标准摘要
[中文适用范围]: 本部分IEC 61786为测量仪器提供了指导,用于测量准静态磁场和电场的场强,其频率范围在1 Hz至100 kHz之间,以及直流磁场,以评估人体对这些场的暴露水平。 场源包括在电源频率下运行的设备,产生电源频率和电源频率谐波场,以及在本文件频率范围内产生场的设备,包括产生静态场的设备和地球的静态磁场。本标准涵盖的幅度范围为交流磁场0.1 μT至200 mT(直流1 μT至10 T)和电场1 V/m至50 kV/m。 当进行超出此范围的测量时,本标准的多数规定仍然适用,但应特别注意规定的不确定性和校准程序。 具体而言,本标准 - 定义术语; - 确定场强计规范的要求; - 指示校准方法; - 定义仪器不确定性的要求; - 描述场的一般特性; - 描述仪器的操作原理。 注:关于评估人体暴露的测量方法,在IEC 61786-2中描述。 还确定了校准过程中的不确定性来源。关于电场测量,本标准仅考虑在自由空间中某一点(即在场强计和操作者引入之前)或导电表面上方的未扰动电场强度的测量。 本标准主要供技术委员会根据IEC指南108中规定的原则准备标准时使用。技术委员会的责任之一是在适用的情况下,在准备其出版物时使用横向标准。除非在相关出版物中特别引用或包含,否则本横向标准的内容将不适用。 [外文原描述]: IEC 61786-1:2013+AMD1:2024 CSV provides guidance for measuring instruments used to measure the field strength of quasi-static magnetic and electric fields that have a frequency content in the range 1 Hz to 100 kHz and with DC magnetic fields to evaluate the exposure levels of the human body to these fields. Sources of fields include devices that operate at power frequencies and produce power frequency and power frequency harmonic fields, as well as devices that produce fields within the frequency range of this document, including devices that produce static fields, and the earth's static magnetic field. The magnitude ranges covered by this standard are 0,1 μT to 200 mT in AC (1 μT to 10 T in DC) and 1 V/m to 50 kV/m for magnetic fields and electric fields, respectively. When measurements outside this range are performed, most of the provisions of this standard will still apply, but special attention should be paid to specified uncertainty and calibration procedures. The first editions of IEC 61786-1 and IEC 61786-2 replace IEC 61786:1998. Part 1 deals with measuring instruments, and Part 2 deals with measurement procedures. The content of the standard was revised in order to give up-to-date and practical information to the user. It has the status of a horizontal standard in accordance with IEC Guide 108 .
