This document specifies three methods for the determination of the number of threads per centimetre in woven fabrics. Any of the three methods can be used, the choice depending on the character of the fabric. However, in case of dispute, method A takes precedence.
—     Method A: Dissection of fabric, suitable for all fabrics. This is the most laborious method but has fewer limitations than the others; in particular, it is the only one that is really suitable for the examination of certain folded structures and other complicated weaves.
—     Method B: Counting glass, suitable for fabrics with more than 50 threads per centimetre.
—     Method C: Traversing thread counter, suitable for all fabrics.
Where the number of threads per centimetre is low, it can be convenient to express the results as the number of threads per decimetre.

1.5  A complete test consists of a washing and drying procedure.
NOTE      Use of different parameters (washing machine type, detergent type and type of tumble dryer) can affect test results for any test using this document.

This document defines the generic names used to designate the different categories of man-made fibres, based on a main polymer, currently manufactured on an industrial scale for textile and other purposes, together with the distinguishing attributes that characterize them. The term “man-made fibres” has been adopted for those fibres obtained by a manufacturing process, as distinct from materials which occur naturally in fibrous form.
This document gives recommendations of rules for the creation of the generic name (see Annex A).
NOTE      These rules have been introduced in the sixth edition of ISO 2076, and thus, they are not applicable to the existing generic names of the previous editions.

This document specifies a method for the determination of tear resistance based on the action of an active force applied to a notched test piece.
The test can be carried out on:
test pieces that have been conditioned in a standard atmosphere; or

The results obtained by this method cannot be compared with those obtained by methods involving constant rate of tear.

This document specifies two methods of evaluating the resistance of rubber- or plastics-coated fabrics to the action of liquids by measurement of selected properties of the materials before and after immersion in selected liquids.
The two methods are as follows:

The vibroscope method is not always applicable to hollow and flat (ribbon-like) fibres.

NOTE The final interpretation and the determination of the compensation values remains the responsibility of the project engineer.
Annex C describes a method to determine comparable measures of extensibility along ideally perpendicular directions of coated fabrics. The comparable measures of extensibility can be used by design engineers to assess the extensibility of a coated fabric by comparison with other coated fabrics. In this way, they can help to interpret results of compensation tests. Moreover, they can be used by material suppliers to measure the consistency of extensibility along perpendicular directions of a coated fabric from batch to batch.

This document specifies quantitative test methods to determine the antibacterial activity of all antibacterial textile products including nonwovens.
This document is applicable to all textile products, including cloth, wadding, thread and material for clothing, bedclothes, home furnishings and miscellaneous goods, regardless of the type of antibacterial agent used (organic, inorganic, natural or man-made) or the method of application (built-in, after-treatment or grafting).
This document covers three inoculation methods for the determination of antibacterial activity:
a) absorption method (an evaluation method in which the test bacterial suspension is inoculated directly onto specimens);
b) transfer method (an evaluation method in which test bacteria are placed on an agar plate and transferred onto specimens);
c) printing method (an evaluation method in which test bacteria are placed on a filter and printed onto specimens).
NOTE            Based on the intended application and on the environment in which the textile product is to be used, and also on the surface properties of the textile properties, the user can select the most suitable inoculation method.
