— Constant flow method, with two compressions, using a test piece of parallel fibres (see Clause 5);
— Simplified constant flow method, with one compression, using a test piece of fibres distributed "at random" (see Clause 6);
— Constant pressure method, with one compression, using a test piece of fibres distributed "at random" (see Clause 7).

This document specifies a method of test for determining the percentage of medullated wool fibres by means of the projection microscope. The method is applicable to woollen and worsted products, at all stages, from raw materials to yarn.

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.

This Standard specifies methods for the identification of some bast fibres (flax, hemp, ramie) using both light microscopy (LM) and scanning electron microscopy (SEM). This document is also applicable to blends of these bast fibres and products made from them.

This standard specifies a method, by determining the nitrogen content, to calculate the proportion of each component, after the removal of non-fibrous matter, in textiles made of mixtures of - jute with - animal fibres. The animal-fibre component can consist solely of hair or wool, or of any mixtures of the two. This document is not applicable to products in which dyestuffs or finishes contain nitrogen.

This document specifies the determination of the ratio of nitrogen isotopes in cotton fibres that are used for textile production. It applies not only to cotton textiles but also to raw cotton taken from cotton fields.

This document specifies three permeametric methods for the determination of the fineness of flax fibres. — Constant flow method, with two compressions, using a test piece of parallel fibres (see Clause 5); — Simplified constant flow method, with one compression, using a test piece of fibres distributed "at random" (see Clause 6); — Constant pressure method, with one compression, using a test piece of fibres distributed "at random" (see Clause 7).

This International Standard specifies the procedure and the measurement conditions for the
determination of the wool fibre diameter using a projection microscope.
The method is suitable for wool fibres in any form and also for other fibres of reasonably circular crosssection.
(In the case of dyed, bleached or finished fibres, the diameter might be different from that of
fibres not subjected to such treatments. The estimates of fibre diameter obtained at the various stages
of processing one ...view more

ISO 18596:2015 specifies a test method for a staple length of dehaired cashmere by a hand-arranging method. ISO 18596:2015 is also applicable to dehaired camel, dehaired yak, etc.

ISO 1136:2015 specifies a method for the determination of the mean diameter of wool fibres, using an apparatus which passes a current of air through a bundle of fibres. This International Standard is applicable to clean, unmedullated wool fibres dispersed in a uniform, open state. It provides a method particularly suitable for combed slivers. The dichloromethane extractable matter content of the specimen must not exceed 1,0 %. It is applicable to oil-combed slivers after cleaning with an organic...view more
