FCC PART 15


If you are wondering what type of radio frequency testing is needed for your product, take a look at the information below to help clarify what type of testing you need- or, if you even need testing.

All electronic devices (unintentional radiators) that contain clocks/ oscillators, which operate at a frequency of 9 kHz, must be tested under FCC part 25 Subpart B, radio frequency rules and regulations. The FCC has broken down Part 15 into two categories, Class A and Class B.

Class A Device
A device that is marketed for use in an industrial application and is not intended for use in the home or residential area.

Class B Device
A device that is marketed for use in the home or a residential area by the customer.

Class B Verification Class B verification is for devices that are marketed for in home use but not permanently connected to a personal computer. It is recommended that testing be performed at an Open Area Test Site. Upon approval, the laboratory prepares a report and you keep a copy on file.

Class B Certification

Class B Certification is for personal computing devices or peripherals that are marked for residential use. This process is more time consuming because after the laboratory prepares a report, it is sent to the FCC for review before your chosen FCC ID is granted and added to their list of approved products. Typical application delay at the FCC is 30 days. Under the new procedures for DoC/Self Declaration there is no longer a need to submit/certify computing devices and peripherals with the FCC.

LTG utilizes competent and experienced FCC approved laboratories to perform DoC procedure testing. Testing time is available, so call now.
