IEC 62369-1:2008介绍了人体暴露于电子物品监控（EAS）、射频识别（RFID）和类似应用中所用设备产生的电磁场（EMF）的评估程序。它采用分阶段的方法来促进合规性评估。第一阶段（第1阶段）是针对适当衍生参考值的简单测量。第二阶段是一系列更复杂的测量或计算，再加上分析技术。第3阶段需要详细的建模和分析，以便与基本限制进行比较。在评估任何设备时，可能会使用最适合暴露情况的方法。在编写本国际标准时，电子物品监控、射频识别和类似系统通常不会在低于1Hz或高于10GHz的频率下运行。 EMF暴露指南和标准可以涵盖更广泛的频率范围，因此，在评估程序中包括对所需范围的澄清。本文件涵盖的设备通常具有非均匀场模式。通常，这些设备的场强会随着距离的增加而迅速降低，并在电场和磁场之间关系不恒定的近场条件下工作。附件A中详细说明了这一点，以及不同设备类型的典型暴露条件。附件B包含全面信息，有助于对暴露情况进行数值模拟。它包括均质和解剖模型以及组织的电特性。IEC 62369-1:2008不包括限制。限值可从单独发布的人体接触指南中获得。 不同地区可能适用不同的指南和限值。与指南相关联的通常是更宽频率范围内和多个暴露源的求和方法。应使用这些。附录C中包含了一种简化的多源求和方法。必须谨慎使用，因为它过于简单，会高估暴露量；然而，当不同评估的结果以不同的度量单位表示，且不兼容时，本指南非常有用。不同的国家和地区对评估中的不确定性有不同的处理指南。附件D提供了关于两种最常用方法的信息。

IEC 62369-1:2008 presents procedures for the evaluation of human exposure to electromagnetic fields (EMFs) from devices used in electronic article surveillance (EAS), radio frequency identification (RFID) and similar applications. It adopts a staged approach to facilitate compliance assessment. The first stage (Stage 1) is a simple measurement against the appropriate derived reference values. Stage 2 is a more complex series of measurements or calculations, coupled with analysis techniques. Stage 3 requires detailed modelling and analysis for comparison with the basic restrictions. When assessing any device, the most appropriate methodfor the exposure situation may be used. At the time of writing this International Standard, electronic article surveillance, radio frequency identification and similar systems do not normally operate at frequencies below 1 Hz or above 10 GHz. EMF exposure guidelines and standards can cover a wider range of frequencies, so clarification on the required range is included as part of the evaluation procedures. The devices covered by this document normally have non-uniform field patterns. Often these devices have a very rapid reduction of field strength with distance and operate under near-field conditions where the relationship between electric and magnetic fields is not constant. This, together with typical exposure conditions for different device types, is detailed in Annex A. Annex B contains comprehensive information to assist with numerical modelling of the exposure situation. It includes both homogeneous and anatomical models as well as the electrical properties of tissue. IEC 62369-1:2008 does not include limits. Limits can be obtained from separately published human exposure guidelines. Different guidelines and limit values may apply in different regions. Linked into the guidelines are usually methods for summation across wider frequency ranges and for multiple exposure sources. These shall be used. A simplified method for summation of multiple sources is contained in Annex C. This has to be used with care as it is simplistic and will overestimate the exposure; however it is useful as a guide, when the results of different evaluations are in different units of measure which are not compatible. Different countries and regions have different guidelines for handling the uncertainties from the evaluation. Annex D provides information on the two most common methods.
