IEC 61786-1:2013提供了用于测量准静态磁场和电场场强的测量仪器指南，这些准静态磁场和电场的频率范围为1 Hz至100 kHz，并带有直流磁场，以评估人体对这些磁场的暴露水平。场源包括以工频运行并产生工频和工频谐波场的设备，以及在本文件频率范围内产生场的设备，包括产生静电场的设备和地球的静电磁场。 本标准涵盖的震级范围为0.1μ；磁场和电场分别为1伏/米到50千伏/米和1毫伏/米到200毫伏/米交流（1毫伏/米到10毫伏/米直流）。当进行超出该范围的测量时，本标准的大部分规定仍将适用，但应特别注意规定的不确定度和校准程序。IEC 61786-1和IEC 61786-2的第一版取代了IEC 61786:1998。第1部分涉及测量仪器，第2部分涉及测量程序。 修订了标准的内容，以便向用户提供最新的实用信息。

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.
