FCC Rule Part 15b – Declaration of Conformity (DoC) & Verification
The Federal Communications Commission (FCC) requires most digital device sold in the United States to meet the requirements of (CFR 47) rule part 15, subpart b. The FCC rule part 15b is not a new requirement; however it is often one of the most over-looked requirements exposing the “responsible party” to FCC enforcement and potential fines.
The FCC rule part 15b focuses on “unintentional” radiation or noise generated by a digital device. This noise could potentially impact the operation of other devices in a close proximity and therefore requires testing of the unintentional radiators.
The FCC 15B is a self-declaration process, not a certification. There is no certificate or document received from the FCC once the testing in completed. This self-declaration encompasses both the verification and DoC or Declaration of Conformity testing. While this is a self-approval process, it does not mean that just anyone can perform the testing. The rule part currently specifies that for verification testing, the testing must be performed by a lab that has its test site registered with the FCC. The requirement for DoC, (Declaration of Conformity) testing is that the testing must be performed at an accredited test lab. An accredited lab can issue a certificate for DoC or a statement of compliance.
A wide variety of devices are currently subject to the FCC Part 15b rule part, including personal computers and peripherals, consumer, industrial, scientific and medical equipment, music equipment, radio receivers, and TV interface devices to name a few.
Common misconceptions about Verification and Declaration of Conformity (DoC) testing:
- My device doesn’t have a transmitter so I don’t need any testing.
- I’m using an unlicensed radio so I don’t need any testing.
- I’m using a pre-certified module, so I don’t need any testing.
- “Self-Declaration” means testing is optional.
