Scope

This part of GB/T 17626 specifies the test requirements and methods for common-mode conducted disturbance immunity of electrical and electronic equipment within the frequency range of 0Hz to 150kHz. The purpose of this section is to establish common and repeatable guidelines for electrical and electronic equipment subjected to common-mode conducted disturbance testing. This section applies to power ports, control/signal ports and communication ports of the device. This standard specifies: - test voltage and current waveforms; - range of test levels; - test equipment; - test arrangement; - test procedures. For some types of ports, such as ports connected to height-balanced lines, additional test provisions are required in the product specification. The provisions of this part are intended to verify the immunity of electronic and electrical equipment to conducted common-mode disturbances such as leakage currents from power line currents and loops in grounding systems. This section does not include the disturbance generated by the 400Hz power system. Since the actual interference caused by these disturbance sources is relatively small (except for industrial environments), professional standardization technical committees should judge and adopt them in product/product standards according to the situation. (See Chapter 4 of this section) The test is not applicable to short cable ports with a connection length of less than 20m. The tests in this section apply to electrical and electronic equipment or systems. The same applies to modules or subsystems if the rated power of the EUT (equipment under test) is greater than the capacity of the test generator required by this part 6. The harmonics and interharmonics of the AC power port, and the differential mode immunity test of the power signal are not included in this part, and are included in GB/T 17626.13. Disturbance immunity tests for intentional electromagnetic emissions are also not included in this section, and are included in GB/T 17626.6. Some ITU recommendations, such as: K17, K20 and K21, have specified similar tests, but they apply to communication ports and power line induction in the frequency range of AC mains and electrified railways. Professional standardization technical committees should consider applying the above ITU recommendations when formulating product standards.
