This International Standard specifies a method for the determination of twist in yarns made from textile glass, carbon or aramid filaments.
The method applies to single yarns (one twist) and to folded or cabled yarns (two or more twists). For folded and cabled yarns, the method is generally applied only to the final twist step.
This International Standard is applicable to package-wound yarns. If the measurement is carried out on yarns taken from a beam (or warp) or from a fabric, the result is of an indicative nature only.
The method is not applicable to products made from staple fibres.
