32、f the product committees) Part 4: Testing and measurement techniques Measurement techniques Testing techniques Part 5: Installation and mitigation guidelines Installation guidelines Mitigation methods and devices Part 6: Generic standards Part 9: Miscellaneous Each part is further subdivided into se
33、veral parts, published either as international standards or as technical specifications or technical reports, some of which have already been published as sections. Others will be published with the part number followed by a dash and a second number identifying the subdivision (example: 61000-6-1).
34、This part is an International Standard which gives immunity requirements and test procedures related to surge voltages and surge currents. EN 61000-4-5:2006 6 ELECTROMAGNETIC COMPATIBILITY (EMC) Part 4-5 : Testing and measurement techniques Surge immunity test 1 Scope and object This part of IEC 610
35、00 relates to the immunity requirements, test methods, and range of recommended test levels for equipment to unidirectional surges caused by overvoltages from switching and lightning transients. Several test levels are defined which relate to different environment and installation conditions. These
36、requirements are developed for and are applicable to electrical and electronic equipment. The object of this standard is to establish a common reference for evaluating the immunity of electrical and electronic equipment when subjected to surges. The test method documented in this part of IEC 61000 d
37、escribes a consistent method to assess the immunity of an equipment or system against a defined phenomenon. NOTE As described in IEC Guide 107, this is a basic EMC publication for use by product committees of the IEC. As also stated in Guide 107, the IEC product committees are responsible for determ
38、ining 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. TC 77 and its sub-committees are prepared to co-operate with product committees in the evaluation of the value of particular
39、immunity tests for their products. This standard defines: a range of test levels; test equipment; test setups; test procedures. The task of the described laboratory test is to find the reaction of the EUT under specified operational conditions, to surge voltages caused by switching and lightning eff
40、ects at certain threat levels. It is not intended to test the capability of the EUTs insulation to withstand high-voltage stress. Direct injections of lightning currents, i.e, direct lightning strikes, are not considered in this standard. 2 Normative references The following referenced documents are
