Behind this chamber lies an unexpected and remarkable story of courage and entrepreneurship that we really need to share with you. On June 1, 2024, two young and ambitious technicians in Germany, Josip Brkic and Francesco Iemma, moved into the building housing their company, Black Forest Testlab, with the fully compliant CISPR-16 Anechoic Chamber shown in the photo, which we built for them.
This is a man who loves the impossible. After seven years, we welcome Martijn Fokker back to the Comtest family. “I have been working at Comtest for 16 years and thought it was time for something different, but there’s something about these chamber projects that kept me coming back,” says Martijn.
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.

Neglecting proper maintenance of test chamber doors can result in considerable performance loss. Our Service Engineer, Edwin Van Der Ploeg, explains the associated risks and offers guidance on mitigating them.
Edwin: “When I carry out an H-Field measurement, I measure the doors four times across seven points at varying frequencies. During these measurements, I verify whether these seven points comply with the standards. When these points do not exhibit radiation within the standards, it is often due to dirt. Ideally, you want 100 per cent steel on steel without any interference from other materials, such as dirt, which creates unwanted isolation. When testing at higher frequencies, dirt significantly reduces contact between the leaf and the door frame.”
So what do you advise, Edwin?
Edwin: “The section of the doorpost in the photograph I’m referring to is known as finger stocks and is a typical area where dirt, dust, corrosion, liquids, and grease create issues. The challenge is that some forms of contamination are not visible to the naked eye. Prevention is crucial; the best approach is to inspect the doors annually. You wouldn’t want to disassemble the door and replace all its components.”
