This document specifies a procedure to determine the maximum force and elongation at maximum force of textiles woven fabrics using a grab method in the biaxial testing machine. The method is mainly applicable to woven textile fabrics, including fabrics which exhibit stretch characteristics imparted by the presence of an elastomeric fibre, mechanical, or chemical treatment. It can be applicable to fabrics produced by other techniques. It is not applicable to geotextiles[4], nonwovens[3], coated fabrics[5], textile-glass woven fabrics[2], and fabrics made from carbon fibres or polyolefin tape yarns. The method is restricted to the use of constant rate of extension (CRE) testing machines to the same axis.

This document specifies a method for the automatic determination of the deformability of textile fabrics, including continuous-fibre reinforcement textiles. This method is not applicable to resin impregnated fabrics. The method is suitable for use with fabrics such as woven or knitted fabrics, nonwovens, 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, the evaluation of the fibre orientation and gaps only incorporates the uppermost layer. The method can be used for fabrics treated with powder binder.

This document describes a hydraulic method for the determination of bursting strength and bursting distension of textile fabrics. In this document, a hydraulic pressure is applied using a constant rate of pumping device. NOTE ISO 13938-2 describes a method using pneumatic pressure. The method is applicable to knitted, woven, nonwoven and laminated fabrics. It can be suitable for fabrics produced by other techniques. The test is suitable for test specimens in the conditioned or wet state. From the available data, there appears to be no significant difference in the bursting strength results achieved using hydraulic or pneumatic burst testers, for pressures up to 800 kPa. This pressure range covers the majority of performance levels expected of general apparel. For speciality textiles requiring high bursting pressures, the hydraulic apparatus is more suitable.

ISO/TR 23697:2011 can be applied to textiles and textile products and is concerned only with test methods which operate in a continuous scale to yield a single numerical figure as the test result. However, this single figure can be the outcome of a calculation from a set of measurements. The distribution of test results is required to be unimodal and is assumed to be normal. With non-Gaussian distributions, other evaluation procedures will be necessary. It does not cover methods which yield discrete values, "pass/fail" (go/no go) type results, (accept/reject) tests or where a ranking scheme is in operation.

Threads are removed from a strip of fabric of known length, straightened by a tension which is varied according to the nature and linear density of the yarn, and measured in the straightened state. The difference between the straightened length of the thread and the distance between the ends while in fabric is expressed as a percentage of the latter.

A length of yarn is removed from the fabric and, while under tension, is secured in two clamps which are at a known distance apart. One of these clamps is then rotated until all twist is removed from the length of yarn.

Three methods of determining the number of threads per centimetre are included, any of which may be used, the choice depending on the character of the fabric. The principles are as follows: Method A: A section of fabric of dimension specified is dissected and the number of threads counted. The treads that are to be counted are preferably short, 1 or 2 cm being suitable. Method B: the number of threads visible within the aperture of a defined counting glass is determined. Method C: the number of threads per centimetre of the fabric is determined with the aid of a traversing thread counter.

For some fabrics, mass per unit length and mass per unit area are related simply by the width of the fabric, but for other fabrics variations in structure may introduce an important distinction between mass per unit length and mass per unit area. The methods are applicable to woven fabrics (including those of "stretch" type) made up full width or folded down the middle, and apply to the determination of the fabric mass of complete pieces as well as of sample length.
