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。此类接触电流发生在人体接触导电物体时，该物体因电场或磁场或两者的感应而带电但未通电。与电气安全中处理带电部件接触的问题不同。 参考国际EMF指南，本文档涵盖的接触电流频率范围为DC至110 MHz，仅涵盖稳态（连续）接触电流。不涵盖接触物体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 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.
