Wireless Device EMC Testing and Certification

Expansion of frequencies in wireless device 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 EMC requirements before launch. Our pre-compliance testing can enable you to detect and resolve potential design flaws early in the process to reduce design costs and accelerate market launch.

EMC compliance testing requirements

No one global EMC compliance testing standard exists. Requirements vary from country to country, and regulations are continually evolving. At UL Solutions, we stay on top of these changing EMC requirements so you don’t have to. Our experts keep track of the changes and 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.    

CISPR 32, 35 and the evolution of multimedia standards

The International Special  Committee on Radio Interference (CISPR) is one of the central publishers of EMC standards. Testing standards have continued to expand to accommodate technological advances.    

• CISPR expansion
  For example, in the 2000s, the noisy frequency band of PCs called for a standard that could handle emissions from information technology (IT) devices. This led to CISPR 22 (emissions standard) and 24 (immunity standard). These replaced CISPR 13 and 20, which themselves only covered audio and broadcast receivers (AV equipment) such as radios and televisions.
• CISPR 32, 35 solutions
  Soon, the advent of microcomputers and multimedia tech presented the problem of covering both AV and IT, leading to CISPR 32 (published 2012) and 35 (published 2018). The challenge to create an emissions standard that covers both AV and IT equipment was solved by integrating traditional applications from the last two CISPR iterations. CISPR 32 covers traditional CISPR 13 and 22 applications, while CISPR 35 covers CISPR 20 and 24 applications.

The importance of MRAs globally

The Mutual Recognition Agreement (MRA) is a bilateral agreement that allows the certification of equipment from one country to be carried out in another. The signing of an MRA facilitates the import and export of telecommunications equipment, electrical appliances, etc., with the aim of reducing the burden on companies and promoting bilateral trade.

Our EMC testing solutions can help you meet global requirements and regulations

Automation

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 global laboratories follow standardized testing plans. We can provide redundancy and the ability to move staff and projects around to meet surge demands for accelerated product launches.
• Remote Witnessing of Test allows you to work in real time with the engineers testing your products, that helps you save time to travel to a test laboratory.

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.
