Last week, our consultants, Hanneke van Veen and Dimitrios Barakos, visited seven companies in Japan with our friends from Microwave Factory to help companies implement the closed-loop power control (fast stirring) reverb method as per the ISO11451-5 test standards.
This table can support objects weighing up to 750 kilograms and complies with MIL-Standard for the defence industry. Let us share more details about our production line’s strongest testing table.

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.

At the time, Dutch table tennis legend Bettine Vriesekoop, born near the Comtest office, became the European Champion in 1982, igniting the sport’s popularity.
