If your product contains digital electronics, microprocessors, or switching power supplies, it may unintentionally emit radio frequency (RF) energy—and likely qualifies as an Unintentional Radiator under FCC Part 15.
Before you market it in the U.S., you may need to complete FCC compliance steps such as Supplier’s Declaration of Conformity (SDoC) or full equipment certification.
At American Certification Body (ACB), we help you understand what’s required and guide you through the right certification path for your unintentional RF-emitting device.
What Are Unintentional Radiators?
Unintentional Radiators are devices that generate RF energy during normal operation, even though they’re not designed to transmit signals. Common examples include:
- Computers and laptops
- Microcontroller-based products
- Digital displays and monitors
- Switching power supplies
- USB hubs and peripherals
- Industrial control systems
These emissions can interfere with licensed radio services, which is why FCC Part 15 Subpart B sets strict limits and compliance requirements.
Do I Need FCC Certification for an Unintentional Radiator?
Yes, in most cases. If your product includes digital circuitry operating above 9 kHz, it’s likely considered an Unintentional Radiator and must meet FCC Part 15 requirements.
There are two main compliance options:
- Supplier’s Declaration of Conformity (SDoC)
- Suitable for many consumer and commercial electronics.
- Requires testing by an accredited lab, but no formal FCC filing.
- Certification through a TCB (like ACB)
- Required for certain devices (e.g., products with TV tuner receivers).
- Involves lab testing and a formal grant process.
We’ll help determine which route your device falls under—and support you through it.
ACB’s Role in Certifying Unintentional Radiators
ACB is a recognized Telecommunications Certification Body (TCB). We specialize in reviewing test data, confirming FCC compliance, and issuing Grants of Equipment Authorization where required.
We don’t operate a test lab—we’re a truly independent certification body, giving you the flexibility to use your preferred test provider.
Why Work with ACB?
✅ Expert Guidance – We help you understand the right path (SDoC vs. Certification)
✅ Fast Turnaround – Reviews are typically completed in just a few business days
✅ Flexible Lab Choice – Use your own lab or one from our trusted network
✅ Clear Support – We guide you through test planning, labeling, and documentation
FCC Compliance Process for Unintentional Radiators
- RF Emissions Testing
Conducted at an FCC-recognized lab to evaluate unintentional emissions (radiated & conducted). - Compliance Path Determination
We help you determine whether SDoC or Certification applies to your device. - Documentation Review
ACB reviews test reports and supporting documents (for certification-required devices). - FCC Authorization (if required)
If certification is needed, ACB issues your FCC Grant of Equipment Authorization and assigns an FCC ID. - Labeling & User Manual
Devices must include specific FCC statements and be labeled according to Part 15 requirements.
Common Questions About Unintentional Radiator Compliance
Q: What’s the difference between SDoC and Certification?
A: SDoC involves less paperwork and no FCC filing—it’s common for digital devices. Certification is a formal FCC process used for specific device types.
Q: Does my product need to be tested?
A: Yes. All Unintentional Radiators must undergo RF emissions testing by an accredited lab.
Q: Can I use my own lab?
A: Absolutely. As long as the lab meets FCC requirements, you’re free to use your own. We can also refer you to one if needed.
Q: How do I know which path to take?
A: We’ll help you figure that out. It depends on your device’s classification under Part 15.
