Describes a method for the evaluation of the maturity of raw cotton fibres, or fibres taken from cotton articles which have not been chemically processed.

This International Standard specifies a method for the evaluation of the maturity of raw cotton fibres, or fibres taken from cotton articles which have not been chemically processed.

It is applicable to test specimens taken at random. AnnexB describes other methods of sampling, based on fibre sorter diagrams, or arranged fibres, which permit slightly more accurate appraisals of fibre maturity.
