标准摘要
[中文适用范围]： CISPR TR 16-4-4:2025 是一份技术报告，它基于IEC无线电服务数据库（RSD）的数据以及相关概率因子输入值的估计，建立了CISPR用于计算无线电服务保护限值的模型。这是在制定无线电频谱中干扰限值过程中的一部分，用于出版物中包含的发射要求。应用本文件可得出特定干扰现象和所考虑产品或产品类型相关的频率依赖性限值，从而在CISPR限值规范程序中建立技术基础。注：非技术参数和术语，若被认为可能影响限值并包含在IEC出版物中，则不在模型中进行考虑（另见第4.6.5.3条）。本第三版取消并替代了2007年发布的第二版、2017年的第一版修订和2020年的第二版修订。本版为技术性修订版。与前一版相比，本版包括以下重大技术更改：a) 对限值计算模型进行了全面修订；b) 有关投诉统计的内容从本文件中移除，并作为单独文件发布（CISPR TR 16-4-6）；c) 应用案例/理由从模型中分离，并将在另一份待起草的文件中处理。 [外文原描述]： CISPR TR 16-4-4:2025 which is a Technical Report, establishes the CISPR model for the calculation of limits for the protection of radio services, based on data from the IEC Radio Services Database (RSD) and estimations of the input values for related probabilistic factors. This is part of the process of the derivation of disturbance limits in the radio frequency spectrum for use in publications containing emission requirements Application of this document leads to a frequency dependent limit result for a particular disturbance phenomenon and the considered product or product type establishing the technical basis in the CISPR limit specification procedure. NOTE Non-technical parameters and terms that can be considered to influence a limit for inclusion in IEC publications are excluded from the modelling (see also Clause 4.6.5.3). This third edition cancels and replaces the second edition published in 2007, Amendment 1:2017 and Amendment 2:2020. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) full revision of the limit calculation model; b) the content on statistics of complaints was taken from this publication and published as separate document (CISPR TR 16-4-6); c) application cases/rationales were separated from the model and will be handled in another document to be drafted.
