This document specifies a method, using diluted acetic acid, to determine the mass percentage of chitosan fibres, after elimination of non-fibrous matter, in textiles made of mixtures of:

— chitosan fibre

with

— certain other fibres.

This method is applicable to fibre mixtures of chitosan fibre with cellulose fibres (cotton, linen, ramie, viscose, modal, lyocell), protein fibres (wool, cashmere, silk), or synthetic fibres (polyester, polyamide, acrylic).

This document specifies the method and conditions of test for the determination of the breaking force and elongation at break of individual fibres in the conditioned or wet state.

The determination of these fibre properties, when carried out on different kinds of testing equipment, will not generally give identical results. To avoid such differences, this document is restricted to the use of constant-rate-of-extension testing apparatus.

It is applicable to all fibres, including crimped fibres, provided that the length of fibre available enables the gauge length specified in this document to be used.

NOTE For natural fibres (especially wool and cotton) the breaking test most commonly performed is that of bundles of fibres (see ISO 3060 and IWTO 32-82)

This International Standard establishes a classification system for resilient, textile and laminate floor coverings.

The classification is based on practical requirements for areas of use and intensity of use and is linked to the

requirements specified in the relevant International Standard for each type of floor covering.

This International Standard is also intended to provide guidance for manufacturers, specifiers and consumers,

to enable them to choose the appropriate class of floor covering for any given area of use or specific room.

This standard specifies a method for the automatic determination of the deformability of textile fabrics, including continuous-fibre reinforcement materials.

The method is suitable for use with fabrics (e.g. woven or knitted fabrics, non-wovens, non-crimp fabrics, fabrics made of glass rovings or untwisted carbon filament yarns intended for reinforced composite materials). When applying the method to multi-axial non-crimp fabrics, it shall be noted that the evaluation of the fibre orientation and gaps only incorporates the uppermost layer.

The fabrics could have been treated with powder binder.

This method is not applicable to resin impregnated fabrics.

This International Standard specifies a method of determining the dimensional change (shrinkage) of leathers caused by ageing. It is applicable to all leathers.
