CEN/TC 248/SC 2 - Physical properties

ISO 10306:2014 specifies a method for the evaluation of the maturity of loose randomized cotton fibres by measuring the resistance to air flow of a plug of cotton fibres under two prescribed conditions. The method is applicable to cotton taken at random from bales. Laps and slivers or other sources of lint cotton may be tested, however results may differ if fibres are taken from bales.

This standard describes methods for the determination of the mass per unit area using small samples in the standard atmosphere for testing and/or oven-dry. It is applicable to woven and knitted fabrics. It may also be applicable to fabrics produced by other techniques.

This standard specifies a method for determination of length and width of textile fabrics that are in the state of relaxation obtained by being free from applied tension in the standard atmosphere for textiles. The test is applicable to textile fabrics of full width, folded vertical down the middle, or in tubularform, but no longer than 100m. This standard does not specify a method to determine or describe construction defects or other defects.

Describes a method for the determination of the thickness of textiles and textile products under specified pressure. Not applicable to textile floor coverings, nonwovens, geotextiles and coated fabrics. replaces the first edition.

Cancels and replaces the first edition (1972). Specifies a method for the determination of the linear density of all types of yarn in package form. Includes seven optional procedures based on different methods of conditioning and preparation. This method is applicable to single yarns; folded yarns; cabled yarns. Not applicable to yarns which stretch more than 0,5 % when the tension, in centinewtons, per unit linear density of yarn, in tex, increases from 0,5 to 1,0. Not applicable to yarns having a linear density greater than 2 000 tex.

Describes a method for measuring the permeability of fabrics to air and is applicable to most types of fabrics, including industrial fabrics for technical purposes, nonwovens and made-up textile articles that are permeable to air.

This standard specifies methods for determination of number of threads per unit length of woven fabrics.

Specifies a gravimetric method and a vibroscope method for the determination of the linear density of textile fibres applicable to bundles of fibres and individual fibres. The procedures can be applied only to fibres which can be kept straight and, in case of bundles, parallel, during test preparation. These methods are properly applicable when the fibres are readily free of crimp. They are not applicable to tapered fibres.

Creases in textile fabrics diminish at varying rates on the removal of the creasing forces. The magnitude of the crease recovery angle is an indication of the ability of a fabric to recover from accidental creasing. The results obtained by this method for textile fabrics of very different kinds cannot be compared directly.

Describes 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 test is restricted to the use of constant-rate-of-extension testing apparatus. Applicable to all types of fibres.

ISO 2061:2010 specifies a method for the determination of the direction of twist in yarns, the amount of twist, in terms of turns per unit length, and the change in length on untwisting, by the direct counting method
ISO 2061:2010 is applicable to
single yarns (spun and filament),
plied yarns, and
cabled yarns.
Separate procedures are given for each type of yarn. The method is designed primarily for yarns in packages, but, with special precautions, the procedures can be used for yarns taken from fabrics. It is not suitable for the determination of twist in a monofilament.
ISO 2061:2010 covers the determination of twist in plied and cabled yarns as follows:
in plied yarns: the final twist of the plied yarns and the original twist of the single yarn before plying;
in cabled yarns:
the final cabling twist of the yarn;
the original twist of the plied yarn after plying, but prior to the last stage of processing;
the twist of the single yarn before plying.

The methods of measurement specified apply to e.g. fabrics, films, coatings, foams and leather, including multilayer assemblies, for use in clothing, quilts, sleeping bags, upholstery and similar textile or textile-like products. Application is restricted to a maximum thermal resistance and water-vapour resistance which depend on the dimensions and construction of the apparatus used (e.g. 2 m^2 K/W and 700 m^2 Pa/W, respectively), for the minimum specifications of the equipment referred to.

Specifies a method for the evaluation of the maturity of loose randomized cotton fibres by measuring the resistance to air flow of a plug of cotton fibres under two prescribed conditions. The method is applicable to cotton taken at random from bales. Laps and slivers or other sources of lint cotton may be tested, however results may differ if fibres are taken from bales.
