Electromagnetic Compatibility — Testing and Measurement Techniques — Immunity to Conducted Disturbances, Induced by Radio-frequency Fields 1 Scope This part of GB/T 17626 relates to the conducted immunity requirements of electrical and electronic equipment to electromagnetic disturbances coming from intended radio-frequency transmitters in the frequency range 150 kHz up to 80 MHz. Equipment not having at least one conducting wire and/or cable (such as mains supply, signal line or earth connection) which can couple the equipment to the disturbing RF fields is excluded from the scope of this publication. Note 1: Test methods are defined in this part of GB/T 17626 to assess the effect that conducted disturbing signals, induced by electromagnetic radiation, have on the equipment concerned. The simulation and measurement of these conducted disturbances are not adequately exact for the quantitative determination of effects. The test methods defined are structured for the primary objective of establishing adequate repeatability of results at various facilities for quantitative analysis of effects. The object of this standard is to establish a common reference for evaluating the functional immunity of electrical and electronic equipment when subjected to conducted disturbances induced by RF fields. The test method documented in this part of IEC 61000 describes a consistent method to assess the immunity of an equipment or system against a defined phenomenon. Note 2: As described in GB/Z 18509[1], this standard is a basic EMC publication for use by relevant product committees. As also stated in GB/Z 18509[1], the product committees are responsible for determining whether this immunity test standard should be applied or not, and if applied, they are responsible for determining the appropriate test levels and performance criteria. The National Technical Committee on Electromagnetic Compatibility of Standardization Administration of China (SAC/TC 246) and its sub-committees cooperate with relevant product committees for standardization to evaluate test levels and performance criteria for specific immunity tests on their products. 2 Normative References The following referenced documents are indispensable for the application of this document.
