BS PD IEC/TS 62997 – Industrial electroheating and electromagnetic processing equipment. Evaluation of hazards caused by magnetic nearfields from 1 Hz to 6 MHz

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.
