IEC/IEEE 62209-1528:2020 – Assessment of Human Exposure to RF Fields from Wireless Devices

Measurement Procedure for the Assessment of Specific Absorption Rate of Human Exposure to Radio Frequency Fields from Hand-Held and Body-Mounted Wireless Communication Devices – Part 1528: Human Models, Instrumentation, and Procedures (Frequency Range of 4 MHz to 10 GHz)

This international standard, jointly developed by IEC and IEEE and published in September 2026, lays out comprehensive testing procedures for the measurement of specific absorption rate (SAR)—the rate at which RF energy is absorbed in human tissue. Designed to evaluate devices like mobile phones, tablets, wearable electronics, body-worn sensors, and even wireless power transfer systems, the standard codifies best practices for reproducible, repeatable, and conservative exposure assessments.

Scope and Objectives

Applicable Devices: Mobile phones, cordless microphones, push-to-talk radios, laptop transmitters, wearables, and accessories operating between 4 MHz and 10 GHz. Wireless power transfer devices above 4 MHz are also included. Implanted medical devices are excluded.
Target Demographics: Procedures address exposure for a broad population spectrum, including children, ensuring inclusive safety evaluation.
Test Scenarios: Coverage includes devices used at the ear, on the face, worn on the body or limbs, devices with accessories, and those embedded in garments. Both single and multi-antenna configurations are in scope, with proximity up to 200 mm from the body.

Key Requirements and Specifications

Phantom Models: Utilizes tissue-equivalent physical models of the head and torso, including application-specific configurations for various device types. Detailed specifications for phantoms (e.g., head, flat, wrist) and media recipes ensure measurement fidelity.
SAR Measurement Protocols: Procedures for conservative peak spatial-average SAR (psSAR) using probes with high isotropy, automated scanning systems, and calibrated readout electronics. Protocols delineate preparations, positioning, operating modes, frequency/channel considerations, and test reduction strategies.
Extended Frequency Range: Now spans from 4 MHz (covering low-frequency wireless power transfer) to 10 GHz (encompassing latest RF technologies).
Testing of Proximity/Motion Sensors: Accommodates devices employing proximity sensors (to reduce transmitted RF power when close to the body) and motion sensors, including triggering distance and coverage area validations.
Fast SAR Testing and Reductions: Introduces accelerated procedures (Class 1 and 2 fast SAR) and data-driven test reduction methods to enhance throughput without sacrificing safety assurance.
Uncertainty Analysis: Comprehensive models and strict reporting on measurement uncertainty, including calibration, probe positioning, tissue medium variability, and device positioning.
Validation Procedures: System checks with reference dipoles, waveguides, meander dipoles, loop antennas, and computational validation for specific frequency bands, plus detailed phantom calibration.
Reporting and Documentation: Standardized requirements for measurement reports, uncertainty budgets, and test configurations, supporting transparent regulatory submissions.

Industry Impact & Compliance

How the New Standard Shapes the Field

With its rigorous methodologies and advanced test protocols, the IEC/IEEE 62209-1528:2020 standard significantly impacts:

Device Approval Pipeline: Regulators and national authorities will update approval procedures to reference this new edition, making conformance a pre-requisite for market entry.
Laboratory Operations: Accredited labs must upgrade equipment, update phantom models, and retrain staff. Enhanced fast SAR and test reduction methods mean higher throughput and greater cost-effectiveness.
Manufacturer Responsibilities: OEMs must align internal compliance programs and documentation to reflect the latest requirements, especially around sensor-enabled devices and extended frequency applications.
Downstream Supply Chain: Procurement teams gain clarity when sourcing RF-compliant components through standardized international criteria, supporting safer final products.

Compliance Considerations and Timelines

Transition Periods: Most jurisdictions will establish transition windows—devices certified under older editions may require recertification for new models or significant modifications after the cutover date.
Documentation: Measurement reports must clearly align with the standard’s reporting schema, including detailed uncertainty budgets, test setups, and device configurations.
Ongoing Surveillance: Certification bodies will increase scrutiny on laboratory validation records, especially for fast SAR and test reduction approaches.
