32、evaluation method for determining the electromagnetic fields in the space around the equipment mentioned in the scope, and defines standardized operating conditions and measurement distances. This standard is designed to assess, by measurements and/or calculations, electromagnetic (EM) fields and th

33、eir potential effect on the human body by reference to exposure levels of the general public given by ICNIRP:1998 11), IEEE C95.1:2005 and IEEE C95.6:20022. The exposure levels with which to comply are basic restrictions (both ICNIRP- and IEEE-based). NOTE 1 Maximum permissible exposure levels (IEEE

34、-based) or reference levels (ICNRIP-based) are not used. Based on the lighting equipment operating properties, the frequency range of the applicable basic restrictions can be limited as follows: induced current density between 20 kHz to 10 MHz; specific absorption rate (SAR) between 100 kHz to 300 M

35、Hz; power density is outside the scope. NOTE 2 Operating frequencies of lighting equipment are higher than 20 kHz to avoid audible noise and infrared interference. Frequency contributions above 300 MHz can be neglected. This standard is not meant to supplant definitions and procedures specified in e

36、xposure standards, but it is aimed at supplementing the procedure already specified for compliance with exposure. The exposure limits given in Annex C (informative) are for information only, do not comprise an exhaustive list and are valid only in certain regions of the world. It is the responsibili

37、ty of users of this standard to ensure that they use the current version of the limit values specified by the applicable national authorities. 1)Figures in square brackets refer to the Bibliography.

38、OMAGNETIC FIELDS 1 Scope This International Standard applies to the assessment of lighting equipment related to human exposure to electromagnetic fields. The assessment consists of the induced current density for frequencies from 20 kHz to 10 MHz and the specific absorption rate (SAR) for frequencie

39、s from 100 kHz to 300 MHz around lighting equipment. Included in the scope of this standard are: all lighting equipment for general lighting with a primary function of generating and/or distributing light intended for illumination purposes, and intended either for connection to the low voltage elect

40、ricity supply or for battery operation; used indoor and/or outdoor. General lighting equipment means all industrial, residential and public and street lighting; lighting part for general lighting of multi-function equipment where one of the primary functions of this is illumination; independent auxi

41、liaries exclusively for the use with lighting equipment. Excluded from the scope of this standard are: lighting equipment for aircraft and airfields; lighting equipment for road vehicles; (except lighting used for the illumination of passenger compartments in public transport) lighting equipment for

42、 agriculture; lighting equipment for boats/vessels; photocopiers, slide projectors; apparatus for which the requirements of electromagnetic fields are explicitly formulated in other IEC standards; NOTE The methods described in this standard are not suitable for comparing the fields from different li

43、ghting equipment. This standard does not apply to built-in components for luminaires such as electronic control gear. 2 Normative references The following referenced documents are indispensable for the application of this document.
