前言:这是CSA IEC 61000-4-3第三版，电磁兼容性（EMC）-第4-3部分:测试和测量技术-辐射、射频、电磁场抗扰度测试，这是对同名IEC（国际电工委员会）标准61000-4-3（3:2006版，合并修订件1:2007和修订件2:2010）的采用，未经修改。它取代了2007年发布的前一版本，即CAN/CSA-CEI/IEC 61000-4-3（采用IEC 61000-4-3:2006）。本标准的制定符合加拿大标准委员会对加拿大国家标准的要求。CSA集团已将其作为加拿大国家标准发布。 范围和目的:IEC 61000的本部分适用于电气和电子设备对辐射电磁能的抗扰度要求。它确定了测试级别和所需的测试程序。本标准的目的是为评估电气和电子设备在受到辐射射频电磁场时的抗扰度建立一个通用参考。IEC 61000本部分中记录的试验方法描述了评估设备或系统对特定现象的抗扰度的一致方法。注1:如IEC指南107所述，这是供IEC产品委员会使用的基本EMC出版物。 正如指南107中所述，IEC产品委员会负责确定是否应采用该抗扰度测试标准，如果采用，则负责确定适当的测试水平和性能标准。TC 77及其下属委员会准备与产品委员会合作，评估其产品特定抗扰度测试的价值。本部分涉及与任何源射频电磁场防护相关的抗扰度试验。特别注意防止数字无线电话和其他射频发射设备的射频发射。注2:本部分规定了用于评估电磁辐射对相关设备影响的试验方法。 电磁辐射的模拟和测量对于效应的定量测定不够精确。定义的试验方法的主要目的是在各种试验设施中建立足够的结果重复性，以便对影响进行定性分析。本标准是一种独立的试验方法。其他试验方法不得用作声称符合本标准的替代方法。

Preface:This is the third edition of CSA IEC 61000-4-3,Electromagnetic compatibility (EMC) — Part 4-3: Testing and measurement techniques — Radiated, radio-frequency, electromagnetic field immunity test, which is an adoption without modification of the identically titled IEC (International Electrotechnical Commission) Standard 61000-4-3 (edition 3:2006 consolidated with Amendment 1:2007 and Amendment 2:2010. It supersedes the previous edition, published in 2007 as CAN/CSA-CEI/IEC 61000-4-3 (adopted IEC 61000-4-3:2006).This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.Scope and object:This part of IEC 61000 is applicable to the immunity requirements of electrical and electronic equipment to radiated electromagnetic energy. It establishes test levels and the required test procedures.The object of this standard is to establish a common reference for evaluating the immunity of electrical and electronic equipment when subjected to radiated, radio-frequency electromagnetic 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 1 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 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. TC 77 and its sub-committees are prepared to co-operate with product committees in the evaluation of the value of particular immunity tests for their products.This part deals with immunity tests related to the protection against RF electromagnetic fields from any source.Particular considerations are devoted to the protection against radio-frequency emissions from digital radiotelephones and other RF emitting devices.NOTE 2 Test methods are defined in this part for evaluating the effect that electromagnetic radiation has on the equipment concerned. The simulation and measurement of electromagnetic radiation is not adequately exact for quantitative determination of effects. The test methods defined are structured for the primary objective of establishing adequate repeatability of results at various test facilities for qualitative analysis of effects.This standard is an independent test method. Other test methods may not be used as substitutes for claiming compliance with this standard.
