Tips & Trends for 2026: #1: Automotive and Reverberation?

Engineers analyze automotive reverberation technology in a modern office setting.

Will 2026 finally see the adoption of reverberation testing in the automotive industry? In a series of five posts, our specialists share trends and developments for 2026. This week, Dimitrios Barakos, R&D Engineer at Comtest, explains the delays in 2025.

Dimitrios: “Although the ISO standard for full-vehicle testing was completed some time ago, the necessary ISO-11542-11 update for automotive components has been pushed back. There is a bright side: in 2027, Hyundai Motor Group will likely make the updated ISO standards mandatory for testing their vehicles and motor components. However, that was expected in 2025 and has been delayed, as you know. For 2026, these delays will leave the automotive industry with only half the incentive to embrace reverberation testing.”

When do you see acceptance for reverberation testing in the automotive industry?

Dimitrios Barakos: “The point is that the new norms for full-vehicle testing are not mandatory, and switching from anechoic to reverberation testing is not very popular. Some companies are open to it, and big labs and test houses see the potential of reverberation testing, but for many, it remains an unfamiliar method. At the Comtest R&D department, we continue developing improvements to our reverberation chambers. We have been optimising our current range of stirrers, and we are also working on a new type of stirrer. We keep improving the product to stay ahead of the game.”

Comtest delivers EMC testing expansion for TREO

Doubling a lab’s measuring capacity in a very short timeframe: another example of the demand for EMC testing chambers in Europe. In this case, we helped our friends at Treo – Labor für Umweltsimulation GmbH, an independent service provider for product and component testing in the Hamburg area in Germany.

Our services include maintenance and validated testing. We recommend that both are executed by authorized personnel only. Our expert teams can perform preventive maintenance on RF-shielded doors, mode-stirrer systems, and positioning equipment such as turntables. We also offer validation services to see if your EMC test chamber or RF-shielded room still functions within its intended limits and avoiding unexpected down-time or product recalls at the same time.

A shielded room can perform conducted emission and immunity EMC measurements, eliminating harmful external influences, leading to more accurate and consistent test results. Being a Faraday cage, a shielded room will not only improve test results but will also form an excellent aid in protecting information and essential hardware. Comtest can assist governments, the military, financial institutions, and large corporations in protecting what matters most in critical situations. We offer the highest quality, sensitivity, and security before, during and after working with you.
