PD IEC/TS 62997 discusses industrial electroheating and electromagnetic processing equipment. PD IEC/TS 62997 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.
Induced electric shock phenomena dealt with in PD IEC/TS 62997 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.
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. PD IEC/TS 62997 complements the General Requirements and applies to internal frequency converters for creating high or low DC voltages, and to processing frequencies.
PD IEC/TS 62997 on Industrial electroheating and electromagnetic processing equipment is useful for:
An external alternating magnetic flux can induce electric fields inside the human body. Such induced fields constitute an important category of possible hazards. PD IEC/TS 62997 deals with the sub-category of non-radiating magnetic nearfields in the frequency range between 1 Hz and 6 MHz being the source of the induced electric fields. The primary focus is on technical applications in industrial electroheating and electromagnetic processing installations and equipment, with the applicable safety standards in the IEC 60519 series.
PD IEC/TS 62997 provides you with a volunteer test method for assessments of perception of immediate muscle and nerve reactions in fingers and hands at frequencies below 100 kHz. PD IEC/TS 62997 provides you with complete information for assessments. The methods in PD IEC/TS 62997 reduce costs to industry by being simple and direct. They are also realistic since the number of reported accidents or incidents caused by magnetic nearfields as addressed in PD IEC/TS 62997 specification is exceptionally few in relation to the occurrence of strong such fields in the industry.
