EMC compliance testing 

Unintended interactions and signal interference between electronic products, as well as equipment emissions, can have adverse impacts on electronic devices and radio systems. For this reason, in many countries new products must comply with electromagnetic compatibility (EMC) requirements before launch. Our pre-compliance testing may enable you to detect and resolve potential design flaws early in the process to reduce design costs and accelerate market launch.


No global EMC compliance testing standard exists. Requirements vary from country to country, and regulations are continually evolving. At UL, we stay on top these changing EMC requirements so you don’t have to. We design the newest testing plans to meet new requirements and keep track of the changes in the required paperwork for your product to gain market access to more than 150 countries. We have been conducting compliance and pre-compliance testing for more than 20 years, and our solid reputation means you can trust your testing is performed correctly the first time, reducing your worry about product returns and recalls. 

EMC testing solutions to help meet global requirements and regulations


Automated EMC testing increases efficiency helping to get your products evaluated and to market sooner. It also increases consistency of test results and data across our global suite of test laboratories, making your global market launch more seamless. 

Accredited EMC testing laboratories

Our full-service EMC laboratories, equipped with state-of-the-art semi-anechoic chambers, hold important accreditations and are recognized by various regulatory bodies.

  • Our engineers have an average of 30 years of experience in the field of EMC measurement and regulatory requirements.
  • UL’s global laboratories follow standardized testing plans and have synchronized reporting systems so you can expect consistent results no matter where you do business with us. Our network of global laboratories provides redundancy and the ability to move staff and projects around to meet surge demands for accelerated product launches.
  • Remote Witnessing of Test lets you work in real-time with the engineers testing your products without the need to spend time and money traveling to a test laboratory. 
  • We can provide nearly all your testing, verification and compliance needs in one location, increasing efficiency and decreasing costs and time to market launch.

Emission and immunity testing

Our global network of state-of-the-art emission, immunity testing and millimeter wave (mmWave) testing laboratories and security systems keep your proprietary designs protected.

We can tailor EMC test methodology and documentation to your own specifications to help ensure the most efficient use of your time and budget.

Services by industry

With our EMC testing and certification solutions, we serve a wide range of industries worldwide, including:

  • Consumer electronics
  • IT equipment
  • Audio/visual equipment
  • Mobile and telecommunication 
  • Medical technologies
  • Small and major appliances
  • Industrial electronics
  • Automotive

Auto industry benefits

Vehicle electronic subassemblies and components pose unique testing challenges to recreate the in-vehicle device operation and monitor performance in a laboratory setting. Our expert engineers assist automotive suppliers with original equipment manufacturer (OEM) recognized EMC validation testing of varied component types, such as switches, motors, electronic control units (ECUs), lighting assemblies, electric vehicle (EV) battery control modules and even complex infotainment modules to meet OEM testing requirements.

To help you gain access to the European market, we are designated to test automotive electronic/electric subassemblies (ESAs) for compliance with the Vehicle Type Directive and the E Mark certification of components.
We can advise you on whether a product is an immunity-related device (integral to the working of the vehicle), which may need additional testing in order to gain market approval.

Medical industry benefits

For medical products, IEC 60601-1-2 fourth edition has significant changes that impact both testing and risk management related to basic safety and essential performance. On Dec. 31, 2018, this standard became mandatory for new product submittals to the U.S. Food and Drug Administration and medical products entering the European Union. This standard requires that risks resulting from reasonably foreseeable electromagnetic disturbance be taken into account in the risk management process and references ISO 14971, Medical Devices – Application of Risk Management to Medical Devices.
