settings, although used in commercial, business, and industrial settings. Examples of such devices include, but are not limited to, personal computers and similar electronic devices sold for use by the public.

Appendix 1: Classification of digital devices


Subpart B's EMC standards mainly include the following:

Except Class A digital equipment
EMC StandardsTest contentTest MethodRequire
ANSI C63.4-2014RE radiated interferenceThe radiation of unintentional radiators at a distance of 3 meters shall not exceed the limit30-88 MHz,40db(quasi-peak);
88-216Hz,43.5db(quasi-peak);
216-960MHz,46db(quasi-peak);
Above 960MHz, 54db (quasi-peak).
CE conducted interferenceEquipment connected to the public (AC) power lines shall not conduct radio frequency voltages back into the AC power lines at any frequency or frequencies in the frequency band 150 kHz to 30 MHz, when measured using a 50 μH/50 ohms Line Impedance Stabilization Network (LISN)0.15-0.5MHz, 66 -56db(quasi-peak),56-46db(average);
0.5-5MHz,56db(quasi-peak),46db(average);
5-30MHz,60db(quasi-peak),50db(average)。


Class A digital device
EMC StandardsTest contentTest MethodRequire
ANSI C63.4-2014RE radiated interferenceThe radiation of unintentional radiators at a distance of 10 meters shall not exceed the limit30-88 MHz,39db(quasi-peak);
88-216Hz,43.5db(quasi-peak);
216-960MHz,46.4db(quasi-peak);
Above 960MHz, 49.5dB (quasi-peak).
CE conducted interferenceEquipment connected to the public (AC) power lines shall not conduct radio frequency voltages back into the AC power lines at any frequency or frequencies in the frequency band 150 kHz to 30 MHz, when measured using a 50 μH/50 ohms Line Impedance Stabilization Network (LISN)0.15-0.5MHz,79db(quasi-peak),66db(average);
0.5-30MHz,73db(quasi-peak),60db(average)。




Applicable products of Subpart C, i.e. products with wireless remote control (FCC ID required), include:

Such as door card reader, bus card reader, wireless charger, remote control toys, wireless mouse, remote control switch, wireless doorbell, anti-theft device, Bluetooth speaker, WIFI drone, smart home products.

Note: Infrared remote control does not belong to wireless remote control, but belongs to subpart B, so you only need to do FCC SDOC.


Subpart C's EMC standards mainly include the following:
