The lab provides EMC compliance testing to EN, IEC, CISPR, FCC, and MIL-STD standards, serving manufacturers across a broad range of industries.
EMC emissions standards covered include EN 55011, EN 61000-6-4, IEC 61000-6-4, IEC CISPR 11, and ANSI C63.4. Immunity testing spans the full IEC/EN 61000-4 series including -4-2 (ESD), -4-3 (radiated immunity), -4-4 (EFT/burst), -4-5 (surge), -4-6 (conducted immunity), -4-8 (power frequency magnetic field), -4-9 (pulse magnetic field), -4-10 (damped oscillatory magnetic field), -4-11 (voltage dips and interruptions), -4-12 (ring wave), -4-13 (harmonics and inter-harmonics), -4-16 (conducted disturbances in the frequency range 0 Hz to 150 kHz), and -4-29 (voltage dips on DC ports). Military EMC testing is performed to MIL-STD-461 revisions E, F, and G. Clark Testing also has over 25 years of experience supporting nuclear power industry equipment qualification (EQ) programs to NRC Regulatory Guide 1.180 and EPRI TR-102323, as well as railway EMC testing to IEC 62236 and EN 50121 series standards.
Industries served include rail and transit, military and defense, aerospace, nuclear and power generation, telecom, automotive, marine, medical, space and satellite, robotics, and battery. In addition to EMC, Clark Testing offers a broad portfolio of other services including MIL-STD-810 environmental testing, vibration, seismic, structural and load testing, dynamometer testing, analytical chemistry, and failure analysis.
