本国际标准规定了使用时域有限差分法（FDTD）和有限元法（FEM）评估峰值和空间平均功率密度的计算程序，该功率密度与人体暴露在6GHz和300GHz之间的设备中的头部或身体有关。它适用于距离小于等于200mm的具有辐射结构的设备。这包括但不限于手机、平板电脑和可穿戴设备。本标准对大多数人在正常使用这些设备期间头部或身体暴露的功率密度进行了保守估计。

This International Standard specifies computational procedures using Finite-Difference Time-Domain (FDTD) and Finite Element Methods (FEM) to assess the peak and spatial-averaged power density relevant to the human exposure of the human head or body from devices operating between 6 GHz and 300 GHz. It applies to devices with radiating structures at distances up to and including 200 mm. This includes but is not limited to mobile phones, tablets, and wearables. This standard provides a conservative estimate of the power density of the exposure of the head or body for a significant majority of persons during normal use of these devices.
