IEC/IEEE 62704的这一部分描述了有限元分析的概念、技术和局限性 单元法（FEM），并规定了验证、验证和测试的模型和程序 FEM用于确定峰值空间平均值时的不确定度评估 在模型或解剖模型中的比吸收率（psSAR）。它建议 提供有关无线通信设备建模的指导，并提供 用于在此类模型或模型中模拟SAR的基准数据。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This part of IEC/IEEE 62704 describes the concepts, techniques, and limitations of the finite element method (FEM) and specifies models and procedures for verification, validation and uncertainty assessment for the FEM when used for determining the peak spatial-average specific absorption rate (psSAR) in phantoms or anatomical models. It recommends and provides guidance on the modelling of wireless communication devices, and provides benchmark data for simulating the SAR in such phantoms or models.All current amendments available at time of purchase are included with the purchase of this document.
