SIST EN 50500:2008

Measurement procedures of magnetic field levels generated by electronic and electrical apparatus in the railway environment with respect to human exposure

The scope of this product-family standard 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 necessary 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 standard 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 being during exposure to non-ionizing electromagnetic fields in the railway environment are different within the countries of European Community. This standard offers a procedure regarding measurement, simulation and evaluation. At present two European documents regarding EMF have to be considered: a)   Council Recommendation 1999/519/EC of 12 July 1999 (see Bibliography); b)   Directive 2004/40/EC (see Bibliography). The measurement procedures and points of measurement cover also the aspect of persons bearing active implantable medical devices. NOTE 1   Not covered is the risk assessment for persons bearing active implants in magnetic field generated by electronic and electrical apparatus in the railway environment. Not covered are personal electronic devices (e.g. mobile phones, notebooks, wireless communication systems etc.) of passengers and workers. Not covered are intentional transmitters with frequencies higher than 20 kHz. NOTE 2   These apparatus (with a working frequency of 9 kHz or higher) are covered by R&TTE Directive and have to comply also with LVD (Low Voltage Directive). In this view these apparatus have also limitation of EM fields or a “safety-distance” for these apparatus must be given.

Messverfahren für magnetische Felder, die durch elektronische und elektrische Geräte in der Bahnumgebung erzeugt werden, hinsichtlich der Exposition von Personen

Der Anwendungsbereich dieser Produktfamilien Norm ist begrenzt auf Geräte, Systeme und ortsfeste Anlagen, die im Eisenbahnbereich eingesetzt werden. Der abgedeckte Frequenzbereich beträgt 0 Hz bis 300 GHz. Technische Betrachtungen und Messungen sind in einem Frequenzbereich bis zu 20 kHz erforderlich, da oberhalb bedingt durch die physikalischen Eigenschaften der EMF-Quellen keine relevanten Feldstärken im Bahnbereich erwartet werden. Das Ziel dieser Norm ist die Festlegung geeigneter Mess- und Berechnungsverfahren von elektrischen und magnetischen Feldern, die durch elektronische und elektrische Geräte in der Bahnumgebung erzeugt werden, hinsichtlich der menschlichen Exposition. Die Bestimmungen bezüglich des Personenschutzes während der Exposition in nicht ionisierenden elektromagnetischen Feldern in der Bahnumgebung sind unterschiedlich in den Ländern der Europäischen Gemeinschaft. Diese Norm bietet ein Vorgehen bezüglich Messung, Simulation und Berechnung an. Derzeit sind zwei Europäische Dokumente bezüglich EMF in Betracht zu ziehen: a)   Ratsempfehlung 1999/519/EG vom 12. Juli 1999 (siehe Literaturhinweise); b)   Richtlinie 2004/40/EG (siehe Literaturhinweise). Die Messverfahren und Messorte decken auch den Aspekt von Trägern aktiver implantierbarer medizinischer Geräte mit ab. ANMERKUNG 1   Die Risikobewertung für Träger aktiver implantierbarer medizinischer Geräte in Magnetfeldern, die durch elektronische und elektrische Geräte in der Bahnumgebung erzeugt werden, wird nicht betrachtet. Nicht betrachtet werden persönliche elektronische Geräte (z. B. Funktelefone, Notebooks, drahtlose Kommunikationssysteme etc.) von Fahrgästen und Arbeitnehmern. Nicht betrachtet werden Sendefunkgeräte mit Arbeitsfrequenzen über 20 kHz. ANMERKUNG 2   Diese Sendefunkgeräte (mit einer Arbeitsfrequenz von 9 kHz oder höher) sind im Anwendungsbereich der R&TTE Richtlinie und müssen ebenfalls die NSR (Niederspannungsrichtlinie) einhalten. Diesbezüglich haben diese Geräte eine Begrenzung der erlaubten EMFelder oder es muss für diese Geräte ein „Sicher-heitsabstand“ angegeben werden.

Procédures de mesure des niveaux de champ magnétique générés par les appareils électriques et électroniques dans l'environnement ferroviaire en regard de l'exposition humaine

Le domaine d’application de cette norme de famille de produits est limité aux appareils, systèmes et installations fixes destinés à être utilisés dans l’environnement ferroviaire. La gamme de fréquences couverte est comprise entre de 0 Hz et 300 GHz.  Des considérations techniques et des mesures sont nécessaires pour des fréquences jusqu’à 20 kHz parce qu’aucune intensité de champ correspondante n’est prévue au-dessus de cette fréquence, en raison de la nature physique des sources d’EMF dans l’environnement ferroviaire. L’objet de cette norme est de fournir des procédures de mesure et de calcul des niveaux de champ magnétique et électrique générés par des appareils électroniques et électriques dans l’environnement ferroviaire en regard de l’exposition humaine. La réglementation relative à la protection des êtres humains au cours d’une exposition aux champs électromagnétiques non-ionisants dans l’environnement ferroviaire est différente au sein de la Communauté Européenne en fonction des pays. Cette norme propose une procédure relative à la mesure, la simulation et l’évaluation. Actuellement deux documents européens relatifs aux champs électromagnétiques (EMF) doivent être pris en compte: a)   Recommandation du Conseil 1999/519/CE du 12 juillet 1999 (voir la Bibliographie); b)   Directive 2004/40/CE (voir la Bibliographie). Les procédures et points de mesure couvrent également l’aspect relatif aux personnes équipées de dispositifs médicaux implantables actifs. NOTE 1 L'évaluation du risque pour les personnes équipées de dispositifs médicaux implantables actifs, dans un champ magnétique généré par de l'appareillage électrique et électronique dans l'environnement ferroviaire n'est pas couverte. Les dispositifs électroniques personnels des passagers et des travailleurs (par exemple, les téléphones mobiles, les ordinateurs portables, les systèmes de communication sans fil etc.) ne sont pas couverts. Les émetteurs intentionnels de fréquences supérieures à 20 kHz ne sont pas couverts. NOTE 2   Ces appareils (avec une fréquence de fonctionnement de 9 kHz ou supérieure) sont couverts par la directive R&TTE et doivent également être conformes à la DBT (Directive Basse Tension). C’est pourquoi soit ces appareils ont aussi une limite de champ électromagnétique, soit une “distance de sécurité” doit être donnée pour ces appareils.

Overview

EN 50500:2008 - Measurement procedures of magnetic field levels generated by electronic and electrical apparatus in the railway environment with respect to human exposure - is a CLC (CENELEC) product‑family standard that defines how to measure, simulate and evaluate magnetic fields produced by railway equipment. The standard covers apparatus, systems and fixed installations intended for use in the railway environment over the broad frequency range 0 Hz to 300 GHz, with practical measurement and technical focus up to 20 kHz (magnetic fields dominate in this range). EN 50500:2008 provides standardized procedures to demonstrate compliance with human‑exposure limits referenced in European documents such as Council Recommendation 1999/519/EC and Directive 2004/40/EC.

Key topics and requirements

• Scope and limits: Applies to rolling stock, traction power systems and fixed infrastructure in the railway environment; excludes personal electronic devices and intentional transmitters above 20 kHz.
• Frequency focus: Measurements and calculations are primarily for d.c. to 20 kHz (magnetic field effects); generic scope stated 0 Hz–300 GHz.
• Measurement points and heights:
  • Inside rolling stock: public areas (0.3 m, 0.9 m, 1.5 m above floor); worker areas (0.9 m, 1.5 m); close to emission sources and driver seat.
  • Outside rolling stock: 0.3 m horizontal distance from train enclosure; heights 0.5 m, 1.5 m, 2.5 m above top of running rails.
  • Open route distances (public): main line 10 m, urban transport 3 m (unless local regulation applies); trams/trolleybuses 0 m.
• Test regimes: Two cases - (1) rolling stock (measurements inside/outside trains) and (2) fixed installations/infrastructure (measurements and simulation of worst‑case scenarios).
• Simulation & validation: Use simulation/calculation to estimate worst‑case fields when measurements cannot cover them; validate models against measurements; harmonics <10% of limit may be neglected.
• Special considerations: Measurement procedures consider persons with active implantable medical devices (AIMDs), though full risk assessment for implants is not covered.
• Reporting & test plan: Standard prescribes test plans, measurement execution, equipment and evaluation methods.

Applications and users

EN 50500:2008 is used by:

• Railway manufacturers and rolling‑stock designers to assess on‑board EMF exposure.
• Infrastructure managers for substations, overhead lines and platform safety assessments.
• EMC and safety engineers conducting magnetic field testing, simulation and compliance verification.
• Accredited test laboratories applying EN ISO/IEC 17025 practices for measurement and reporting.
• Regulatory and safety officers demonstrating conformity with EU exposure recommendations and directives.

Practical outputs include measurement reports, validated simulation models, safety distances and compliance evidence for workers and public exposure in railway environments.

Introduction
The intention of this European Standard is to establish a suitable measuring/calculation
method for determining the magnetic fields in the space around the equipment mentioned in
the scope, to standardize operating conditions and to fix measuring/calculation distances. It
offers a method to demonstrate compliance with the council recommendation 1999/519/EC
(see Bibliography) and Directive 2004/40/EC (see Bibliography).

1 Scope
The scope of this product-family standard 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 necessary 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 standard 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 being during exposure to non-ionizing
electromagnetic fields in the railway environment are different within the countries of
European Community. This standard offers a procedure regarding measurement, simulation
and evaluation.
At present two European documents regarding EMF have to be considered:
a) Council Recommendation 1999/519/EC of 12 July 1999 (see Bibliography);
b) Directive 2004/40/EC (see Bibliography).

The measurement procedures and points of measurement cover also the aspect of persons
bearing active implantable medical devices.

NOTE 1  Not covered is the risk assessment for persons bearing active implants in magnetic field generated by
electronic and electrical apparatus in the railway environment.

Not covered are personal electronic devices (e.g. mobile phones, notebooks, wireless
communication systems etc.) of passengers and workers.

Not covered are intentional transmitters with frequencies higher than 20 kHz.

NOTE 2  These apparatus (with a working frequency of 9 kHz or higher) are covered by R&TTE Directive and
have to comply also with LVD (Low Voltage Directive). In this view these apparatus have also limitation of EM
fields or a “safety-distance” for these apparatus must be given.

4 Measurement procedure
4.1 General
In railways three electromagnetic sources can affect human beings: rolling stock, traction
power supply and signalling equipment.

According to generic EMF standard EN 50392, there are two separate summation regimes
for simultaneous exposure to fields of different frequencies. They depend of the effects of the
exposure. In the frequency range from 1 Hz to 10 MHz the electrical stimulation is relevant
and the underlying basic restriction is induced current density. In the frequency range from
100 kHz to 300 GHz, thermal effects are relevant.

As the detectable emission of rolling stock, traction power supply and signalling equipment is
in the frequency range from d.c. up to 20 kHz, measurements, simulation and calculation are
restricted to this range. Accordingly only one summation regime is applied. In this frequency
range the magnetic field is dominant and the electric field can be neglected.

As power of signalling equipment is low in comparison with other sources of EMF in the
railway environment, its contribution can be neglected.

The measurement procedure of the whole railway system is divided into two cases.

Case 1: Rolling stock (see 4.2)
- measurements inside rolling stock and
- measurements outside rolling stock (on platform or alternative)

Case 2: Fixed installation of existing infrastructure (see 4.3)
- measurement of existing railway infrastructure
- simulation/calculation of worst case situation (e.g. bridges, level crossing, max. possible
current in overhead lines, third rails)

NOTE 1 Compliance of rolling stock can be demonstrated with the first explained case. Compliance of
infrastructure can be demonstrated with the second explained case.

For the apparatus, systems and fixed installations in railway environment there are basic
restrictions for general public and workers specified in 1999/519/EC, 2004/40/EC, ICNIRP
Guidelines to static magnetic fields, ICNIRP guidelines to time-varying electric, magnetic and
electromagnetic fields (see Bibliography).

- 7 - EN 50500:2008
With compliance of both cases, it can be assumed that the whole railway system is in
compliance with the basic restrictions referenced in this standard.

For active medical implantable devices there is only a susceptibility limit to d.c. magnetic
fields given in EN 45502-2-1.
NOTE 2 The process defined in this chapter applies also to demonstrate the compliance of railway equipment
with active implantable medical devices.

Subclause 4.2 defines the measurement points in established areas inside and outside
rolling stock.
Subclause 4.3 defines the measurement points in established areas in fixed installation and
gives details regarding simulation/calculation.

Subclause 4.4 defines the test conditions during the measurement of the magnetic field.

Subclause 4.5 is related to the test environment.

A test plan for rolling stock and infrastructure is given in Annex A.

4.2 Rolling stock
The following measurement points are specified inside and outside rolling stock:

4.2.1 Accessible areas for workers inside rolling stock

The measurements indicate the emissions of the train equipment in standstill and dynamic
condition (see 4.4.1).
Measurements shall be carried out close to the sources of emission of the train (e.g. power
converters, power cables and power inductors) where workers usually can be in normal
operating conditions of train and appliance and at the driver seat. The measurement heights
above the floor shall be 0,9 m and 1,5 m. The horizontal measuring distance to the walls is
0,3 m or at the minimum distance (> 0,3 m) where workers can be.

Working areas are described in the scope of 2004/40/EC (see Bibliography).

4.2.2 Public areas inside rolling stock

The measurements indicate the emissions of the train equipment in standstill and dynamic
condition (see 4.4.1).
Measurements shall be carried out at the closest possible position of the sources of emission
of the train (e.g. power converters, power cables and power inductors), where public can be.
In this case then the measurement heights above the floor of all the public areas shall be
0,3 m, 0,9 m and 1,5 m. The horizontal measuring distance to the walls is 0,3 m or at the
minimum distance (> 0,3 m) where public can be.

4.2.3 Areas outside rolling stock (public and workers)

The measurements close to rolling stock indicate the emissions of the train equipment in
standstill condition (see 4.4.1) in 0,3 m horizontal distance to the train enclosure at the
closest possible position of the sources of emission of the train (e.g. power converters, power
cables and power inductors) at 0,5 m, 1,5 m and 2,5 m height from the top of the running
rails.
Measurements for public shall not be carried out at the same side of the third rail with respect
to the tracks.
4.3 Fixed installation
Demonstration of compliance of the existing infrastructure shall include fixed electric traction
system of railway environment.

Positions where compliance has to be demonstrated are given in 4.3.1 to 4.3.3.

Simulation/calculation can give worst case figures (see 4.3.4).

A test plan is given in Annex A.

4.3.1 Open railway route (public and worker)

Measurements and/or simulation/calculation regarding public shall be carried out in the
distances from the centre of the nearest track of regarded system as given below or in higher
distances within the nearest accessible area for public, 1,5 m above ground level (standing
area) where people can be at the detected location.

Table 1 – Location and distances
Location Horizontal distance from Remark
centre of track
Main line 10 m (for public) If not regulated by
legislative requirements
Urban transport 3 m (for public) If not regulated by
legislative requirements
Trams, trolley buses, etc. 0 m
Level crossings 0 m
Bridges 0 m
Underpass 0 m
NOTE 1 Combined systems (main line and urban line close together) have to be regarded individually which
may lead to other distances.
NOTE 2 There may be cases where the location of maximum field strength is different from the centre of the
track. In these cases the place with the maximum field strength has to be considered.

Measurements for workers on open railway routes shall be carried out at the closest possible
(not restricted) position to the sources of emission where workers can be.

Short circuit conditions are excluded.

- 9 - EN 50500:2008
4.3.2 Areas close to fixed power supply installations (public and workers)

Measurements and/or simulation/calculation shall be carried out at the closest possible (not
restricted) position to the sources of emission from substation where public and workers can
be (e.g. as marked on the floor or given by fences). In this case then the consideration of all
the public areas shall be at heights of 0,3 m, 0,9 m and 1,5 m and of all the worker areas
shall be at heights of 0,9 m and 1,5 m. The horizontal measuring distance to the walls or
fences is 0,3 m or at the minimum distance (> 0,3 m) where public and workers can be.

4.3.3 Platform (public and worker)

Measurements and/or simulation/calculation on the platform shall be carried out at heights of
0,9 m and 1,5 m above the platform level and with 0,3 m horizontal distance from the edge of
the platform.
4.3.4 Simulation/calculation
If measurements cannot cover the worst case conditions, simulation/calculation with
maximum expected current values (to be set by the infrastructure manager) shall be carried
out. Harmonics known to be lower than a threshold value of 10 % of the limit value can be
neglected.
Validation of the calculation/simulation shall be performed by comparison between
calculated/simulated results and measured values for known conditions.

4.4 Test conditions
4.4.1 Test of rolling stock
Tests are to be done under normal operating conditions, only.

The condition of the rolling stock during the magnetic field measurements is described below:

- Stand still condition (S)
The rolling stock is not moving.
The traction circuits shall be under voltage but not operating. The auxiliary circuits shall
operate and all the relevant appliances shall be active (e.g. air conditioning/heating,
lights, window heater, electric generators).

- Dynamic condition (D)
The rolling stock starts from the standstill with maximum
...
