Full title and description

St IEC 63203-201-4-2025 — Wearable electronic devices and technologies — Part 201-4: Electronic textile — Test method for determining sheet (laminar) resistance of conductive fabrics after abrasion. This document defines a reproducible Martindale-based abrasion procedure and a means to measure change in sheet resistance of conductive woven, knitted, nonwoven, coated and embroidered textiles intended for wearable electronic applications.

Abstract

This standard specifies a test procedure to measure the sheet resistance of conductive fabrics after abrasion treatment using the Martindale abrasion machine. It is intended to provide manufacturers, test laboratories and R&D teams with a standardized method to evaluate durability of electrical conductivity after mechanical wear, so performance and comparisons between materials and processes can be made. The procedure covers sample preparation, conditioning, Martindale test parameters, post‑abrasion electrical measurement and reporting.

Scope

This part specifies a test procedure to measure the sheet resistance of conductive fabrics after abrasion treatment using the Martindale abrasion machine. It applies to conductive woven and knitted fabrics, conductive nonwovens, coated conductive textiles and fabrics with conductive embroidery (conductive yarns). The document defines Martindale parameters, conditioning, abrasion cycles, electrical measurement methods (sheet resistance) and the format for reporting results and test conditions.

Key topics and requirements

• Definition of sample preparation and conditioning prior to abrasion (standard atmospheres and specimen dimensions).
• Specification of Martindale abrasion test parameters (load, abrasive material, number of cycles) to simulate wear.
• Methods for measuring sheet (laminar) resistance before and after abrasion (measurement setup and electrodes, measurement units and calculation of change in resistance).
• Acceptance/reporting criteria and required test report content (number of specimens, mean and variation, description of failure modes).
• Normative references to related test methods for abrasion (EN/ISO 12947 series) and conditioning (EN/ISO 139 series).

Typical use and users

Used by textile and wearable-electronics manufacturers, materials suppliers, independent testing laboratories, product development and R&D teams, certification bodies and quality assurance departments to assess durability of conductive textiles and to compare material choices or manufacturing processes with respect to retained conductivity after mechanical wear.
