CISPR 18-2:20 10（E）是一份技术报告，适用于可能对无线电接收造成干扰的架空电力线和高压设备的无线电噪声。覆盖的频率范围为0.15 MHz至300 MHz。推荐了建立电力线和设备无线电噪声场限值的一般程序，以及作为示例的典型值和测量方法。限制条款集中在低频和中频段，只有在这些频段，根据既定惯例，有充分的证据可用。没有给出在30MHz至300MHz频带中保护无线电接收的限制的示例，因为该频带中的测量方法和问题的某些其他方面尚未完全解决。现场测量和服务经验表明，频率高于300兆赫的电力线的噪音水平非常低，不太可能对电视接收造成干扰。计算作为示例给出的限制值，以便在通常可能遇到的最不利条件下，在用于a.m.广播的无线电频带中的适当发射机的公认服务区域的边界处对广播的接收提供合理程度的保护。这些限值旨在为线路的规划阶段提供指导，并在施工后和使用寿命期间根据国家标准或其他规范检查线路的性能。用于检查是否符合限度的测量仪器和方法应符合相应的CISPR规范，如e。g.基本标准系列CISPR 16。这第二版取消并取代了1986年出版的第一版。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:-虽然CISPR 18-2的第一版仅考虑了用于建立从高压架空电力线发出的横向无线电噪声场的标准分布的直接距离D0，-该第二版现在还允许将横向距离y0用于这些目的。以这种方式，它允许进行现场测量并简化记录和使用在横向距离y处获得的测量数据，该横向距离y倾斜于具有高悬挂塔的现代HV和UHV架空电力线结构的路径。

CISPR 18-2:2010(E), which is a technical report, applies to radio noise from overhead power lines and high-voltage equipment which may cause interference to radio reception. The frequency range covered is 0,15 MHz to 300 MHz. A general procedure for establishing the limits of the radio noise field from the power lines and equipment is recommended, together with typical values as examples, and methods of measurement. The clause on limits concentrates on the low frequency and medium frequency bands and it is only in these bands where ample evidence, based on established practice, is available. No examples of limits to protect radio reception in the frequency band 30 MHz to 300 MHz have been given, as measuring methods and certain other aspects of the problems in this band have not yet been fully resolved. Site measurements and service experience have shown that levels of noise from power lines at frequencies higher than 300 MHz are so low that interference is unlikely to be caused to television reception. The values of limits given as examples are calculated to provide a reasonable degree of protection to the reception of broadcasting at the boundary of the recognized service areas of the appropriate transmitters in the radio frequency bands used for a.m. broadcasting, in the least favourable conditions likely to be generally encountered. These limits are intended to provide guidance at the planning stage of the line and national standards or other specifications against which the performance of the line may be checked after construction and during its useful life. The measuring apparatus and methods used for checking compliance with limits should comply with the respective CISPR specifications, as e.g. the basic standards series CISPR 16. This second edition cancels and replaces the first edition published in 1986. It is a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- while the first edition of CISPR 18-2 only considered the direct distance D0 for the establishment of standard profiles for the lateral radio noise field emanating from HV overhead power lines,
- this second edition now also allows for use of the lateral distance y0 for these purposes. This way it allows for conduction of on-site measurements and simplified recording and use of measurement data obtained at lateral distances y slant to the pathway of modern HV and UHV overhead power line constructions with tall suspension towers.
