This document specifies a method for the determination of the resistance of fabrics coated with rubber or plastics to ozone cracking under static conditions.

The test is designed to determine the relative resistance to cracking of fabric coated with rubber or plastics when exposed under static strain to air containing ozone in the absence of direct sunlight.

Like all ageing tests, it should be considered as a means of comparing articles of the same composition and destined for the same application, but not as an absolute criterion. It is preferable to limit the significance of the test by considering it only as a means of control when a fabric attains a resistance superior to a threshold given in comparison with a certain type of degradation.

Taking these remarks into account, the results obtained at the time of test cannot be taken as a prediction of the length of life of the product.

This document describes a method for the determination of tear resistance based on the action of an active force applied to a notched test piece.

The test may be carried out on:

— test pieces that have been conditioned in a standard atmosphere, or

— test pieces that have undergone pre-treatment, e.g. water immersion.

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

This part of ISO 5470 details two separate methods for determining the resistance of a material to wet and dry abrasion. It is applicable to the coated surface or surfaces of coated fabrics. If the abrasion behaviour of the uncoated surface of a coated fabric is to be determined, use the methods for uncoated textiles described in the various parts of ISO 12947.

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:

— Method A; total immersion with liquid,

— Method B; one surface side immersion with liquid.
