IEC 62764-1-2022 PDF

Full title and description

Measurement procedures of magnetic field levels generated by electronic and electrical equipment in the automotive environment with respect to human exposure - Part 1: Low-frequency magnetic fields. This international standard specifies measurement methodology, standardized operating conditions and recommended measurement volumes/surfaces for assessing human exposure to low-frequency magnetic fields (1 Hz to 100 kHz) produced by passenger cars and light commercial vehicles (categories M1 and N1). For plug-in vehicles it includes vehicle-supplied EVSE and associated cables provided by the manufacturer but excludes external charging stations.

Abstract

IEC 62764-1:2022 defines a repeatable measurement procedure to evaluate low-frequency magnetic field exposures inside selected automotive environments. It addresses multiple magnetic-field sources, specifies standardized vehicle operating conditions, and provides recommended measurements to support comparison with applicable exposure limits. The document replaces the 2019 technical specification and is intended for application to any type of engine or internal energy source.

Scope

This part of IEC 62764 applies to the assessment of human exposure to low-frequency magnetic fields generated by electronic and electrical equipment inside automotive environments for passenger cars and light commercial vehicles of categories M1 and N1 (as referenced to relevant ECE definitions). It covers the frequency range from 1 Hz to 100 kHz, provides standardized operating conditions and defines measurement volumes and/or surfaces and recommended measurement procedures for evaluating exposures from multiple sources inside the vehicle. The scope explicitly excludes intentionally transmitting radio‑frequency antennas and external charging stations (although EVSE and cables supplied with the vehicle are included). It is applicable regardless of vehicle powertrain type (conventional, hybrid, battery electric).

Key topics and requirements

• Standardized measurement methodology for low-frequency magnetic-field levels in selected automotive compartments.
• Frequency coverage and measurement band: 1 Hz to 100 kHz.
• Definition of measurement volumes and/or surfaces and recommended probe positions to capture representative exposures from multiple sources.
• Prescribed vehicle operating conditions and test sequences to ensure repeatability and comparability of results.
• Guidance on instrumentation, measurement uncertainty considerations and recommended reporting to support assessment against applicable exposure limits.
• Clarification of what is in/out of scope (e.g., exclusion of charging-station equipment external to the vehicle).

Typical use and users

Used by automotive OEMs, test and measurement laboratories, EMC and human-exposure engineers, regulatory bodies, occupational health teams and research organizations. Typical applications include pre-compliance design verification, type approval support, in‑service evaluation of passenger and occupant exposure, and comparative testing across vehicle variants and accessory configurations. National standards bodies and certification agencies also adopt this IEC text as a basis for regional implementation.
