Certification and Registration
Introduction to FCC Part 15
Category:
U.S. FCC
FCC Part 15, also known as Part 15 of 47 CFR under U.S. FCC regulations, specifies electromagnetic interference requirements for radio frequency devices (intentional and unintentional radiators), including conducted and radiated emissions. Radio frequency devices refer to any equipment capable of emitting radio-frequency energy through radiation, conduction, or other means during operation. Most electronic products fall under this category. According to this regulation, such electronic products must obtain FCC certification before entering the U.S. market.
FCC Part 15 It consists of several sub-sections:
◉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
