标准范围

规定了主要用于测定所有羊毛条和粗纱的平均长度和长度变异系数的方法。它不直接适用于由两种或两种以上纤维混合而成的条子。使用称为“机械夹”的辅助机器选择试样。它可用于顶部棉条、精纺牵伸棉条和粗纱，以及半精纺系统的棉条。

Specifies a method for the determination principally of mean length and coefficient of variation of length for all-wool slivers and rovings. It is not directly applicable to slivers made up of a blend of two or more fibres. Selection of test specimen is effected using an auxiliary machine, called "mechanical grip". It may be used on top slivers, on worsted drawing slivers and rovings, and on slivers from the semi-worsted system.
