23、icting with the EN have to be withdrawn (dow) 2020-09-11 This European Standard has to be read in conjunction with EN 62311:2008 “Assessment of electronic and electrical equipment related to human exposure restrictions for electromagnetic fields (0 Hz to 300 GHz)”. Attention is drawn to the possibil

24、ity that some of the elements of this document may be the subject of patent rights. CENELEC shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CENELEC by the European Commission and the European Free Trade Association

25、 and, and supports essential requirements of the Radio Equipment Directive 2014/53/EU (M/536) and the Low Voltage Directive 2014/35/EU (M/511).

26、1 Scope This European Standard applies to electronic and electrical equipment for which no dedicated harmonized product- or product family standard, or standard relating to low power equipment, regarding human exposure to electromagnetic fields exists. If such a standard does exist then it shall be

27、used and this standard shall not. Annex A lists such harmonized standards available at the time of writing This list may change with time. The current list of standards harmonized under each Directive should be consulted at the time of use of this standard. The object of this generic standard is to

28、provide a route for evaluation of such equipment against limits on human exposure to electric, magnetic and electromagnetic fields, and induced and contact current. The frequency range covered is 0 Hz to 300 GHz. This standard is intended to cover both intentional and non-intentional radiators. NOTE

29、 1 Other standards can apply to products covered by this document. In particular, this document is not designed to evaluate the electromagnetic compatibility with other equipment; nor does it reflect any product safety requirements other than those specifically related to human exposure to electroma

30、gnetic fields. NOTE 2 This standard addresses only human exposure from the specific equipment under evaluation. There is an applicable putting-into service/in situ standard for equipment used by workers when at work: EN 50664:2017. Generic standard to demonstrate the compliance of equipment intended

31、 for use only by workers with limits on human exposure to electromagnetic fields (0 Hz - 300 GHz), when put into service or in situ. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. F

32、or dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 62311:2008, Assessment of electronic and electrical equipment related to human exposure restrictions for electromagnetic fields (0 Hz - 30

33、0 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, L199, of 1999-7-30, p.59-70 Directive 2013/35/EU of 26 June 2013, on the minimum health and safety requirements regarding the

34、exposure of workers to the risks arising from physical agents (electromagnetic fields). Official Journal, L179, of 2013-6-29, p. 121 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 action levels levels provided for practical exposure assessme

35、nt purposes. They are derived from exposure limit values. 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 exposu

36、re of the general public to electric, magnetic and electromagnetic fields that are based directly on established health effects and biological considerations 3.3 exposure limit values restrictions on exposure of workers to electric, magnetic and electromagnetic fields that are based directly on esta

37、blished health effects and biological considerations BS EN 50665:2017EN 50665:2017 (E) 5 3.4 reference levels (or derived reference levels) levels provided for practical exposure assessment purposes. They are derived from basic restrictions. Respect of the reference level will ensure respect of the

38、relevant basic restriction. If the reference level is exceeded, it does not necessarily follow that the basic restriction will be exceeded 4 Exposure conditions Equipment which meets the limits for general public exposure as given in this document (Clause 5) will automatically meet the limits for wo

39、rkers without further testing. Equipment which meets the limits for workers will not necessarily meet the limits for the general public and, unless intended only for workers use when at work, equipment shall also be tested against general public limits. Equipment intended only for use by workers whe

40、n at work shall have this condition clearly identified in the user instructions. This use condition shall be identified in the test report. All intended operating conditions as well as the reasonably foreseeable conditions of human exposure from the equipment shall be taken into account in the evalu

41、ation. The 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 ba

42、nds and time averaging as defined in normative limits. 5 Normative limits For equipment intended for use by the general public the relevant exposure restrictions in Council Recommendation 1999/519/EC shall be applied. For equipment intended only for use by workers when at work, the relevant exposure

43、 restrictions in Directive 2013/35/EU shall be applied, with a statement as to whether the limit chosen provides protection against health effects or sensory effects or both. Details of where limits are to be found in Directive 2013/35/EU and how they relate to test methods, are given in 6.3. 6 Eval

44、uation of compliance 6.1 General The measurements and calculations to demonstrate equipment compliance shall be made according to EN 62311:2008, Clauses 4 and 5. The general considerations as defined in EN 62311:2008, Clauses 4 and 5 shall apply to all equipment. 6.2 Assessment of devices which emit

45、 multiple frequencies In situations where simultaneous exposure to fields of different frequencies occurs, the possibility that these exposures will be additive in their effects shall be considered. Assessment based on such additive effects shall be performed separately for each effect in accordance

46、 with Tables 1 and 2 in Clause 6.3 of this standard. 6.3 Correspondence between limits and test procedures EN 62311:2008 contains procedures for assessing compliance and combining multifrequency exposures in terms of primary exposure restrictions (basic restrictions and exposure limit values) or der

47、ived levels (reference levels or action levels). Table 1 gives correspondence between worker limits, test procedures and multifrequency exposure approaches. Table 2 gives correspondence between general public limits, test procedures and multifrequency exposure approaches. BS EN 50665:2017EN 50665:20
