人体照射评价用测定无线电通信基站附近的无线电频率场强度和SAR的方法

[中文适用范围]： 本国际标准提供了测定无线电通信基站（RBS）附近射频（RF）场强和比吸收率（SAR）的方法，以评估人体暴露情况。该标准： a) 考虑使用 300 MHz 至 6 GHz 范围内的一个或多个频率在一根或多根天线上传输的 RBS； b) 描述了几种射频场强和 SAR 测量和计算方法，并提供了其适用性的指导，以解决已安装的 RBS 的现场评估和基于实验室的评估； c) 描述具有足够专业水平的验船师应如何建立适合其评估目的的具体评估程序； d) 考虑评估目的@，即： 1) 产品符合性：确定 RBS 在其预期用途下符合一组定义的限制条件； 2) 合规边界：建立与一组定义的限制条件相关的 RBS 合规边界； 3) 评估一个或多个评估地点@的射频场强或 SAR 值，即： i) 控制边界外任意地点的评估地点，为相关方提供信息； ii) 控制边界处的评估位置，以确认控制边界的有效性； iii) 控制范围内的评估地点，具有与调查涉嫌过度暴露事件相关的具体条件； e) 提供关于如何报告@解释和比较不同评估方法的结果以及@在评估目的需要时@根据极限值确定合理决定的指导； f) 提供有关如何评估 RBS 附近来自除被评估 RBS 之外的射频源以及 300 MHz 至 6 GHz 范围内和之外的频率的环境 RF 场强水平的信息指南； g) 提供了信息示例案例研究的简短描述，以帮助在配套技术报告 IEC 62669 [54] 中给出的测量员。 [外文原描述]： IEC 62232:2011 addresses the evaluation of RF field strength or specific absorption rate levels in the vicinity of non-broadcast RF radiocommunication sources (i.e. RBS) intentionally radiating in the frequency range 300 MHz to 6 GHz according to the scope (see Clause 1). It does not address the evaluation of current density which exposure guidelines often do not consider to be relevant when evaluating RF fields in the intended RBS operating frequency range. This standard defines how a suitably qualified surveyor shall select between the described evaluation methods in order to prepare specific or generic evaluation plans and how to validate their implementation. When using this standard to establish RBS compliance, the full set of limiting conditions needs to be defined. These may include for example limits on human exposure to RF fields; the likelihood that people may have access to a specific location; specific decision rules for interpretation of uncertainty. This standard does not define such limits or the associated requirements for a safety programme. Further, this standard recognises that national regulators (or the test client) may establish rules (termed "assessment schemes") on how to interpret uncertainty when establishing compliance. However, this standard does provide guidance on how to apply the described evaluation methods consistent with such rules. Additional guidance can be found in Technical Report IEC 62669 [54]) which includes a set of worked case studies giving practical examples of the application of this standard.
