有源植入式医疗器械辐射抗扰度试验辐射强度研究

Research on Field Strength of Radiated Immunity Test for Active Implantable Medical Devices

摘要: 为了比较ISO 14708系列标准中辐射抗扰度试验等级和国内外关于环境辐射标准的限值的场强大小关系，并进而确定辐射抗扰度试验测试的强度是否达到了相关辐射环境标准所要求的辐射强度的限值水平，该文通过建模计算了ISO 14708标准中辐射抗扰度试验对样品产生的场强和辐射功率密度，并和ICNIRP 1998及GB 8702—2014的限值进行了比较。

Abstract: In order to compare the radiation immunity test level of ISO 14708 series standards and the domestic and international environmental radiation standards and then to ascertain whether the radiated immunity test level has reached the limit of the radiation strength in the relevant radiation environmental standards, this paper calculated the radiation field intensity and power density according to the radiated immunity test of ISO 14708 standards, and compared with the limit of ICNIRP 1998 and GB 8702-2014.
