Specification for radio disturbance and immunity measuring apparatus and methods - Part 2-4: Methods of measurement of disturbances and immunity - Immunity measurements

This technical specification establishes detailed requirements and methods for testing equipment to ensure its resilience against electromagnetic disturbances. It specifically addresses the procedures for conducting immunity tests on electrical and electronic products. The document outlines the necessary configuration of test facilities and instrumentation to guarantee accurate and repeatable measurement results. It covers various coupling methods used to introduce disturbance signals into the device under test. The scope includes defining performance criteria and test levels applicable to different types of equipment operating in typical industrial, commercial, and residential environments. Strict adherence to these guidelines is essential for manufacturers and testing laboratories to verify compliance with relevant electromagnetic compatibility regulations. The text provides guidance on calibrating measurement apparatus and interpreting data obtained during immunity assessments. By following the outlined methodologies, organizations can effectively evaluate the robustness of their products against external electromagnetic interference. This approach ensures that devices function reliably in their intended electromagnetic environment without malfunctioning or degrading performance due to external influences. The document serves as a foundational reference for designing, manufacturing, and certifying compliant electronic systems.
