Overview
IEC 63517:2026, titled Wearable Electronic Textiles - Test Method for Performance of Heating Products - Heating Temperature and Power Consumption, is an international standard focused on defining a rigorous, repeatable approach for testing the heating performance of wearable heating e-textile products. This standard is developed by the International Electrotechnical Commission (IEC) in collaboration with the International Organization for Standardization (ISO).
The scope of IEC 63517:2026 covers measurement methods for heating temperature and power consumption in wearable heating garments such as jackets and vests incorporating electronic textile parts and portable batteries. It deliberately excludes gloves and footwear, as well as safety aspects and the performance of the portable battery. For those, relevant safety standards such as IEC 60335-2-17 and IEC 62368-1 should be applied.
Key Topics
- Test Methods for Heating Performance: Procedures for assessing both the heating temperature and power consumption of wearable e-textile heating products.
- Applicable Products: Focuses on garments made of electronic textile parts for heating, such as jackets and vests, alongside conventional textile materials.
- Measurement Principles:
- Identification of the heating areas using infrared thermography
- Selection of the hottest measuring points for accurate temperature profiling
- Recording temperature stability over a defined test duration
- Simultaneous measurement of current, voltage, and calculation of power consumption
- Test Equipment and Materials:
- Use of thermometers (e.g., thermocouples, thermistors), voltmeters, ammeters, and infrared cameras meeting relevant ISO and IEC standards.
- Thermal insulation materials specified to ensure controlled, repeatable test conditions.
- Environmental Conditions: Conditioning and testing under standardized temperature and humidity, as defined in ISO 139.
Applications
The application of IEC 63517:2026 is critical for manufacturers, testing laboratories, and quality assurance professionals working with wearable heating textiles. Key use cases include:
- Product Development & Design: Enables engineers and designers to objectively benchmark and optimize heating performance in e-textiles, ensuring products meet customer expectations for warmth and energy efficiency.
- Quality Control & Verification: Allows manufacturers and third-party labs to verify consistent product performance across production batches, supporting claims related to heating efficacy and battery life.
- Market Access & Certification: Using this standardized method helps ensure products meet international requirements for interoperability and performance, aiding in regulatory compliance and market acceptance.
- R&D and Benchmarking: Facilitates the development of innovative textile heating solutions and the comparison of different materials, structures, or power management strategies under standardized conditions.
The test results, presented as average, maximum, and minimum heating temperatures and power consumption values, provide a transparent performance profile essential for both technical documentation and consumer information.
