Produktnorm zum Nachweis der Übereinstimmung von Rundfunksendern mit den Referenzwerten und den Basisgrenzwerten bezüglich der Exposition der Allgemeinbevölkerung gegenüber hochfrequenten elektromagnetischen Feldern (3 MHz bis 30 MHz)

Diese Europäische Norm gilt für Kurzwellen-Rundfunksender und -anlagen, die im Frequenzbereich 3 MHz bis 30 MHz betrieben werden. Zweck dieser Norm ist, für diese Einrichtungen die Übereinstimmung mit den in Bezug auf die Sicherheit von Personen in hochfrequenten elektromagnetischen Feldern in öffentlichen Bereichen festgelegten Basisgrenzwerten (direkt oder indirekt durch die Einhaltung von Referenzwerten) nachzuweisen.

Norme produit pour démontrer la conformité des émetteurs de service de radiodiffusion, aux niveaux de référence et aux restrictions de base pour l'exposition du public, dans les bandes HF (3 MHz à 30 MHz)

Cette norme s’applique aux émetteurs d’ondes courtes de radiodiffusion fonctionnant dans la gamme de fréquence de 3 MHz à 30 MHz. L’objet de la présente norme est de démontrer la conformité de tels équipements aux restrictions de base (directement ou indirectement via la conformité aux niveaux de référence) liées à l'exposition du public aux champs électromagnétiques de radiofréquence.

1 Scope

This standard applies to short wave broadcast transmitters operating in the frequency range 3 MHz to

30 MHz.

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

restrictions (directly or indirectly via compliance with reference levels) related to public human

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 50475 , Basic standard for the calculation and the measurement of human exposure to

electromagnetic fields from broadcasting service transmitters in the HF bands (3 MHz - 30 MHz)

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
antenna

device that serves as a transducer between a guided wave (e.g. coaxial cable) and a free space wave,

or vice versa
3.2
basic restriction

restrictions of 1999/519/EC [1] on exposure to time-varying electric, magnetic, and electromagnetic

fields that are based directly on established health effects
3.3
broadcasting service

radio communication 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
3.4
compliance distance

minimum distance from the antenna to a point of investigation where field level is deemed to be

compliant to the limits
3.5
compliance boundary

surface around the antenna outside of which all field levels are deemed to be compliant to the limits

3.6
contact current (IC)

contact current between a person and an object exposed to the field, is expressed in amperes (A).

A conductive object in an electric field can be charged by the field
