Joëlle Driessen-Verkuijlen, responsible for maintenance contracts, explains how we prevent doors from leaking with the risk that your EMC measurements are compromised due to insufficient shielding attenuation: “Most of the chambers we install come with annual maintenance contracts. Our specialists, such as Edwin, travel worldwide for maintenance, such as cleaning the contact surfaces of the doors and the door frames. We call those door-knives and finger stocks. You can see Edwin cleaning these copper finger stocks in the photo. These must be cleaned with the proper solvent because some cleaning products leave residues, worsening the problems. While inspecting and cleaning, our mechanics can also replace worn-out finger stocks, preventively replace the batteries of automatic doors every two years, and, upon request, do maintenance on small turntables and antenna masts.”
If you have a test chamber or RF-shielded room with a creaking or stiff door and want to know what our experts think of it, send a photo of the finger stocks and/or door blades to Joëlle Driessen-Verkuijlen, and she and her team of experts will tell you what to do.
We were surprised by the results of our poll to determine if the market prefers end caps on their absorbers. The results were quite clear! Two responses received 88% of the votes, leaving little room for the other two options.
More and more test labs and automotive OEMS are embracing reverberation testing. But who possesses the expertise to operate a reverberation test setup? Professor Frank Leferink from the University of Twente is launching a unique 5-day course for professionals transitioning to reverberation testing this September. As a friend of the university, we offer you a generous discount.

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.
