BS PD IEC/TS 62997:2017

BS PD IEC/TS 62997:2017 specifies the characteristics of external magnetic nearfields,computations of and requirements on induced electric fields in body tissues in the frequencyrange from 1 Hz to 6 MHz with respect to induced electric shock phenomena, forelectroheating (EH) based treatment technologies and for electromagnetic processing ofmaterials (EPM). The phenomena include specific absorption rates with time integration.NOTE The overall safety requirements for the various types of equipment and installations for electroheating orelectromagnetic processing in general result from the joint application of the General Requirements specified inIEC 60519-1:2015 and Particular Requirements covering specific types of installations or equipment. This technicalspecification complements the General Requirements and applies to internal frequency converters for creating highor low DC voltages, and to processing frequencies.Induced electric shock phenomena dealt with in this technical specification are caused by thealternating magnetic nearfield external to a current-carrying conductor or permeable object,inducing an electric field in a part of the body in the vicinity of the conductor.Relaxed criteria compared with the general basic restrictions for exposure apply. Simplifiedhazard assessment procedures apply for situations when only fingers, hands and/orextremities are in the magnetic nearfield.This technical specification does not apply to equipment within the scope of IEC 60519-9. i.e.equipment or installations for high frequency dielectric heating.Cross References:IEC 60417IEC 60519-1:2015IEC 60050IEEE C95.1:2005IEC 60519IEEE C95.6:2002IEEE C95.3.1:2010IEEE C95.1a:2010IEC 60050-161:1990IEC 62110:2009IEC 61140:2016IEC 60519-9:2005 IEC 62209-2:2010IEC TS 62996:2017IEC TS 60479-2:2007IEC 60519-6:2011EN 50445:2008EN 50444:2008IEC 60050-903:2013 ED1IEC 62822-2:2016IEC 60050-841:2004 Ed 2IEC 62479:2010IEC 62226-2-1:2004 Ed 1
