CISPR 16-4-2:2011+A1:2014+A2:2018是EMC基本出版物。它规定了在确定是否符合CISPR干扰限值时应用测量仪器不确定度（MIU）的方法。当对结果和结论的解释受到测试期间使用的测量仪器的不确定性的影响时，该材料也与任何EMC测试相关。第二版包括关于干线和通信端口上的传导干扰测量方法以及关于使用30 MHz至1000 MHz和1 GHz至18 GHz范围内的FAR的辐射干扰测量方法的重要技术补充。附件包含用于提供在生成主文件中显示的CISPR值时发现的MIU量的背景材料，因此为那些需要关于MIU的初始和进一步信息以及如何将测量链中的单个不确定性纳入计算。然而，附件不是教程或用户手册，也不是在进行不确定性计算时复制的。为此，可以使用参考书目中所示的参考文献或其他广泛认可的文献。CISPR 16-1系列给出了测量仪器规格，而CISPR 16-2系列涵盖了测量方法。CISPR 16-3中给出了关于CISPR和无线电干扰的更多信息和背景。CISPR 16-4系列的其他部分包含关于一般不确定性、统计和极限建模的更多信息。该合并版本由第二版（2011年）及其勘误表（2013年）、修正案1（2014年）和修正案2（2018年）组成。因此，除本出版物外，无需下令修订。

CISPR 16-4-2:2011+A1:2014+A2:2018 is a basic EMC publication. It specifies the method of applying Measurement Instrumentation Uncertainty (MIU) when determining compliance with CISPR disturbance limits. The material is also relevant to any EMC test when interpretation of the results and conclusions reached will be impacted by the uncertainty of the measurement instrumentation used during testing. This second edition includes significant technical additions about methods of conducted disturbance measurements on mains and communication ports and about methods of radiated disturbance measurements using a FAR in the ranges of 30 MHz to 1 000 MHz and of 1 GHz to 18 GHz. The annexes contain the background material used in providing the amount of MIU found in generating the CISPR values shown in the main document and hence provide valuable background material for those needing both initial and further information on MIU and how to take individual uncertainties in the measurement chain into account. The annexes, however, are not intended to be a tutorial or user manual or to be copied when making uncertainty calculations. For that purpose, the references shown in the bibliography, or other widely recognized documents, may be used. Measurement instrumentation specifications are given in the CISPR 16-1 series, while the methods of measurement are covered in the CISPR 16-2 series. Further information and background on CISPR and radio disturbances is given in CISPR 16-3. The other parts of the CISPR 16-4 series contain further information on uncertainties in general, statistics and limit modelling. This consolidated version consists of the second edition (2011) and its corrigendum (2013), its amendment 1 (2014) and its amendment 2 (2018). Therefore, no need to order amendment in addition to this publication.
