标准范围

ISO 16549:2004描述了一种使用电容测量设备来确定沿纺织线长度的线密度不均匀性的方法。本方法适用于由天然纤维或人造纤维制成的毛条、条子、粗纱、细纱和连续长丝，短纤维股为4 tex（g/km）至80 ktex（kg/km），连续长丝为1 tex（g/km）至600 tex（g/km）。它不适用于花式纱线或完全或部分由金属等导电材料组成的股线；后者需要一个光学传感器。ISO 16549:2004描述了方差-长度曲线的制备，以及线密度周期性的测定，还涵盖了纱线缺陷的计算，即棉结和粗细部位的计算。

ISO 16549:2004 describes a method, using capacitance measuring equipment, for determining the unevenness of linear density along the length of textile strands.The method is applicable to tops, slivers, rovings, spun yarns and continuous filament yarns, made from either natural or man-made fibres, in the range of 4 tex (g/km) to 80 ktex (kg/km) for staple-fibre strands and 1 tex (g/km) to 600 tex (g/km) for continuous-filament yarns. It is not applicable to fancy yarns or to strands composed fully or partly of conductive materials such as metals; the latter require an optical sensor.ISO 16549:2004 describes the preparation of a variance-length curve, as well as the determination of periodicities of linear density, and covers also the counting of imperfections in the yarn, namely of neps and of thick and thin places.
