人体暴露于电场、磁场和电磁场相关的接触电流评估

[中文适用范围]： 本文件为技术报告，提供了关于人体暴露于电场、磁场和电磁场时接触电流评估的一般信息。本文中的接触电流是指当人体接触到未通电但因电场或磁场或两者感应而具有不同电位的导电物体时产生的电流。这与电气安全问题不同，后者涉及与导电物体带电部分的接触。 参考国际EMF指南，本文件涵盖的接触电流频率范围为直流至110 MHz，仅涵盖稳态（连续）接触电流。不涵盖在接触物体之前可能发生的瞬态接触电流（火花放电）。 [外文原描述]： IEC TR 63167:2024 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC TR 63167:2024 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 conductive object that is non-electrified but exposed to an electric field or magnetic field or both at a different electric potential owing to electric 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 DC to 110 MHz, and only steady-state (continuous) contact currents are covered. Transient contact currents (spark discharges) which can occur immediately before the contact with the object are not covered.
