标准摘要
[中文适用范围]： 本部分IEC 62209规定了在简化的人体头部或身体模型内，由射频（RF）发射设备引起的峰值空间平均比吸收率（psSAR）的可重复测量协议和测试程序，并规定了测量不确定度。提供了使用基于矢量测量的系统进行psSAR评估的要求。此类系统根据本文对测量系统、校准、不确定度评估和验证方法的要求，通过三维（3D）场重建确定感兴趣体积内的psSAR。这些协议和程序适用于包括儿童在内的绝大多数人在使用靠近头部或身体的无线通信设备时的psSAR评估。 本文件适用于距离人体头部或身体不超过200毫米的无线通信设备。本文件可用于评估不同类型无线通信设备的SAR合规性，包括但不限于靠近耳朵、面部前方、安装在身体上、与其他RF发射或非发射设备或配件（如皮带夹）结合使用，或嵌入服装中的设备。总体适用频率范围为600 MHz至6 GHz。 本文件提供的系统验证程序覆盖了600 MHz至6 GHz的频率范围。 使用基于矢量测量的系统，本文件可用于评估不同类型无线通信设备的SAR合规性。 无线通信设备类别包括但不限于移动电话、无线麦克风、辅助广播设备和个人计算机、台式机和笔记本电脑设备中的无线电发射器、多频段、多天线和按下通话设备。 [外文原描述]： IEC 62209-3: 2019 specifies measurement protocols and test procedures for the reproducible measurement of peak spatial-average specific absorption rate (psSAR) induced inside a simplified model of a human head or body by radio-frequency (RF) transmitting devices, with a specified measurement uncertainty. Requirements are provided for psSAR assessment using vector measurement-based systems. Such systems determine the psSAR by three-dimensional (3D) field reconstruction within the volume of interest in accordance with the requirements herein for the measurement system, calibration, uncertainty assessment and validation methods. The protocols and procedures apply for the psSAR assessments covering a significant majority of people including children during use of wireless communication devices operated in close proximity to the head or body. This document is applicable to wireless communication devices intended to be used at a position near the human head or body at distances up to and including 200 mm. This document may be employed to evaluate SAR compliance of different types of wireless communication devices used next to the ear, in front of the face, mounted on the body, combined with other RF-transmitting or non-transmitting devices or accessories (e.g. belt-clip), or embedded in garments. The overall applicable frequency range is from 600 MHz to 6 GHz. The system validation procedures provided within this document cover frequencies from 600 MHz to 6 GHz. With a vector measurement-based system this document can be employed to evaluate SAR compliance of different types of wireless communication devices. The wireless communication device categories covered include but are not limited to mobile telephones, cordless microphones, auxiliary broadcast devices and radio transmitters in personal computers, desktop and laptop devices, multi-band, multi-antenna, and push-to-talk devices. Key Words: Human Exposure, Hand-Held and Body Mounted Wireless Communication Devices.
