27、f this generic standard is to provide a route for evaluation of equipment used by workers against limits on human exposure to electric, magnetic and electromagnetic fields, and induced and contact current when it is put into service in its operational environment, and also for in situ or post-market

28、 evaluation of such equipment. The frequency range covered is 0 Hz to 300 GHz. This standard applies to equipment for which no dedicated harmonized putting-into-service or in situ product standard regarding worker exposure to electromagnetic fields exists. If such a standard does exist then it shoul

29、d be used. At the time of writing there is one applicable standard, for base station equipment, and this should be used for putting-into service or in situ assessment of such equipment with respect to worker exposure to electromagnetic fields: EN 50401:2017. Product standard to demonstrate the compl

30、iance of base station equipment with radiofrequency electromagnetic field exposure limits (110 MHz - 100 GHz), when put into service The current list of standards harmonized under each Directive should be consulted at the time of use of this standard.

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 b

37、2013/35/EU BS EN 50664:2017EN 50664:2017 (E) 5 4 Exposure conditions Equipment intended only for use by workers when 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

38、the reasonably foreseeable conditions of human exposure from the equipment shall be taken into account in the evaluation. The reasonably foreseeable conditions of exposure should be based on realistic exposure and/or installation parameters representative of all readily-predictable human and system

39、behaviour such as the duration of exposure, time varying of transmitted power, simultaneously operated frequency bands and time averaging as defined in normative limits. 5 Limits The exposure restrictions in Directive 2013/35/EU shall be applied, with a statement as to whether the limit chosen provi

40、des 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 6.2. 6 Evaluation of compliance 6.1 A priori compliant equipment The equipment is a priori compliant with the requiremen

41、ts of this standard (either putting into service or in situ, or both) if it is listed as a priori compliant in Table 1 of EN 50499:2008, and no further assessment is necessary. NOTE For item T1.2 of Table 1 of EN 50499:2008, compliance with this standard is only ensured if a harmonized EMF standard

42、has been used for CE marking for general public use. The basis for this is that if equipment meets general public limits then it will meet worker limits and that that will be the case even for simultaneous exposure from multiple pieces of equipment provided they all have been shown to be compliant t

43、o general public limits. 6.2 General Unless equipment is a priori compliant as defined in 6.1 of this standard or there exists an equipment-specific basic standard as described in 6.2 of this standard, measurements, calculations and other assessments to demonstrate compliance shall be made according

44、 to EN 62311:2008, 5.7, t. EN 62311:2008 contains procedures for assessing compliance and combining multifrequency exposures.

48、 in all cases rather than any conflicting usage or exposure conditions described in the standards listed in Table 1. 6.3 Putting into service When the equipment is put into service in its operational environment and operated in accordance with the manufacturers specification, it fulfils the requirem

49、ents of this standard if workers are not, under any reasonably foreseeable conditions, able to encounter any location where the total exposure to electromagnetic fields may exceed the limits chosen in Clause 5, taking account of contributions to exposure from all other electromagnetic field sources in the vicinity in addition to the exposure contribution from the product. 6.4 In situ When the equipment is used in its operational environment (“in situ”) in accordance with the manufacturers specification, it fulfils the requ
