This part of IEC 63203-201 specifies terms and test methods for measurement of properties of conductive yarns. Conductive yarns covered in this standard 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.
