WG 2 - TC 124/WG 2

IEC 63203-204-1:2023 is available as IEC 63203-204-1:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 63203-204-1:2023 specifies a household washing durability test method for e-textile products. This document includes testing procedures for e-textile products with electrically conductive components and sensors to collect the data of the user. This document does not cover safety or heat-generation test methods. Products containing components other than those listed in this clause are not covered by this document. This second edition includes the following significant technical changes with respect to the previous edition:
a) Subclause 3.2 on conductive textiles has been deleted.
b) Subclause 3.3 on leisurewear and sportswear has been deleted.
c) Subclause 3.2 on washing procedure has been added.
d) Figure 1 has been updated.
e) The optional measurement of conductive tracks has been added in 4.1 to the checklist before carrying out washing durability test.
f) Additions have been made to the list in Clause 6.

IEC 63203-201-2:2022 specifies the provisions for conductive fabrics and insulation materials used for electronic textiles and measurement methods for their properties.
Conductive fabrics covered by this document are basic materials in electronic textiles and are mainly used as conductive traces, electrodes and the like in clothes-type wearable devices. This document does not cover high-resistance conductive fabrics used for antistatic purposes and heater applications.
Insulating materials handled in this document are materials used for electrical insulation of conductive parts in electronic textiles. They include materials for covering the conductive parts, and general fabrics constituting the basic structure of clothes‑type wearable devices.
This document does not define the required characteristics of the conductive fabric and insulation materials; rather, it specifies measurement methods for general and electrical properties of the conductive fabric and insulation materials.

IEC 63203-201-1:2022 specifies provisions and test methods for measurement of properties of conductive yarns. Conductive yarns covered in this document have conductivity of a level that can be used for transmission of electric signals, supply of electric power and electromagnetic shield. They do not include high-resistance conductive yarn used for anti-static and heating use. Conductive yarns are the basic material in electronic textiles and are mainly used as conductive traces in clothes-type wearable devices, as well as with secondary processing (woven, knitted, embroidered, nonwoven, etc.) to provide conductive fabrics.
This document does not define the required characteristics of the conductive yarn; rather, it specifies the handling and measurement methods for general and electrical properties of conductive yarn.

IEC TR 63203-250-1:2021(E) reviews the use cases of conductive snap fasteners applied as electrical connectors for e-textile products available on the market and provides guidance on future standardization works.

IEC 63203-204-1:2021 specifies a household washing durability test method for leisurewear and sportswear e-textile systems. This document includes testing procedures for leisurewear and sportswear products with electrically conductive components and sensors to collect the data of the user. This document does not cover safety or heat-generation test methods. Products containing other components than those listed in this clause are not covered by this document.

IEC 63203-201-3:2021 specifies a test method for determination of the electrical resistance of conductive fabrics under simulated microclimate within clothing. The microclimate is the climate of the small air layer between the skin and clothing having a specific temperature and humidity. This test method can be applied to conductive fabrics including multilayer assemblies for use in clothing.
