Overview
EN ISO 17971:2025 - Textiles: Smart textiles - Test method for determining the screen-touch properties of fabrics specifies a standardized test method to evaluate how fabrics interact with capacitive touchscreens. Published by CEN/ISO in 2025 and adopted as a European Standard (EN ISO 17971:2025), it applies to all fabric types intended to serve as an interface (for example, touchscreen-capable gloves, sleeves, straps and other wearable materials).
This standard addresses the growing market for screen-touch fabrics and provides repeatable, instrumented methods to assess whether a textile reliably activates capacitive displays.
Key Topics and Requirements
- Scope and definition
- Defines screen-touch property as the ability of a fabric to control a capacitive display through touchscreen induction.
- Test principle
- Instrumented testing of specimens using a testing head to perform single-point, multi-point, and sliding (slide) touch tests under standardized conditions.
- Apparatus and test equipment
- Requires a mobile arm, stage, reference screen, cylindrical test bar, and force sensor.
- Test equipment for touch performance must comply with IEC 62908-12-10 and IEC 62908-12-20.
- Position resolution requirement shown in the document: 0.01 mm.
- Conditioning and atmosphere
- Conditioning and testing atmosphere reference: ISO 139 (standard atmospheres for conditioning and testing).
- Test procedures and result metrics
- Blank (control), single-point, multi-point, and slide tests (line and circular slide variants).
- Result expression includes deviation of precision, response ratio (single-point), adjacent touch distance (multi-point), and linearity (sliding tests).
- Reporting and annexes
- Specifies required test report content and informative annexes describing test equipment and extreme environmental conditions used during development.
Applications and Who Uses It
- Manufacturers of smart textiles and touchscreen-capable garments (e.g., gloves, wearable interfaces).
- R&D teams designing conductive yarns, coatings, or integrated textile sensors for touch interaction.
- Textile testing laboratories and quality control departments validating product performance.
- OEMs and procurement professionals specifying acceptance criteria for touchscreen-compatible textile components.
- Certification bodies and standardization stakeholders assessing compliance and performance claims.
