BS EN 50400:2006 pdf download.Basic standard to demonstrate the compliance of fixed equipment for radio transmission (110 MHz-40 GHz) intended for use in wireless telecommunication networks with the basicrestrictions or the reference levels related togeneral public exposure toradio frequency electromagnetic fields,when put into service.
This principle is applied in three ways:
• to define the area outside which the contribution to the total exposure ratio from the Equipment Under Test in service need not be considered either for its compliance or its possible effect on other sources compliance;
• to establish if the exposure ratio from each individual radio source is relevant and needs to be considered as a contributor to the total exposure ratio;
• to establish whether RF fields from the Equipment Under Test, when reflected by nearby structures, may increase by a significant amount the exposure ratio within the compliance boundary of the Equipment Under Test.
6.2 DetermInation of domains
6.2.1 Relevant domain
6.2.1.1 General procedure
The relevant domain shall be determined using the calculation or measurement methods described in Clauses 7 and 8. At the relevant domain boundary, the exposure ratio from the Equipment Under Test shall be less than or equal to 0,05.
6.2.1.2 Simplified procedure
If the compliance boundary has been determined with respect to reference levels and according to EN 50383, the relevant domain boundary can be derived by multiplying the smallest distance between the radiating part of the antenna and the compliance boundary by a factor of 5 in a given direction (Annex C).
6.2.2 Scatter domain
6.2.2.1 General procedure
The scatter domain shall be determined using the calculation or measurement methods described in Clauses 7 and 8 or in EN 50383. At the scatter domain boundary, the Equipment Under Test exposure ratio shall be less than or equal to 0,1 (Annex C).
6.2.2.2 Simplified procedure
If the compliance boundary has been determined with respect to reference levels and according to EN 50383, the scatter domain boundary can be derived by multiplying the smallest distance between the radiating part of the antenna and the compliance boundary by a factor of 3 in a given direction (Annex C).
