SAR测试基础标准IEC 62209-1重大更新
为了适应市场的要求,国际IEC的标准也不断的更新中。IEC(International Electrotechnical Commission)于2016年7月发布新版本的SAR (比吸收率) 测试基础标准之一, IEC 62209-1,详情如下:IEC 62209-1:2016 Measurement procedure for the assessment of specific absorption rate of human exposure to radio frequency fields from hand-held and body-mounted wireless communication devices - Part 1: Devices used next to the ear (Frequency range of 300 MHz to 6 GHz)
IEC 62209-1:2016方法针对手持和身体佩戴使用的无线通信设备对人体的电磁照射的测量程序的评估—第1部分:靠近耳边使用的手持式无线通信设备的SAR评估规程(频率范围300 MHz~6 GHz)。
u IEC 62209-1:2016总概
Ü IEC62209-1:2016 specifies protocols and test procedures for measurement of the peak spatial-average SAR induced inside a simplified model of the head with defined reproducibility. It applies to certain electromagnetic field (EMF) transmitting devices that are positioned next to the ear, where the radiating structures of the device are in close proximity to the human head, such as mobile phones, cordless phones ,certain headsets, etc. These protocols and test procedures provide a conservative estimate with limited uncertainty for the peak-spatial SAR that would occur in the head for a significant majority of people during normal use of these devices. The applicable frequency range is from 300 MHz to 6 GHz.
IEC62209-1:2016 规定了在具有确定的再现性的头部的简化模型内测量的峰值空间平均SAR的协议和测试程序。 其适用于定位在耳朵附近的某些电磁场(EMF)传输装置,其中装置的辐射结构靠近人类头部,例如移动电话,无绳电话,某些耳机等。这些协议和测试程序提供保守估计,对于在正常使用这些设备期间对于绝大多数人而言在头部中将发生的峰值空间SAR的有限的不确定性。 适用的频率范围为300 MHz至6 GHz。
Ü This second edition cancels and replaces the first edition published in 2005. This edition constitutes a technical revision.
