Overview

SIST EN 62226-3-1:2008/A1:2017 establishes standardized methods for calculating current density and internal electric field induced in the human body when exposed to electric fields in the low and intermediate frequency range. Developed by the Slovenian Institute for Standardization (SIST), this amendment aligns with the European standard EN 62226-3-1:2007/A1:2017 and the International Electrotechnical Commission (IEC 62226-3-1:2007/A1:2016). The standard focuses specifically on analytical and 2D numerical models for exposure to electric fields.

This document plays a crucial role in the assessment and management of human exposure to low-frequency electric fields and supports the development and application of health and safety guidelines by providing repeatable, science-based computational methods.

Key Topics

• Exposure Assessment: Methods to determine the effect of electric fields on the human body in the 1 Hz to 100 kHz frequency range. The standard emphasizes current density (J) and internal electric field (E) calculations.
• Analytical and Numerical Models: Describes both analytical solutions (such as for spheroids in uniform fields) and two-dimensional (2D) numerical models for simulating induced effects in anatomical regions, e.g., the neck and spinal cord.
• Conductivity Considerations: Internal electric field values are derived from current densities, factoring in human body tissue conductivity.
• Shape Factors and Conversion: Procedures for converting average current densities to localized tissue values and for computing shape factors relevant to varied body geometries.
• Basic Restrictions: Reference values for occupational and public exposure are cited, in terms of internal electric field and current density, to aid in safety compliance.

Applications

SIST EN 62226-3-1:2008/A1:2017 is designed for practical application in environments where people may be exposed to artificial or naturally occurring low and intermediate frequency electric fields. Key use cases include:

• Health and Safety Assessments: Providing a scientific basis for evaluating compliance with exposure limits in workplaces, public spaces, and residential areas.
• Design of Electrical Installations: Informing the safe placement and operation of high-voltage equipment, power lines, and industrial machinery.
• Regulatory Compliance: Supporting organizations and authorities in adhering to international exposure guidelines, such as those issued by ICNIRP.
• Research and Development: Underpinning biomedical and engineering studies involving electromagnetic field (EMF) interactions with the human body.

By standardizing models and calculation methods, the document facilitates interoperability and clarity across international and multidisciplinary teams.

Related Standards

This standard is closely related to other documents dealing with electromagnetic field exposure and measurement:

• IEC 62226 series: Provides a comprehensive framework for exposure assessment to both electric and magnetic fields across varying frequencies and scenarios.
• ICNIRP Guidelines (2010): Offers the principal international exposure limits for electric and magnetic fields from 1 Hz to 100 kHz and is referenced for health-based restriction values.
• EN 62226-3-1:2007 and Amendments: The European counterpart ensures harmonized application throughout EU member states.

For professionals working in electromagnetic field safety, bioelectromagnetics, or electrical engineering, adherence to SIST EN 62226-3-1:2008/A1:2017 ensures state-of-the-art assessment methodology and supports global consistency in human exposure evaluation.
