CISPR 24:20 10适用于CISPR 22中定义的信息技术设备（ITE）。本出版物的目的是建立提供足够水平的固有抗扰度的要求，以便设备在其环境中按预期运行。该出版物定义了其范围内设备在连续和瞬态传导和辐射干扰（包括静电放电（ESD））方面的抗扰度测试要求。定义了测量ITE的程序，并规定了在0 Hz至400 GHz频率范围内为ITE制定的限值。对于特殊的环境条件，可能需要特殊的缓解措施。由于测试和性能评估的考虑，一些测试被指定在定义的频带或在选定的频率。满足这些频率要求的设备被认为满足了从0 Hz到400 GHz的整个频率范围内电磁现象的要求。为所考虑的每个端口指定了测试要求。第二版取消并取代了1997年出版的第一版及其修正案1（2001）和2（2002）。这是一次技术修订。与上一版相比，此版本包括以下重大技术变更:-更新了注明日期的参考文献；-删除了使用4%步长进行连续抗扰度测试的选项；-修订电话设备附件A，包括测量扬声器/免提设备解调的方法；-列入与DSL设备有关的新附件。2011年6月更正的内容已纳入本副本。

CISPR 24:2010 applies to information technology equipment (ITE) as defined in CISPR 22. The object of this publication is to establish requirements that will provide an adequate level of intrinsic immunity so that the equipment will operate as intended in its environment. The publication defines the immunity test requirements for equipment within its scope in relation to continuous and transient conducted and radiated disturbances, including electrostatic discharges (ESD). Procedures are defined for the measurement of ITE and limits are specified which are developed for ITE within the frequency range from 0 Hz to 400 GHz. For exceptional environmental conditions, special mitigation measures may be required. Owing to testing and performance assessment considerations, some tests are specified in defined frequency bands or at selected frequencies. Equipment which fulfils the requirements at these frequencies is deemed to fulfil the requirements in the entire frequency range from 0 Hz to 400 GHz for electromagnetic phenomena. The test requirements are specified for each port considered. This second edition cancels and replaces the first edition published in 1997, and its Amendments 1(2001) and 2(2002). It is a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- dated references updated;
- option of using a 4 % step size for continuous conducted immunity test deleted;
- revision of Annex A for telephony equipment including methodology for measuring the demodulation from a speaker/hands free device;
- inclusion of new annex related to DSL equipment.The contents of the corrigendum of June 2011 have been included in this copy.
