与人体暴露于电场、磁场和电磁场有关的接触电流评估

[中文适用范围]： 本文件@是一份技术报告@，提供了与人体暴露于电场、磁场和电磁场相关的接触电流评估的一般信息。当人体与未带电的导电物体接触时，由于对物体的电和/或磁感应，该物体暴露于处于不同电势的电场和/或磁场中，在此上下文中，接触电流发生。这与处理与导电物体的带电部分接触的电气安全问题不同。参考国际 EMF 指南 [1]-[4] 1 @ 本文件中涵盖的接触电流频率范围为直流电至 110 MHz@，并且仅涵盖稳态（连续）接触电流。不包括在与物体接触之前可能立即发生的瞬态接触电流（火花放电）。 [外文原描述]： IEC/TR 62905:2018(E) is a Technical Report. Provides general information on the assessment of contact current related to human exposure to electric, magnetic and electromagnetic fields. The contact currents in this context occur when a human body comes into contact with a not electrified conductive object exposed to an electric and/or magnetic field at a different electric potential owing to electric and/or magnetic induction to the object. This is distinguished from the issue of electrical safety where contact with live parts of a conductive object is dealt with. In reference to the international EMF guidelines, the frequency range of contact current covered in this document is direct current to 110 MHz, and only steady-state (continuous) contact currents are covered. Transient contact currents (spark discharges) which may occur immediately before the contact with the object are not covered.
