BS ISO 2648:2020

This standard BS ISO 2648:2020 Wool. Determination of fibre length distribution parameters. Capacitance method is classified in these ICS categories:

• 59.060.10 Natural fibres

This document specifies a method for the determination of fibre length distribution parameters (principally mean length, expressed as Hauteur or Barbe, and the coefficient of variation of the measurement) on slivers and rovings made from combed wool or combed synthetic fibres.

As the fibres of different chemical structure have different di-electric values, the method is not directly applicable to slivers made up of a blend of wool/synthetic fibres.
