EMC & EMI Testing Services
VPI Technology Specializes in Unintentional Emissions, Intentional Transmitters, and Immunity/Susceptibility Testing
What Is EMC Testing?
Electromagnetic compatibility (EMC) measurements are required by most governments throughout the world. EMC is an important regulatory compliance issue for electronic equipment manufacturers. Governments require that electronic products do not interfere with each other’s operations. When a product is designed well, basic EMC principles are applied such as shielding, grounding, and filtering for improved electromagnetic immunity. With the increased use of wireless communications, the potential for interference is also growing. Your device is compatible with EMC regulatory requirements when it does not intentionally or unintentionally interfere with the operation of other electronic devices. That compliance is demonstrated by test reports generated by an accredited laboratory.
EMC Testing Labs
VPI Labs has fully equipped facilities located in Draper, UT, and Wanship, UT; including 10 and 3-meter open area test sites and a 3-meter anechoic chamber, needed to perform the EMC measurements and generate compliance reports you need to sell your electronic products in compliance with governmental regulations in most countries. VPI is accredited by NVLAP (Test Lab Code: 100272-0) to perform emissions and immunity measurements to a wide range of international and domestic regulatory standards. Our Scope of Accreditation is here: Scope of Accreditation.
EMC Precompliance Testing
At VPI, we offer precompliance testing services to help manufacturers avoid costly redesigns and modifications. Our anechoic chamber and open-area test site in Wanship, Utah, provide accurate and efficient testing services, using the latest software and blocking out ambient noise. With our precompliance testing, you can identify any potential issues before full compliance testing, saving time and money.
We provide precompliance testing for Federal Communication Commission (FCC) Part 15 rules, telecommunication certification body (TCB) requirements, CE marking rules, EN 55032 emission standards, 5GHz Wi-Fi, and more.
EMC Immunity Testing
Our Draper, UT facility is one of the nation’s finest Electromagnetic Compatibility (EMC) test environments and features a compact 3-meter anechoic chamber where automated pre-compliance emissions and radiated susceptibility tests are performed. In addition to our anechoic chamber, we also have a dedicated partially screened room for ESD testing.

EMC Compliance and Certifications Services
FCC Certification – Part 15 & Part 18
VPI offers testing to cover FCC compliance requirements for your product under its Supplier Declaration of Conformity (SDoC), and Certification designations. *FCC Part 15 covers testing that determines if electronics fall under certain limits of electromagnetic interference and FCC Part 18 covers testing for industrial, scientific, and medical equipment for conducted and radiated emissions.
Industry Canada (IC) Testing
IC EMC compliance falls under Canada’s Institution for Innovation, Science, and Economic Development (ISED). VPI offers testing to cover IC compliance requirements for your product under its Supplier Declaration of Conformity (SDoC), and Certification designations.
More Information on Industry Canada (IC)
Innovation, Science, and Economic Development Canada (ISED), also known as Industry Canada (IC), serves as the certification body for intentional and unintentional radiators, overseeing technical specifications, administrative requirements, and marketing conditions related to these devices. The compliance process with ISED depends on the type of equipment and can be achieved through either a supplier’s declaration of conformity or certification. Certification involves the responsible party ensuring testing is completed and taking necessary steps to ensure compliance with relevant technical standards. The test report and supporting documents are submitted to ISED through the Telecommunication Certification Body (TCB) process, and compliant equipment is labeled with an IC ID number and verification requirements. ICES‑003 establishes different limits for radio noise emission in information technology equipment (ITE), with Class A limits for non-residential operation and Class B limits for residential operation. ITE strictly intended for non-residential use may comply with Class A limits, while all other ITE must comply with Class B limits. Compliance with both conducted and radiated emissions limits for power lines is required, with no intermixing of classifications permitted. RSS-210, RSS-247, and RSS-Gen standards apply to intentional radiators, including various devices such as cable-locating equipment, cordless telephones, remote control and alarm transmitters, field-disturbance sensors, and spread-spectrum systems. Intentional radiators governed by ISED must either have a permanently attached antenna or feature a unique connector to prevent unauthorized antenna use. The operation of radio transmitters is subject to rules governing fundamental field strength, power, power density, frequency accuracy, and permitted harmonic and spurious emissions.
See the ISED website for more information.
