多年来，已经制定了许多电磁兼容性测量和控制标准。其中许多与特定类别的装置有关，如接收器、发射器、附带辐射装置等。在确定限值时，有必要将用于确定是否符合给定限值的测量技术与被控制装置实际运行的现场条件联系起来。本标准的目的是，至少为参考目的，提出一套可能普遍适用的建议限值。 本文件未设定具体限制。它提出了制定限制的理由，并推荐了一组代表当前实践的限制。在实践中，这些限制可根据具体情况在特定应用中进行调整。本文件不考虑工业、科学和医学（ISM）设备的限制，特别是使用无线电频率作为其操作的主要部分。作为制定限制的一部分，应考虑以下参数: 1） 二者的一般性质- 人工和自然环境噪声 2） 了解通常用于测量无线电噪声的设备及其特性，这将有助于从业者为特定应用选择此类设备和相关测量技术3）选择发射和抗扰度的一致限值的原理，（敏感性）根据各种环境约束（良好工程实践），这些实践适用于单个设备以及各种尺寸的系统，如果正确应用，将为获得系统内和系统间兼容性提供指导。 本标准组织如下:第2节参考仪器和测量方法，第4节描述环境无线电噪声，第4节描述测量参数的选择。第6节讨论限制设置，第6节是参考文献列表。

Over the years many electromagnetic compatibility measurement and control standards have been developed. Many of these are of concern to particular classes of devices such as receivers, transmitters, incidental radiation devices, etc. In establishing limits, it is necessary to relate the measurement technique used to determine compliance with a given limit to the field conditions under which the device being controlled will actually operate. The purpose of this standard is to set forth, at least for reference purposes, a suggested set of limits which may find general application. This document does not set specific limits. It presents a rationale for developing limits and recommends a set of limits that are representative of current practice. In practice these limits1 may be adjusted in particular applications as circumstances dictate. This document does not consider limits for industrial, scientific, and medical (ISM) equipment which specifically uses radio frequencies as a major part of its operation. As part of the development of limits, the following parameters should be considered: 1) The general properties of both man-made and natural environmental noise 2) An understanding of the devices commonly used for measurement of radio noise and their properties, which will assist the practitioner in selecting such equipment and associated measurement techniques for the particular application 3) The rationale that can be used in selecting a consistent set of limits for emission and immunity, (susceptibility) subject to various environmental constraints (good engineering practice) These practices are intended to be applicable to individual equipment as well as systems of various sizes and, if properly applied, will provide guidance for obtaining both intrasystem and intersystem compatibility. This standard is organized as follows: Section 2 references instrumentation and measurements methods, Section contains a list of definitions, Section 4 describes environmental radio noise, and Section describes the selection of measurement parameters. Section 6 discusses limit setting, and Section is a list of references.
