South Korea Launches New SAR Procedures for Wireless Devices

On August 23, 2024, the Korea Standards & Certification authority initiated an important public consultation through Circular No. 2024-71, focusing on the procedures for evaluating the Specific Absorption Rate (SAR) of wireless communication devices used near the human body. The SAR standard, which measures the rate at which energy is absorbed by the human body from electromagnetic fields, is critical for ensuring that wireless devices meet health and safety guidelines.

Key Changes in SAR Measurement Standards

This consultation addresses the proposed replacement of the existing standards for SAR evaluation:

  1. KS C 3370-2: This standard, covering the measurement procedures for the SAR of portable wireless devices used in close proximity to the human body, is slated for withdrawal.
  2. KS_C_NEW_2024_4501: The new standard, set to replace KS C 3370-2, will provide updated methods and procedures for evaluating SAR in wireless communication devices. This new standard is expected to streamline testing processes while aligning with global best practices for radiation safety.

The Importance of SAR Evaluation

SAR testing is essential in the design and certification of wireless devices such as smartphones, tablets, and other portable electronics that consumers use near their bodies. Regulatory bodies in many countries, including EU & US, require that devices meet specific SAR thresholds to ensure that electromagnetic radiation exposure remains within safe limits. As wireless technology continues to advance, updated SAR standards help manage the potential risks associated with increased device usage and new communication technologies.

Public Participation and Timeline

The public consultation, which opened on August 23, 2024, invites comments and input from stakeholders, industry experts, and the public. The consultation period will remain open until October 22, 2024, providing a platform for interested parties to review the proposed changes and submit their feedback.
