EN 50401:2017 includes the following significant technical changes with respect to EN 50401:2006: 1) the standard require
24、s that the assessment has to take into account all reasonably foreseeable operating conditions (Clause 4); 2) the standard covers equipment intended for use only by workers as well as equipment intended for use by the general public and different limits are given for each case (Clause 5). This docum
25、ent has been prepared under a mandate given to CENELEC by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For the relationship with EU Directive(s) see informative Annex ZZ, which is an integral part of this document. BS EN 504
26、01:2017EN 50401:2017 (E) 4 1 Scope This product standard is related to human exposure to radiofrequency electromagnetic 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 restr
27、ictions (directly or indirectly via compliance with reference levels) and the workers exposure limits values (directly or indirectly via compliance with action levels), when it is put into service in its operational environment. 2 Normative references The following documents, in whole or in part, ar
28、e normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 62232:2017, Determination of RF field strength, powe

30、99, 30.6.1999, p. 59-70) Directive 2013/35/EU of the European Parliament and of the Council of 26 June 2013 on the minimum health and safety requirements regarding the exposure of workers to the risks arising from physical agents (electromagnetic fields) (20th individual Directive within the meaning
31、 of Article 16(1) of Directive 89/391/EEC) and repealing Directive 2004/40/EC (Official Journal L 179, 29.6.2013, p. 121) 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 action levels levels which are provided for practical exposure assessmen
32、t purposes and which are derived from exposure limit values Note 1 to entry: 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 ambient fields backgr
33、ound electromagnetic fields in the frequency range from at least 100 kHz to 300 GHz other than the emissions from the EUT in the frequency range 110 MHz to 100 GHz 3.3 antenna device that serves as a transducer between a guided wave (e.g. coaxial cable) and a free space wave, or vice versa, and that
34、 can be used either to emit or to receive a radio signal Note 1 to entry: In the present standard, if not mentioned, the term antenna is used only for emitting antenna(s). 3.4 average emitted power time-averaged rate of energy transfer defined by: 21211taeptP P t dttt=() BS EN 50401:2017EN 50401:201
35、7 (E) 5 where t2 t1 is the averaging time, tavgdefined as a function of frequency in the Council Recommendation 1999/519/EC of 12 July 1999; P(t) is the power radiated by the antenna at the maximum duty cycle of the equipment at the maximum power setting of the equipment 3.5 base station BS fixed eq
36、uipment including the radio transmitter and associated antenna(s) as used in wireless telecommunications networks Note 1 to entry: A base station comprises the hardware, including transceivers, necessary to transmit and receive radio signals. Base stations with integrated antennas, base stations wit
37、h 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 of BS equipment include base stations for mobile communications, radio-relays, wireless local area network access points, base sta
38、tions 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 telecommunications networks include those used in mobile telecommunication systems according to ITU-R M.12241 “Vocabulary of terms for Interna
39、tional Mobile Telecommunications (IMT)”, wireless local area networks, public safety networks and fixed wireless systems (including radio-relay systems, point-to-point communication and point-to-multipoint communication according to ITU-R F.5924 “Vocabulary of terms for the fixed service” and ITU-R
40、F.13991 “Vocabulary of terms for Wireless Access”). Note 4 to entry: Equipment for radar, TV and radio broadcast services is not considered to be a BS. 3.6 basic restrictions restrictions on exposure of the general public to electric, magnetic, and electromagnetic fields that are based directly on e
41、stablished health effects and biological considerations 3.7 equivalent isotropic radiated power EIRP product of the radiofrequency input power to an antenna and the absolute gain of the antenna in a given direction 3.8 exposure limit values restrictions on exposure of workers to electric, magnetic a
42、nd electromagnetic fields that are based directly on established health effects and biological considerations 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
43、 of the reference level will ensure 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 BS
44、EN 50401:2017EN 50401:2017 (E) 6 4 Exposure conditions RF exposure from the product installation 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 installation w
45、hich meets the limits for workers will not necessarily meet the limits for the general public and, 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
46、this condition clearly identified in the product documentation. This condition shall be identified in the test report. All intended operating conditions as well as the reasonably foreseeable conditions of human exposure from the product installation shall be taken into account in the evaluation. The
47、 reasonably foreseeable conditions of exposure should be based on realistic exposure and/or installation parameters representative of all readily-predictable human and system behaviour such as the duration of exposure, time varying of transmitted power, simultaneously operated frequency bands and ti
48、me averaging as defined in normative limits. 5 Normative limits For the assessment of general public exposure from the product installation, the relevant limits specified as basic restrictions, in Council Recommendation 1999/519/EC Annex II Table 1, or reference levels, in Council Recommendation 199
49、9/519/EC Annex III Table 2, and the accompanying notes to these tables, shall be applied. For the assessment of worker exposure from the product installation, 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 Evaluation of compliance 6.1 General public exposure The product installation is deemed to comply with the applicable normative limits defin
