Tips & Trends for 2025: Inhouse pretesting for OEMs

In-house pretesting is a wise investment that saves time and money. In a series of five posts, our specialists share trends and developments for 2025. This week, Technical Consultant Uliana Trucchi will discuss the future of in-house pretesting for OEMs.

Uliana: “More and more products contain electronics that require testing. Many OEMs use test houses to pretest their products before the final certification. That creates a challenge because test houses are sometimes hard to book quickly, and the out-of-pocket costs pile up. I predict that more and more OEMs will consider in-house pretesting to secure their time-to-market and control costs. And honestly, you do not need to go to a test house for every step in the product development.”

Can certification be done in-house as well? Uliana: “OEMs can self-certify, but you have to be confident and well-prepared with a good correlation between the test executed in your pre-compliant chamber and the fully compliant one at the final certification body, and the investment in a pre-compliant chamber is doable. However, to be sure you correlate correctly, send your products to an external test house occasionally.”

Are in-house pretesting and self-certification options for you? Contact Marc Le Roy, Uliana Trucchi, Vincent van de Vrie, or Hanneke Mertens – van Veen to find out.

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.
