IEC 63203-402-3:2024 PDF

Overview

IEC 63203-402-3:2024 sets an international standard for evaluating the performance and accuracy of fitness wearables that measure heart rate via photoplethysmography (PPG) sensors. Developed by the International Electrotechnical Commission (IEC), this standard defines terms, establishes a comprehensive measurement protocol, and prescribes test methods designed to ensure that heart rate monitoring devices (HRMDs) deliver reliable and consistent results. The document is applicable to various wearable devices that claim to report heart rate but does not address medical devices governed by the IEC 60601 or ISO 80601 series.

Key Topics

• Scope and Definitions: Clarifies essential concepts such as heart rate, pulse rate, body mass index (BMI), and photoplethysmogram. Emphasizes the common interchangeability yet distinction between heart rate (cardiac contractions) and pulse rate (arterial pressure sensed by pulse).
• Test Methods and Protocols:
  • PPG Simulator Testing: Outlines the use of a PPG simulator to replicate physiological conditions, allowing for systematic evaluation of device accuracy at set frequencies.
  • Comparative Testing: Participants wear both a PPG-based wearable and a certified reference ECG device to compare readings during various physical activities (e.g., sedentary, walking, jogging, running).
• Participant Criteria: Stipulates participant diversity in skin tone, BMI range, age, and gender to assess device performance across a realistic spectrum of users. Ensures test validity and inclusivity.
• Testing Environments: Requires that devices be tested in environments with representative ambient light, temperature, and potential interference to simulate real-world use.
• Accuracy Determination: Accuracy is evaluated using the mean absolute percentage error (MAPE), with a requirement that readings fall within ±10% of reference measurements for passing.

Applications

• Product Development & Quality Assurance: Provides wearable tech manufacturers with standardized protocols to assess and improve heart rate measurement accuracy during product design, development, or quality control processes.
• Regulatory Compliance: Enables industry stakeholders to demonstrate compliance with globally recognized standards, supporting international market access and consumer trust.
• Performance Benchmarking: Facilitates comparative analysis across various wearable devices, establishing a basis for product claims and marketing.
• Research & Clinical Studies: Offers a reliable framework for evaluating devices in academic or non-clinical health research, where consistency in heart rate data is critical.
• Consumer Assurance: Assures end-users and organizations that products tested according to IEC 63203-402-3:2024 meet established accuracy benchmarks for fitness and wellness purposes.

Related Standards

• IEC 63203 Series: This standard is part of the broader IEC 63203 series, which covers various aspects of wearable electronic devices and technologies.
• IEC 60601 Series: Pertains to the medical-grade electrical equipment standards; devices intended for clinical or diagnostic use should refer to this series.
• ISO 80601 Series: Focuses on medical devices used for assessing physiological functions.
• IEC Electropedia: For terminology consistency, refer to the IEC's online electrotechnology dictionary.
