标准范围

IEC 62597:2019仅限于用于铁路环境的设备、系统和固定装置。覆盖的频率范围为0 Hz至300 GHz。对于高达20 kHz的频率，规定了技术考虑和测量，因为由于EMF的物理特性，预计不会有相关的场强？铁路环境中的来源。本文件的目的是提供铁路环境中由电子和电气设备产生的关于人类暴露的电场和磁场水平的测量和计算程序。世界各国关于在铁路环境中暴露于非电离电磁场期间保护人类的法规各不相同。本文件提供了关于测量、模拟/计算和评估的程序。测量程序和测量点还涵盖携带有源植入式医疗装置的人的方面。本文件不适用于铁路环境中电子电气设备产生的磁场中携带有源植入物的人员的风险评估。第一版取消并取代了2011年发布的IEC TS 62597。此版本包括与技术规范相关的以下重大技术变更:a)第3.1条:更新了“术语和定义”的范围b)第3条由第3.2条“缩略术语”扩展c)第4.2条:删除了机车车辆测量的“表面法”。强制测量方法是以前的“体积法”，测量高度略有修改。d)第4.3条:删除了固定装置的日本测量高度集。e)第5.2条和新附件B:5 Hz以下低频范围的测量技术。f)新附件C:在某些国家与IEC 62110的一致性g)整份文件在编辑上作了一些改进

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
