Electrical and EMC testing services evaluate parts and products for electromagnetic compatibility (EMC), electromagnetic interference (EMI), radio frequency interference (RFI), dielectric properties, conductivity, electrostatic discharge (ESD), insulation resistance, and other electrical characteristics. Companies offer services such as research and development, simulation, in-line and in-process testing, product comparison, and certification. Electrical and EMC testing services that inspect in-service or newly fabricated products perform environmental exposure testing, dynamics testing, non-destructive testing (NDT), visual inspection, chemical analysis or structural material testing. Some companies design, install and/or operate data acquisition systems or test instrumentation in on-site facilities or off-site labs. Others provide test fixtures, equipment, and facilities for specific applications. Test panel and sample preparation services simulate the effects of products such as paints, coatings, and lubricants upon test samples.
