Railway applications - Electromagnetic compatibility - Part 3-1: Rolling stock - Train and complete vehicle
This European Standard specifies the emission and immunity requirements for all types of rolling stock. It covers traction stock, hauled stock and trainsets including urban vehicles for use in city streets. This European standard specifies the emission limits of the rolling stock to the outside world. The scope of this part of the standard ends at the interface of the rolling stock with its respective energy inputs and outputs. In the case of locomotives, trainsets, trams etc., this is the current collector (pantograph, shoe gear). In the case of hauled stock, this is the AC or DC auxiliary power connector. However, since the current collector is part of the traction stock, it is not entirely possible to exclude the effects of this interface with the power supply line. The slow moving test has been designed to minimize these effects. There may be additional compatibility requirements within the railway system identified in the EMC plan (e.g. as specified in EN 50238). Basically, all apparatus to be integrated into a vehicle meet the requirements of EN 50121-3-2. In exceptional cases, where apparatus meets another EMC Standard, but full compliance with EN 50121-3-2 is not demonstrated, EMC is ensured by adequate integration measures of the apparatus into the vehicle system and/or by an appropriate EMC analysis and test which justifies deviating from EN 50121-3-2. Electromagnetic interference concerning the railway system as a whole is dealt with in EN 50121-2. These specific provisions are to be used in conjunction with the general provisions in EN 50121-1. The frequency range considered is from 0 Hz (DC) to 400 GHz. No measurements need to be performed at frequencies where no requirement is specified.

55 Introduction
56 High power electronic equipment, together with low power microcontrollers and other electronic
57 devices, are being installed on trains in great numbers. Electromagnetic compatibility has therefore
58 become a critical issue for the design of train-related apparatus as well as of the train as a whole.
59 This document for rolling stock sets limits for electromagnetic emission and immunity in order to
60 ensure a well functioning system within its intended environment.
61 Immunity limits are not given for the complete vehicle. EN 50121-3-2 defines requirements for the
62 apparatus installed in the rolling stock, since it is impractical to test the complete unit. An EMC plan
63 includes equipment covered by this document.

64 1 Scope
65 This document specifies the emission and immunity requirements for all types of rolling stock. It covers
66 traction stock, hauled stock and trainsets including urban vehicles for use in city streets. This
67 document specifies the emission limits of the rolling stock to the outside world.
68 The scope of this part of the standard ends at the interface of the rolling stock with its respective
69 energy inputs and outputs. In the case of locomotives, trainsets, trams etc., this is the current collector
70 (pantograph, shoe gear). In the case of hauled stock, this is the AC or DC auxiliary power connector.
71 However, since the current collector is part of the traction stock, it is not entirely possible to exclude the
72 effects of this interface with the power supply line. The slow moving test has been designed to
73 minimize these effects.
74 There may be additional compatibility requirements within the railway system identified in the EMC plan
75 (e.g. as specified in EN 50238).
76 Electromagnetic interference concerning the railway system as a whole is dealt with in EN 50121-2.
77 These specific provisions are to be used in conjunction with the general provisions in EN 50121-1.

115 4 Applicability
116 Generally, it is not possible to test electromagnetic compatibility invoking every function of the rolling
117 stock. The tests shall be made at typical operating modes considered to produce the largest emission.
118 The typical operating mode shall require all systems to be energised which are normally in continuous
119 operation during service. It is not necessary during the test to exercise systems which operate
120 transiently such as for example operation of internal doors, although they should be energised. It is not
