铁路环境中电子和电气设备产生的与人体暴露有关的磁场水平.测量程序

[中文适用范围]： 本文件的范围限于用于铁路环境的设备、系统和固定设施。涵盖的频率范围为0 Hz至300 GHz。由于铁路环境中电磁场源的物理性质，预计高于20 kHz的场强不相关，因此针对该频率的技术考量和测量指定到20 kHz。本文件的目的是提供关于铁路环境中电子和电气设备产生的针对人体暴露的电场和磁场水平的测量和计算程序。世界各国的铁路环境中关于人体暴露于非电离电磁场的保护法规各不相同。本文件提供了关于测量、仿真/计算和评估的程序。测量程序和测量点还涵盖了佩戴有有源植入式医疗器械的人员方面。本文件不适用于铁路环境中电子和电气设备产生的磁场中对佩戴有源植入式医疗器械人员进行风险评估。本文件不适用于乘客和工人的个人电子设备（如移动电话、笔记本电脑、无线通信系统等）。本文件不适用于频率高于20 kHz的有意发射器。 [外文原描述]： IEC 62597:2019 is limited to apparatus, systems and fixed installations which are intended for use in the railway environment. The frequency range covered is 0 Hz to 300 GHz. Technical considerations and measurements are specified for frequencies up to 20 kHz because no relevant field strengths are expected above due to the physical nature of EMF‑sources in the railway environment. The object of this document is to provide measurement and calculation procedures of electric and magnetic field levels generated by electronic and electrical apparatus in the railway environment with respect to human exposure. The regulations regarding the protection of human beings during exposure to non-ionizing electromagnetic fields in the railway environment are different within the countries worldwide. This document offers a procedure regarding measurement, simulation/calculation and evaluation. The measurement procedures and points of measurement cover also the aspect of persons bearing active implantable medical devices. This document does not apply to the risk assessment for persons bearing active implants in magnetic field generated by electronic and electrical apparatus in the railway environment. This first edition cancels and replaces IEC TS 62597 published in 2011. This edition includes the following significant technical changes with respect to the Technical Specification: a) Clause 3.1: The extent of “Terms and definitions” has been updated b) Clause 3 was expanded by clause 3.2 “abbreviated terms” c) Clause 4.2: The “surface method” for Rolling Stock measuement was deleted. Mandatory measurement method is former “volume method” with slightly modified measurement heghts. d) Clause 4.3: Japanese set of measurement heghts for fixed installations was deleted. e) Clause 5.2 and new Annex B: Measurement technique for lower frequency range up to 5 Hz. f) New Annex C: Consistency to IEC 62110 in some countries g) Several editorial improvements have been included in the entire document
