Summary: This International Standard specifies the measurement and simulation/calculation methods for the strength of the magnetic field in a rail transit environment in the presence of a human being (including a population of pacemakers) but does not take into account the effects of high power transients, Ground fault and transformer overshoot, etc.); passenger and personal electronic equipment (such as mobile phones, notebook computers and wireless communication systems); and special transmitters with frequencies above 20 kHz. This standard is applicable to equipment, systems and ground installations in the rail transit environment with a magnetic field of 0 GHz to 300 GHz. Due to the natural nature of the magnetic field source in the rail transit environment, only the values ??of the magnetic field from 0 kHz to 20 kHz are considered and measured.

Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009. This standard uses the re-drafting method to modify the use of IEC /T S62597..2011 "Rail traffic in the environment of electronic and electrical equipment Of the magnetic field strength measurement method ". There are technical differences between this standard and IEC /T S62597..2011, and the terms involved in these differences have passed through the White vertical line (︱) were marked, the main technical differences and the reasons are as follows. --- on the normative reference documents, this standard has made a technical differences in the adjustment to meet China's technical conditions, adjust the situation The situation is reflected in Chapter 2, "Normative references", as follows. • Replace IEC 62236 (all parts) with GB/T 24338 (all parts) (see Chapter 3); between the two standard parts The degree of consistency is as follows. Railways - Electromagnetic compatibility - Part 1. General principles (IEC 62236-1..2003, IDT); GB/T 24338.2-2011 Electromagnetic compatibility for rail transit Part 2. Launch of the entire track system to the outside world (IEC 62236-2..2003, IDT); Railways - Electromagnetic compatibility - Part 3-1. Locomotives and rolling stock - Trains and vehicles - GB/T 24338.3-2009. (IEC 62236-3-1..2003, IDT); Railways - Electromagnetic compatibility - Part 3-2.

1 Scope

This standard specifies the measurement of the magnetic field strength in the orbital traffic environment where the human body (including the population with the pacemaker) And simulation/calculation methods, but did not consider the following factors. --- high power transients (such as short circuit, ground fault and transformer overshoot, etc.); - personal and personal computer equipment (such as mobile phones, laptops and wireless communication systems, etc.); --- Dedicated transmitter with frequency higher than 20kHz. This standard applies to the magnetic field frequency of 0GHz ~ 300GHz rail transit environment in the equipment, systems and ground devices. Due to the natural characteristics of the magnetic field source in the rail transit environment, only the values of the magnetic field of 0 kHz to 20 kHz are considered and measured.
