IEC 60747-14-10:2019

Overview

IEC 60747-14-10:2019 establishes key performance evaluation methods for wearable glucose sensors based on semiconductor technology. Developed by the International Electrotechnical Commission (IEC), this standard is specifically applicable to wearable electrochemical-glucose sensors, without restrictions on device technology or size. The document defines essential terminology, symbols, characteristic parameters, and robust test procedures, ensuring consistent and reliable assessment of sensor function. Its scope addresses both consumer and manufacturer needs, helping to guide quality assurance, regulatory compliance, and product development in the rapidly expanding field of mobile health monitoring.

Key Topics

• Comprehensive Definitions: The standard provides precise definitions for terms such as electrochemical-glucose sensor, electrode types (working, counter, reference), and sensor insertion types (implant, patch).
• Characteristic Parameters: It details core parameters including:
  • Sensitivity – Relationship between current and glucose concentration
  • Selectivity – Ability to distinguish glucose from other substances
  • Response Time – Time for sensor output to stabilize after a change in glucose
  • Linearity – Proportionality between glucose concentration and sensor output
  • Repeatability & Reliability – Measurement precision under short and long-term conditions
  • Limit of Detection – Smallest reliably detectable glucose value
  • Accuracy & Reproducibility – Degree to which measurements match true glucose values across different conditions
  • Life-time – Duration of sensor effectiveness
• Testing Protocols: The document specifies standardized test methods:
  • In Vitro Evaluation: Controlled laboratory testing for sensitivity, selectivity, and more
  • Preclinical Evaluation: Animal studies and robust testing prior to clinical use
  • Clinical Evaluation: Human trials to demonstrate safety and performance
• Marking and Identification: Requirements for traceability, including manufacturer, serial number, and year/month of manufacture.
