RheinTech Laboratories

About

Rhein Tech Laboratories is an EMC/EMI testing, mitigation, and certification laboratory located in Herndon, Virginia, just outside Washington, D.C. In operation since 1988, the lab serves a broad client base — from first-time entrepreneurs to seasoned engineering teams at global companies — helping them navigate EMC design challenges and international regulatory requirements to achieve the shortest path to market. Rhein Tech's services span several core areas. Their EMI/EMC testing covers commercial, industrial/scientific/medical (ISM), and military/aerospace equipment. For military and aerospace clients, they perform testing to MIL-STD requirements. The lab also offers shielding effectiveness and RF transparency testing on various materials, types, and sizes — useful for manufacturers evaluating enclosure materials, gaskets, coatings, and other shielding solutions. A more specialized capability is Radar Cross-Section (RCS) measurements, a less common service among EMC labs. A key differentiator for Rhein Tech is their emphasis on PCB design review and EMI mitigation. Rather than simply reporting pass/fail results, their engineers work with clients to identify design issues and recommend cost-effective solutions that can be incorporated into production. This approach helps eliminate costly last-minute redesigns and launch delays — a service that has earned them strong client loyalty and top marks in customer surveys for technical competency, turnaround time, and communications. On the certification side, Rhein Tech handles FCC certification, self-declaration support, and international approvals in over 100 countries. They also operate Rhein Tech Systems, a division focused on bringing new technology concepts to life with innovative solutions.
