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 frequency range from 1 Hz to 6 MHz with respect to induced electric shock phenomena, for electroheating (EH) based treatment technologies and for electromagnetic processing of materials (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 or electromagnetic processing in general result from the joint application of the General Requirements specified in IEC 60519-1:2015 and Particular Requirements covering specific types of installations or equipment. This technical specification complements the General Requirements and applies to internal frequency converters for creating high or low DC voltages, and to processing frequencies.

Induced electric shock phenomena dealt with in this technical specification are caused by the alternating 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. Simplified hazard assessment procedures apply for situations when only fingers, hands and/or extremities 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.
