This product standard applies to fixed stand alone broadcast transmitter operating in the frequency range 30 MHz to 40 GHz when put on the market. The term broadcast transmitter covers fixed stand alone broadcast transmitters intended for use with external antennas of the same or an other manufacturer. The object of this standard is to demonstrate the compliance of such equipment with the reference levels or the basic restrictions related to public exposure to radio frequency electromagnetic fields.

Produktnorm zum Nachweis der Übereinstimmung von einzelnen Rundfunksendern mit den Referenzwerten oder den Basisgrenzwerten bezüglich der Exposition der Allgemeinbevölkerung gegenüber hochfrequenten elektromagnetischen Feldern (30 MHz bis 40 GHz)

Diese Norm gilt für einzelne ortsfeste (stationäre) Rundfunksender, die im Frequenzbereich 30 MHz bis 40 GHz betrieben werden, wenn sie in Verkehr gebracht werden. Der Begriff Rundfunksender umfasst einzelne ortsfeste (stationäre) Rundfunksender, die zur Verwendung mit externen Antennen des gleichen oder eines anderen Herstellers vorgesehen sind. Zweck dieser Norm ist, für diese Einrichtungen und Anlagen die Übereinstimmung mit den in Bezug auf die Sicherheit von Personen in hochfrequenten elektromagnetischen Feldern in öffentlichen Bereichen festgelegten Referenzwerten oder Basisgrenzwerten nachzuweisen.

Norme produit pour démontrer la conformité des émetteurs de radiodiffusion isolés par rapport aux niveaux de référence ou aux restrictions de base relatifs à l'exposition du public aux champs électromagnétiques (30 MHz - 40 GHz)

Cette norme s’applique aux émetteurs de radiodiffusion isolés fonctionnant dans la gamme de fréquence de 30 MHz à 40 GHz, lors de leur mise sur le marché. Le terme d’émetteur de radiodiffusion couvre les émetteurs de radiodiffusion isolés et fixes, destinés à être utilisés avec des antennes extérieures provenant ou non du même fabricant. L’objet de cette norme est de démontrer la conformité de tels équipements avec les niveaux de référence ou les restrictions de base relatifs à l’exposition du corps humain aux champs électromagnétiques radiofréquences.

1 Scope

This product standard applies to fixed stand alone broadcast transmitter operating in the frequency range

30 MHz to 40 GHz when put on the market. The term broadcast transmitter covers fixed stand alone

broadcast transmitters intended for use with external antennas of the same or an other manufacturer.

The object of this standard is to demonstrate the compliance of such equipment with the reference levels

or the basic restrictions related to public exposure to radio frequency electromagnetic fields.

2 Normative references

The following referenced documents are indispensable for the application of this document. For dated

references, only the edition cited applies. For undated references, the latest edition of the referenced

document (including any amendments) applies.

EN 50420, Basic standard for the calculation and measurement of human exposure to electromagnetic

fields from stand alone broadcast transmitters (30 MHz – 40 GHz)

Council Recommendation 1999/519/EC of 12 July 1999 on the limitation of exposure of the general public

to electromagnetic fields (0 Hz to 300 GHz) (Official Journal L 199 of 30 July 1999)

3 Physical quantities, units and constants
Physical quantities, units and constants are defined in EN 50420.
4 Definitions
For the purposes of this document, the following terms and definitions apply.
4.1
basic restriction

restrictions on exposure to time-varying electric, magnetic, and electromagnetic fields that are based

directly on established health effects. In the frequency range from 30 MHz to 10 GHz, the physical

quantity used is the specific absorption rate. Between 10 GHz and 40 GHz, the physical quantity is the

power density
4.2
broadcasting service

radiocommunication service in which the transmissions are intended for direct reception by the general

public. This service may include sound transmissions, television transmissions or other types of

transmission
4.3
compliance distance

minimum distance from the antenna where a point of investigation is deemed to be compliant. The set of

compliance distances therefore defines the boundary outside which the exposure levels do not exceed

the basic restrictions irrespective of
