GB/T 33014.4-2025 in English

This standard outlines a method for testing the immunity of electrical and electronic components in road vehicles to narrowband radiated electromagnetic energy. It specifically focuses on the technique known as the wire harness excitation method. The procedure described is designed to evaluate how well these components can withstand electromagnetic interference under controlled conditions. The test method provides guidelines for setting up the testing environment, conducting the experiments, and interpreting the results. It ensures consistency in the evaluation process and supports the development of reliable and robust vehicle systems. The standard is structured to facilitate the application of standardized testing procedures across different manufacturers and industries.
