- compatibility assessment relating to harmonics and dynamic effects.
Informative values are given for some parts of the existing European railway networks, in annexes.
NOTE For those railways within the scope of EU Interoperability Directive, definitive values are set out in the register of infrastructure published in accordance with Article 49 of Directive (EU) 2016/797, and the list of items included in the register is described in the commission decision (EU) 2019/777.
The following electric traction systems are within the scope of this document:
- railways;
- guided mass transport systems that are integrated with railways;
- material transport systems that are integrated with railways.
Information is given on electrification parameters to enable train operating companies to confirm, after consultation with the rolling stock manufacturers, that risks of non-compatibility are minimized and that there will be no consequential disturbance on the electrification system.
The interaction between pantograph and overhead contact line is dealt with in EN 50367:2020.
The interaction with the control-command and signalling subsystem is not dealt with in this document.
Basic considerations have been included concerning the use of traction units with onboard electric traction energy storage in the electric traction power system. Details of this are dealt with in CLC/TS 50729:2025.

Equipment for general lighting purposes - EMC immunity requirements
Scope: This part of IEC 61547 which deals with electromagnetic immunity requirements, applies to lighting equipment which is within the scope of IEC technical committee 34, including apparatus such as lamps, luminaires, controlgear for electric light sources, and end-user replaceable modules like non-integrated and semi-integrated LED lamps and LED modules.
Lighting equipment with a wireless control function are also within the scope of this document. However, the test is limited to the control of the lighting function only. Radio properties like frequency stability or spurious emissions are not assessed.
EXAMPLE Colour/light level control via a wireless interface are meant to stay intact during and after an immunity test.
Also included in the scope of this document is lighting equipment that interfaces with systems or installations other than common power supply networks.
Excluded from the scope of this document are:
– components or modules designed to be integrated into lighting equipment but not intended for end-user replacement.
– equipment for which the electromagnetic compatibility requirements in the radio-frequency range are explicitly formulated in other product immunity standards, even if they incorporate a built-in lighting function.
NOTE 1 Examples of exclusions are: – equipment with built-in lighting devices for display back lighting, scale illumination and signaling;
– SSL-displays;
– range hoods, refrigerators, freezers; – photocopiers, projectors;
– electronic switches for fixed installations;
– lighting equipment for road vehicles (within the scope of CISPR 12);
– lighting equipment for aircraft and airfield facilities.
NOTE 2 Modules that are not end-user replaceable are not in the scope of this document but can be tested according to this document for information purposes (for instance, of luminaire manufacturers).
In multi-function equipment where the lighting function operates independently from other functions, the electromagnetic immunity requirements of this document apply to the lighting function only.
The requirements of this document are based on the generic immunity standard for residential, commercial and light-industrial environments IEC 61000-6-1:2016, but modified to lighting engineering practice.
It can be expected that lighting equipment complying with the requirements of this document will operate satisfactorily in other environments. In some special cases, measures can be taken to provide higher immunity. In this document it is impracticable to deal with all these possibilities.
Such requirements can be established by contractual agreement between supplier and purchaser.
This document does not cover the effects that electromagnetic disturbances have on the lifetime of lighting equipment.
