BS EN 50385:2017EN 50385:2017 (E) 4 1 Scope This product standard is related to human exposure to radiofrequency electromagnetic

27、fields transmitted by base station equipment in the frequency range 110 MHz to 100 GHz. The object is to assess the compliance of such equipment with the general public basic restrictions (directly or indirectly via compliance with reference levels) and the workers exposure limit values (directly or

28、 indirectly via compliance with action levels), when it is placed on the market. For low power devices the applicable product standard is EN 50663:2017. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its appl

29、ication. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

33、 Respect of the action level will ensure respect of the relevant exposure limit value. If the action level is exceeded, it does not necessarily follow that the exposure limit value will be exceeded. 3.2 basic restrictions restrictions on exposure of the general public to electric, magnetic, and elec

34、tromagnetic fields that are based directly on established health effects and biological considerations 3.3 base station BS fixed equipment including the radio transmitter and associated antenna(s) as used in wireless telecommunications networks Note 1 to entry: A base station comprises the hardware,

35、 including transceivers, necessary to transmit and receive radio signals. Base stations with integrated antennas, base stations with connectors for external antennas and base stations intended for use with external antennas not supplied by the same manufacturer are covered. Note 2 to entry: Examples

36、 of BS equipment include base stations for mobile communications, radio-relays, wireless local area network access points, base stations for cordless telephony, etc. that are not normally used in close proximity (i.e. within 20 cm) to the human body. Note 3 to entry: Examples of wireless telecommuni

37、cations networks include those used in mobile telecommunication systems according to ITU-R M.12241 “Vocabulary of terms for International Mobile BS EN 50385:2017EN 50385:2017 (E) 5 Telecommunications (IMT)”, wireless local area networks, public safety networks and fixed wireless systems (including r

41、considerations, frequency range of interest going from 110 MHz to 100 GHz 3.9 reference levels (or derived reference levels) levels which are provided for practical exposure assessment purposes and which are derived from basic restrictions Note 1 to entry: Respect of the reference level will ensure

42、respect of the relevant basic restriction. If the reference level is exceeded, it does not necessarily follow that the basic restriction will be exceeded. 3.10 worker person exposed to electromagnetic fields under the conditions defined in Directive 2013/35/EU 4 Exposure conditions RF exposure from

43、the product which meets the limits for general public exposure as given in this document (Clause 5) will automatically meet the limits for workers without further testing. RF exposure from the product which meets the limits for workers will not necessarily meet the limits for the general public and,

44、 unless RF exposure conditions are restricted to workers when at work, equipment shall also be tested against general public limits. RF exposure conditions restricted to workers when at work shall have this condition clearly identified in the product documentation. This condition shall be identified

45、 in the test report. All intended operating conditions as well as the reasonably foreseeable conditions of human exposure from the product shall be taken into account in the evaluation. The reasonably foreseeable conditions of exposure should be based on realistic exposure and/or installation parame

47、essment of general public exposure from the product, the relevant limits specified as basic restrictions, in Council Recommendation 1999/519/EC Annex II Table 1, or reference levels, in Council Recommendation 1999/519/EC Annex III Table 2, and the accompanying notes to these tables, shall be applied

48、. For the assessment of worker exposure from the product, the relevant limits specified as exposure limit values, in Directive 2013/35/EU Annex III Tables A.1 and A.3, or action levels in Directive 2013/35/EU Annex III Table B1, and the accompanying notes to these tables, shall be applied. 6 Evaluat
