Full title and description

Textiles — Smart textiles — Test method for sheet resistance of conductive textiles using non-contact type. This international standard specifies a non‑destructive, non‑contact test method for determining the sheet resistance of conductive textile structures (sheet form and multilayer assemblies) using eddy‑current (electromagnetic) measurement in a reflection configuration.

Abstract

The standard defines measurement principles, required apparatus and test conditions to determine sheet resistance of conductive textiles and conductive structures intended for use in or on textiles. It is applicable to sheets such as woven, knitted, nonwoven and coated fabrics and to multilayer constructions containing conductive and insulating layers. The method uses eddy‑current technology (non‑contact probe in reflection mode) to infer sheet resistance without electrical contact to the specimen, making it suitable for screening, production quality control and R&D on smart/electronic textiles.

Scope

This document specifies a test method for the determination of the sheet resistance of conductive textile structures by using eddy‑current technology in a reflection (non‑contact) configuration. It applies to conductive textile materials formed as sheets (woven, knitted, nonwoven, coated fabrics) and to multilayer structures containing both conductive and insulating layers where sheet resistance is a relevant property for electrical performance and design of smart textile systems. The method is intended for laboratory and production environments for characterisation and quality control.

Key topics and requirements

• Measurement principle: induction of eddy currents by an alternating primary electromagnetic field and analysis of the reflected/secondary field to derive sheet resistance (non‑contact, reflection mode).
• Required apparatus: eddy‑current instrument (generator/amplifier/demodulator), calibrated sensor probe for non‑contact measurement, specimen support (insulating), and data processing/software to convert eddy‑current signals to sheet resistance values.
• Specimen types and preparation: applicable to sheet forms (woven, knitted, nonwoven, coated) and multilayer assemblies; guidance on specimen size, positioning and surface conditions to ensure repeatable results.
• Calibration and reference: procedures for calibrating the eddy‑current system and using reference materials or calibration standards to relate instrument response to sheet resistance units.
• Reporting and uncertainty: recommended reporting elements (test conditions, probe geometry, measurement area, averaging) and consideration of measurement uncertainty for comparative and quality control use.
• Non‑destructive advantage: suitable where electrical contact would damage the sample or alter its properties; supports rapid scanning and mapping of sheet resistance across textile surfaces.

These key topics are described in the published ISO text and associated national/adopted versions.

Typical use and users

Typical users include textile testing laboratories, manufacturers of conductive and smart textile products, R&D teams developing e‑textile sensors and interconnects, quality assurance engineers performing production control, and standards bodies referencing measurement methods. The method is used for material characterisation, incoming inspection, process control and product development where sheet resistance is a performance parameter.

Related standards

This ISO standard has been adopted in various regional/national collections (for example as EN ISO 24584:2022 and other national designations). Some national bodies have published corrigenda or national implementation documents referencing ISO 24584:2022. When specifying testing in contracts or regulatory contexts, users commonly cite the ISO document together with any applicable national adoption (EN/ISO or national standard) or implementation notes.

FAQ

Q: What is this standard?

A: ISO 24584:2022 is an international standard that specifies a non‑contact (eddy‑current, reflection mode) test method to determine the sheet resistance of conductive textile structures.

Q: What does it cover?

A: It covers measurement principles, required equipment, specimen preparation, calibration and reporting for sheet resistance testing of sheet‑form conductive textiles and multilayer textile assemblies, using non‑contact eddy‑current instrumentation.

Q: Who typically uses it?

A: Textile test laboratories, smart‑textile manufacturers, R&D groups working on e‑textiles and wearable electronics, and QA/QC teams use this method for characterisation and production control.

Q: Is it current or superseded?
