Wool -- Determination of fibre length distribution parameters -- Electronic method
This standard was last reviewed and confirmed* in 2011.
*Therefore this version remains current
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.
