Applus+ Laboratories
Keystone Compliance, now part of the Applus+ group, is an ISO 17025-accredited EMC testing laboratory operating facilities across Pennsylvania, Michigan, and North Carolina. The lab supports a wide range of industries including medical, military and aerospace, automotive, railway, nuclear, UAV, and consumer electronics. The EMC facility houses 11 test chambers, three of which are large 3-meter semi-anechoic chambers with oversized doors capable of accommodating large items such as vehicles, generators, server racks, drones, and home appliances. Beyond the chambers, the lab maintains multiple ground planes for ESD, indirect lightning, and other non-chamber testing. On-site and in-situ testing capabilities are also available for equipment that cannot be moved. From a technical standpoint, radiated immunity testing reaches up to 200 V/m from 10 kHz to 40 GHz, and radiated emissions testing extends to 40 GHz. ESD testing capabilities go up to 30 kV, surge testing reaches 200 kV / 100 kA, and magnetic field immunity testing is supported up to 100 A/m continuous and 40,000 A/m impulse. Shielding effectiveness testing covers small panels and enclosures up to full buildings and cabling infrastructure, with a dynamic range up to 40 GHz. The full list of EMC capabilities includes radiated and conducted emissions and immunity, ESD, EFT/burst, surge, harmonics, flicker, voltage dips and interrupts, HIRF, indirect lightning, electromagnetic pulse (EMP), shielding effectiveness, FCC certification, CE Mark, military standard testing (MIL-STD-461), DO-160, and country-specific approvals including VCCI (Japan) and KC (South Korea).
