1   Scope and field of application This International Standard specifies

— three methods for determination of the length of staple fibres by measuring individual fibres;

— different methods of expressing the length distribution from values obtained by measurement of individual fibres.

It applies to all discontinuous textile fibres, except those in which strong inherent crimp would render the procedure inapplicable. It does not apply to fibrous bundles of bast fibres.
