BS EN 50647:2017 provides a general procedure to assess workers' exposure to electric and magnetic fields (EMF) in work places associated with the production, transmission and distribution of electric energy, and to demonstrate compliance with exposure limit values and action levels as stated in the Council and European Parliament 'EMF' Directive 2013/35/EU [11].NOTE 1 The Council and European Parliament Directive 2013/35/EU will be transposed into national legislation in all the EU member countries. It is important that users of this standard consult the national legislation related to this transposition in order to identify the national regulations and requirements. These national regulations and requirements may have additional requirements that are not covered by this standardIt has the role of a specific workplace standard. It takes into account the non-binding application guide for implementing the EMF Directive [10] and it defines the assessment procedures and compliance criteria applicable to the electric industry.The frequency range of this standard covers from DC to 20 kHz, which is sufficient to include the power frequency used for electric power supply systems throughout Europe (50 Hz) and the various harmonics and inter-harmonics occurring in the supply system. In this extremely low frequency range, electric and magnetic fields are independent and, therefore, they both have to be addressed in the exposure assessment.NOTE 2 Electrical companies also use radio frequency transmissions to operate and maintain their networks and power plants. Similarly, other exposures to EMF may occur during maintenance operations, for instance, due to the use of hand-held electrical tools. All these EMF sources are outside the scope of this standard.NOTE 3 Regarding EMF in the low frequency range, the scientific basis of the EMF directive is the ICNIRP health guidelines published in 2010 [13]. Reference is made to this scientific basis when necessary for justifying or clarifying some of the technical statements of the present document.Cross References:IEC 61786-1:2013EN 50527-2-1:2016IEC 61786-2:2014EN 61786-1 (IEC 61786-1:2013) ASEN 50527-1:2016 CIGRE W.G. 36.01CIGRE WG C4.25IEEE STD C95.6EN 50341-1:2012EN 50160:2010IEC 62226-2-1:2004 Ed 1EN 62226-2-1 (IEC 62226-2-1:2004) ASEN 62311(IEC 62311:2007Mod) ASAll current amendments available at time of purchase are included with the purchase of this document.
