Full title and description

Industrial electroheating and electromagnetic processing equipment - Evaluation of hazards caused by magnetic nearfields from 1 Hz to 6 MHz. IEC TS 62997:2017 provides guidance and requirements for assessing hazards from magnetic nearfields produced by electroheating and electromagnetic processing equipment, including methods to compute induced electric fields and criteria for shock and tissue-heating effects.

Abstract

This Technical Specification defines the characteristics of external magnetic nearfields and specifies computations and requirements on induced electric fields in body tissues in the frequency range 1 Hz to 6 MHz for electroheating (EH) and electromagnetic processing of materials (EPM). It addresses induced electric-shock phenomena, specific absorption rate (SAR) considerations (including time integration), simplified assessment approaches for fingers/hands/extremities, and relationships to the IEC 60519 general requirements for electroheating.

Scope

The specification applies to evaluation of hazards caused by magnetic nearfields external to current-carrying conductors or permeable objects used in electroheating and electromagnetic processing. It covers induced electric-field calculations and safety requirements in the band 1 Hz–6 MHz, with relaxed criteria and simplified procedures for situations involving only extremities (fingers, hands). It does not apply to equipment within the scope of IEC 60519-9 (high-frequency dielectric heating).

Key topics and requirements

• Definition and characterization of magnetic nearfields produced by EH/EPM equipment in 1 Hz–6 MHz.
• Methods to compute induced electric fields in body tissues and associated numerical/analytical approaches.
• Limits and requirements addressing immediate nerve and muscle reactions (induced shock effects).
• SAR and tissue-heating considerations, including time-integration rules for exposure assessment.
• Uncertainties, safety factors, and guidance on numerical inaccuracies in induced-field calculations.
• Risk-group classification and marking/warning requirements; simplified assessment for hands/fingers/extremities.

These topics reflect the Technical Specification’s table of contents and normative focus on induced-field evaluation and practical hazard assessment.

Typical use and users

Used by designers, safety engineers, test laboratories, and regulatory bodies involved with industrial electroheating or electromagnetic processing equipment. Typical applications include evaluation of occupational exposure near induction heaters, melting and processing furnaces, electromagnetic forming equipment, and other industrial devices that generate strong magnetic nearfields. The document is used for risk assessment, marking/warning decisions, and to complement the general safety requirements given in IEC 60519 series.

Related standards
