IEC 62232:2025 pdf download,Determination of RF field strength, power density and SAR in the vicinity of base stations for the purpose of evaluating human exposure.

IEC 62232:2025 outlines methodologies for measuring RF field strength, power density, and specific absorption rate (SAR) in the vicinity of base stations (BS) to assess human exposure to radiofrequency (RF) radiation. This standard is essential for ensuring that exposure levels remain within safe limits.

The document includes several key considerations: a) It addresses intentionally radiating base stations that transmit using one or more antennas across multiple frequencies within the range of 110 MHz to 300 GHz. b) It takes into account the influence of ambient RF sources on exposure levels, specifically within the frequency range of 100 kHz to 300 GHz. c) The standard specifies evaluation methods for RF exposure compliance assessments, which include:

1. Product Compliance: Determining compliance boundary information for a base station product prior to its market introduction.
2. Product Installation Compliance: Assessing total RF exposure levels in accessible areas from a base station and other relevant sources before the product is operational.
3. In-Situ RF Exposure Assessment: Measuring RF exposure levels in the vicinity of a base station installation after it has been activated.

d) The document outlines how to conduct RF exposure assessments based on actual maximum exposure levels. e) It describes various methodologies for measuring RF field strength, power density, and SAR, providing guidance on their applicability for both in-situ evaluations of installed base stations and laboratory assessments. f) Surveyors are instructed on how to establish specific evaluation procedures tailored to their assessment objectives. g) The standard offers guidance on reporting, interpreting, and comparing results from different evaluation methods, and, when necessary, making justified decisions regarding compliance with limit values. h) Additionally, it provides methods for assessing RF exposure from base stations utilizing time-varying beam-steering technologies, such as new radio (NR) base stations employing massive multiple input multiple output (MIMO) systems.

By establishing these comprehensive guidelines, IEC 62232:2025 aims to enhance the safety and reliability of RF exposure assessments, ensuring that human health is adequately protected in environments where base stations operate.
