Abstract:In order to ensure the accuracy and consistency of electromagnetic interference field strength testing results among various electromagnetic environment testing laboratories, evaluate the laboratory's electromagnetic environment testing ability, more accurately evaluate the potential impact of electromagnetic radiation on human health, and the adverse effects on instruments, equipment, and environmental facilities, starting from the purpose of electromagnetic environment testing laboratory comparison, the architecture and principle of the electromagnetic environment interference field strength testing system were studied. Combined with the electromagnetic environment interference field strength testing method, the comparison between electromagnetic environment testing laboratories was designed, and a scheme for comparison between electromagnetic environment testing laboratories, as well as statistical methods and evaluation principles for comparison test results, were proposed. Through practical application, the comparison process of electromagnetic environment interference field strength testing between laboratories was realized, This provides a reference for conducting inter laboratory comparisons in electromagnetic environment testing laboratories.
