This part of GB/T 17626 specifies the immunity requirements, test methods and recommended test level range for equipment to unipolar surge (shock) caused by switching and lightning transient overvoltages, and specifies the requirements for different environments and installations. Several test levels in the state. The requirements set out in this standard apply to electrical and electronic equipment. The purpose of this standard is to establish a common benchmark for evaluating the performance of electrical and electronic equipment when subjected to surges (shocks). This standard specifies a consistent test method to assess the immunity of equipment or systems to specified phenomena. This standard specifies: - the range of test levels; - test equipment; - test configuration; - test procedures. The task of the laboratory test is to find out the response of the equipment to the surge (impulse) voltage with a certain level of hazard generated by the switch or lightning when it is working under the specified working condition. This section does not test the insulation capability of the EUT withstanding high voltage. This section does not consider the direct injection of lightning current for direct lightning strikes.
