This European Standard describes a test method for the determination of the linear electric resistance of conductive tracks for textile structures or intended for application in\/ to textiles, e.g. yarns, printed or coated tracks, ropes, ribbons and webbing.<\/p>\n
This European Standard is designed for materials showing ohmic behaviour.<\/p>\n
This European Standard is designed for conductive tracks where electrical contact between the measurement electrodes and the conductive track is possible.<\/p>\n
