Pre-compliant or full-compliant?

In this post, we explain why purchasing a test chamber that is not fully compliant can be very interesting. “It can save money and space,” says our technical advisor, Marc Le Roy. He explains how we helped the KU Leuven Brugge with an efficient and affordable solution.

Marc: “There is a difference between relevant and acceptable measurements. Take CISPR16-1-4, for example; to be fully compliant, you must have a chamber at least 5,5 meters high to perform a 4-meter height scan. Some of our clients do not have that height available; the additional information from the height scan is limited. In those cases, a pre-compliant chamber is almost just as effective because it still helps them test during the development stage of a product and be well-prepared for that final full-compliance test at an accredited test house. With your own chamber, you can considerably reduce the time-to-market. Imagine being able to test whatever you want, whenever you want—no more delays or travelling to external parties. Owning an in-house test chamber lets you control every aspect of testing. Especially for OEMs, this pre-compliant solution is attractive.”

Klaas Pluvier from the KU Leuven Brugge: ”Our pre-compliant lab in Brugge is a place where companies can perform tests during the development stage of products, such as computer peripherals, everyday mass-market electronics, and household appliances. The benefit for companies in this stage is that we are non-accredited as a test lab, so we are allowed to think with the client when a test does not meet the pass and fail criteria of the EMC standard and advise them, something accredited test houses are not allowed to do.”

Upgrading an EMC chamber with new absorbers on old tiles

Can you upgrade an EMC chamber and keep the old, glued ferrite tiles? “It’s possible”, says Uliana Trucchi, one of our technical consultants. “Say you want to replace your old absorbers because you need to meet performances over 1GHz, and you wish to keep the ferrite tiles because they are glued to the chamber’s walls and ceiling. That is exactly what the people from Nemko in Germany asked us for the chamber upgrade in the photo.”

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.
