FCC Part 15 Testing
FCC Part 15 Testing for Electronic and Wireless Products
Stancer Testing-Lab offers FCC Part 15 compliance testing as part of EMC testing for intentional and unintentional radiators targeting the US market. Our lab tests both unintentional radiators under FCC Part 15 Subpart B and intentional radiators under FCC Part 15 Subpart C. Testing includes conducted and radiated emissions per FCC Part 15 Subpart B, and RF tests such as output power, occupied bandwidth, band-edge, and spurious emissions per FCC Part 15 Subpart C.
Tests We Perform
Conducted Emissions
Measurement of RF disturbances conducted onto AC mains and other applicable interfaces in accordance with FCC Part 15 Subpart B and the test methods outlined in ANSI C63.4.
Radiated Emissions
Measurement of electromagnetic emissions from electronic and digital devices in accordance with FCC Part 15 Subpart B.
RF Output Power Test
Measurement of transmitter output power using applicable conducted or radiated methods based on the radio technology and FCC Part 15 Subpart C.
Occupied Bandwidth
Evaluation of transmitter bandwidth and spectral characteristics to verify operation as per FCC Part 15 Subpart C.
Band-Edge Measurements
Verification of emissions near the boundaries of authorized frequency bands to demonstrate compliance with applicable band-edge limits outlined in FCC Part 15 Subpart C and ANSI Standard C63.10.
Spurious & Unwanted Emissions
Measurement of harmonics, out-of-band emissions, and other unwanted transmitter emissions as outlined in FCC Part B, Subpart C.

FCC Part 15 Testing and Certification Process
Stancer Testing-Lab supports manufacturers through the technical evaluation and documentation steps required for FCC Part 15 compliance and equipment authorization. The exact pathway depends on the device type, radio technology, and applicable FCC rule section.
01
Product Review
We review the product architecture, radio functions, operating frequencies, interfaces, and intended use to identify the applicable FCC Part 15 requirements.
02
Test Plan
A test plan is prepared based on the applicable rule sections, required measurements, product configuration, accessories, operating modes, and supporting documentation.
03
Laboratory Testing
The product is evaluated for the applicable conducted, radiated, and RF parameters using recognized test methods and laboratory instrumentation.
04
Test Report
Test results are compiled into the required technical report with product configuration, measurement data, test setup details, and compliance results.
05
Equipment Authorization Support
Where certification is required, Stancer can support preparation of the technical documentation needed for submission through the applicable FCC certification pathway.
06
U.S. Market Access
Once the applicable FCC authorization requirements are satisfied, the product can proceed toward compliant distribution and sale in the United States.
FCC Part 15 Testing FAQ
What is FCC Part 15 testing?
FCC Part 15 testing evaluates electronic and wireless products against technical requirements that limit radio-frequency emissions and, for intentional radiators, regulate transmitter characteristics such as output power, occupied bandwidth, band-edge emissions, and spurious emissions.
What is FCC Part 15 Subpart B?
FCC Part 15 Subpart B applies to unintentional radiators, including many digital and electronic devices that generate RF energy during normal operation. Typical testing includes conducted and radiated emissions.
What is the difference between an unintentional radiator and an intentional radiator?
An unintentional radiator generates RF energy as a by-product of its operation, while an intentional radiator deliberately transmits RF energy for communication or sensing. The applicable FCC Part 15 requirements and test methods differ between the two categories.
Which products may require FCC Part 15 testing?
Products such as digital devices, industrial electronics, computing equipment, IoT products, wireless devices, Bluetooth products, Wi-Fi devices, Zigbee devices, and other equipment containing digital circuitry or radio transmitters may be subject to FCC Part 15 requirements.
Does FCC Part 15 testing always require FCC certification?
No. The applicable equipment authorization pathway depends on the product and FCC rule section. Some unintentional radiators may be subject to Supplier’s Declaration of Conformity requirements, while many intentional radiators require FCC certification.
What measurements are commonly performed for FCC Part 15 compliance?
Depending on the device, testing may include conducted emissions, radiated emissions, RF output power, occupied bandwidth, band-edge measurements, harmonics, spurious emissions, and other measurements required by the applicable FCC rule section.
Can FCC Part 15 testing be performed in Canada?
Yes. FCC compliance testing can be performed by qualified laboratories outside the United States when the applicable FCC requirements, measurement procedures, and equipment authorization requirements are satisfied.
Can Stancer support both FCC and ISED testing?
Yes. For many electronic and wireless products, FCC and ISED requirements can be evaluated within a coordinated test program, helping manufacturers prepare for both U.S. and Canadian market access.
