IEC 62232:2022

Overview

IEC 62232:2022, published by the International Electrotechnical Commission (IEC), specifies standardized methods for determining radio-frequency (RF) field strength, power density, and specific absorption rate (SAR) in the vicinity of base stations. The purpose of this standard is to enable the accurate evaluation of potential human exposure to RF electromagnetic fields generated by products or equipment under test (EUT) operating in the range of 110 MHz to 300 GHz. IEC 62232:2022 provides common evaluation processes and criteria for product compliance, installation assessment, and in-situ measurement scenarios, but does not define exposure limits, which must be sourced from national regulations or referenced guidelines.

Key Topics

• Scope of Evaluation
  • Applies to base stations and other EUTs emitting RF in the 110 MHz to 300 GHz frequency range.
  • Excludes evaluation of current density.
• Assessment Methods
  • Specifies measurement and computational methods for determining RF field strength, power density, and SAR.
  • Guidance is provided for field measurements, laboratory testing, and computational simulation.
• Compliance Assessment
  • Outlines processes for demonstrating product compliance during design, installation, or operation.
  • Includes the establishment and verification of compliance boundaries around base stations.
• In-Situ Exposure Assessment
  • Procedures for evaluating real-world RF exposure in locations accessible to the general public or workers.
  • Includes spatial and temporal averaging methods to ensure representative exposure values.
• Reporting and Uncertainty
  • Requirements for documentation and reporting of evaluation results.
  • Guidance for estimating and applying uncertainty in exposure assessments.
• References to Exposure Limits
  • Exposure limits are not specified; users are directed to applicable standards such as ICNIRP-2020, ICNIRP-1998, IEEE C95.1, and Safety Code 6.

Applications

IEC 62232:2022 serves as a critical reference for:

• Manufacturers of Base Stations
  • Ensures product design meets regulatory RF exposure compliance by implementing standardized assessment methods.
• Network Operators and Installers
  • Supports the safe installation of RF transmitters and infrastructure by evaluating site-specific exposure scenarios.
  • Assists in site planning and mitigation measures to maintain compliance with local RF exposure regulations.
• Accredited Testing Laboratories
  • Provides methodologies for conducting both laboratory and in-situ measurements as part of product certification and ongoing compliance programs.
• Regulatory Authorities
  • Offers a harmonized basis for RF exposure assessment supporting national and international regulatory frameworks.
• Occupational Health and Safety Professionals
  • Facilitates risk assessments for workers and the public near RF-emitting infrastructure.
