标准摘要
[中文适用范围]: 本部分国际电工委员会(IEC)标准为用于测量准静态磁场和电场的测量仪器提供指导,其频率成分在1 Hz至100 kHz范围内,并包含直流磁场,用于评估人体暴露于这些场时的暴露水平。场的来源包括在工频下运行并产生工频及工频谐波场的设备,以及在本文档频率范围内产生场的设备(包括产生静态场的设备)和地球静态磁场。本标准涵盖的幅度范围分别为:交流磁场0.1 µT至200 mT(直流磁场1 µT至10 T),以及电场1 V/m至50 kV/m。当在此范围之外进行测量时,本标准的大多数规定仍然适用,但应特别注意规定的不确定度和校准程序。具体而言,本标准:定义了术语;确定了场测量仪器规范的要求;指出了校准方法;定义了仪器不确定度的要求;描述了场的一般特征;描述了仪器的操作原理。 [外文原描述]: IEC 61786-1:2013 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 .
