  6.1.4 Verification of the characteristics of the test generator中,
原先内容:“The waveform characteristics shall be verified at the EUT port (port by port) of each CDN used for the immunity test, or directly at the output of the test generator if no CDN is to be used.”
更新内容:”The waveform characteristics shall be verified directly at the output of the test generator with open circuit and short circuit load impedance.”

6.2 Specifications of the coupling/decoupling network中,
原先内容:”The coupling/decoupling network (CDN) provides both the ability to apply the test voltage in either common (for both generators) or differential (only 100 kHz, 1 MHz) mode to the mains, signal and control ports of the EUT (equipment under test), and prevents test voltage from affecting and auxiliary equipment needed to perform the test. The waves shall be within the tolerances of 6.1.1 or 6.1.2 at the EUT port of the CDN. Verifications shall be made port by port. E.g. 3 phase CDN: L1 to PE, L2 to PE, L3 to PE, N to PE.
更新内容:” The coupling/decoupling network (CDN) provides ... Verifications shall be made port by port with the short circuit test load impedance of 0.1 Ohms, e.g. 3-phase CDN: L1 to PE, L2 to PE, L3 to PE, N to PE.”

标准修改内容为检验设备自校过程的变化,对于所检测的电磁兼容参数没有发生变化。
