DANSK DS/IEC 62597 PDF

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< ...
