If it’s affected by vibration, we can test it. If it shakes, we can measure it. The analytics we generate are critical to engineer solutions for vibration stabilization and seismic restraint. We were the first organization to gain independent, IAS Accreditation as a Product Certification Agency for Special Seismic Certification. Plus, we provide IBC Certification (seismic and wind) for Fortune 500 manufacturers of HVAC, power generation, medical equipment and fire protection systems.
