IEC 61786-2:20 14提供了频率含量在1 Hz至100 kHz范围内的准静态磁场和电场以及DC磁场的测量要求，以评估人体对这些磁场的暴露水平。具体来说，本标准给出了建立测量程序的要求，以实现与人体暴露相关的既定目标。由于来自各种环境中的源的场的特性的差异，例如频率内容、时间和空间变化、极化和幅度，以及测量目标的差异，特定的测量过程在各种环境中将是不同的。场源包括在工频下工作并产生工频和功率-频率谐波场，以及产生与电源频率无关的场的装置、直流输电和地磁场。该标准涵盖的震级范围为交流电0.1微特斯拉至200毫特斯拉（直流为1微特斯拉至10特斯拉），电场为1 V/m至50 kV/m。当进行超出此范围的测量时，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。可以用该标准测量的场源的示例包括: -在工频(50/60Hz)下工作并产生工频和谐波场的设备(例如:电力线、电器)； -产生与电源频率无关的场的设备。（例如:电气化铁路（DC至20kHz）； -商用飞机(400Hz)、感应加热器(高达100kHz)和电动车辆)； -以及产生静磁场的设备:MRI、直流电力线、直流焊接、电解、磁铁、电炉等。直流电流通常由转换器产生，也会产生交流分量（工频谐波），应进行评估。当EMF产品标准可用时，应使用这些产品标准。关于电场测量，本标准仅考虑空间点（即引入场计和操作员之前的电场）或导电表面上的未扰动电场强度的测量。还确定了测量过程中不确定度的来源，并就如何组合它们以确定总测量不确定度提供了指导。

IEC 61786-2:2014 provides requirements for the measurement of quasi-static magnetic and electric fields that have a frequency content in the range 1 Hz to 100 kHz, and DC magnetic fields, to evaluate the exposure levels of the human body to these fields. Specifically, this standard gives requirements for establishing measurement procedures that achieve defined goals pertaining to human exposure. Because of differences in the characteristics of the fields from sources in the various environments, e.g. frequency content, temporal and spatial variations, polarization, and magnitude, and differences in the goals of the measurements, the specific measurement procedures will be different in the various environments. 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 independent of the power frequency, and DC power transmission, and the geomagnetic field. The magnitude ranges covered by this standard are 0,1 micro-Tesla to 200 mili-Tesla for AC (1 micro-Tesla to 10 Tesla for DC) for magnetic fields, and 1 V/m to 50 kV/m for electric fields. When measurements outside this range are performed, most of the provisions of this standard will still apply, but special attention should be paid to the specified uncertainty and calibration procedures. Examples of sources of fields that can be measured with this standard include:
- devices that operate at power frequencies (50/60 Hz) and produce power frequency and power-frequency harmonic fields (examples: power lines, electric appliances.);
- devices that produce fields that are independent of the power frequency.(Examples: electric railway (DC to 20 kHz);
- commercial aeroplanes (400 Hz), induction heaters (up to 100 kHz), and electric vehicles);
- and devices that produces static magnetic fields: MRI, DC power lines, DC welding, electrolysis, magnets, electric furnaces, etc. DC currents are often generated by converters, which also create AC components (power frequency harmonics), which should be assessed. When EMF products standards are available, these products standards should be used. With regard to electric field measurements, this standard considers only the measurement of the unperturbed electric field strength at a point in space (i.e. the electric field prior to the introduction of the field meter and operator) or on conducting surfaces. Sources of uncertainty during measurements are also identified and guidance is provided on how they should be combined to determine total measurement uncertainty.
