ISO/TC 45/SC 4/WG 13 - Coated fabrics

This document specifies two methods for measuring gas transmission through rubber- or plastics-coated fabrics, a property known as permeability.

This document specifies a procedure for determining the lowest temperature at which rubber- or plastics-coated fabrics will not exhibit fractures or coating cracks when subjected to specific impact conditions. Rubber-or plastics-coated fabrics are used in many applications involving low-temperature flexing with or without impact. Data obtained by this method can be used to predict the behaviour of these coated fabrics at low temperatures only in the applications in which the conditions of deformation are similar to those specified in the method.

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 test pieces that have undergone pre-treatment, e.g. water immersion. The results obtained by this method cannot be compared with those obtained by methods involving constant rate of tear.

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 specifies a test method which is intended to determine the fogging characteristics of rubber- or plastics-coated fabrics that are used as trim materials in the interior of motor vehicles. The method can also apply to fluid, pasty, powdered or solid raw materials which are the basis for such trim materials or from which the materials are manufactured. The method can also apply to other materials and finished products. The procedure is applicable to the measurement of fog condensate on glass surfaces within the limits of the test conditions. This test cannot measure accurately those cases in which: — the surface tension of the condensate is low, resulting in early coalescing into a thin transparent film; — the condensate is present in such a large quantity that the droplets coalesce and form a heavy oily/clear film (this heavy film gives false readings). In such cases, the gravimetric method is preferred.

This document specifies a method for the determination of the bursting strength of rubber - or plastics - coated fabrics, using one of two types of diaphragm bursting tester, designated type A and B, both operated by hydraulic pressure. The type A test machine is applicable to materials having bursting strengths ranging from 350 kPa to 5 500 kPa and the type B test machine is applicable to materials of bursting strengths ranging from 70 kPa to 1 400 kPa.

This document describes four methods of assessing the resistance of coated fabrics to deterioration by accelerated ageing.

This document specifies a test method for determining the flex resistance of rubber- or plastics‑coated fabrics in the folded condition. The test method is applicable only to products which can be clamped in the test apparatus used and to products with which the fold made in the test specimen can be caused to move back and forth along the specimen during the test. The appearance of the test specimen, after completion of either the flex number (see 3.1) or a specified number of flex cycles, is taken as a measure of the flex resistance in the folded condition.

ISO 2411:2017 specifies a method of determining the coating adhesion strength of coated fabrics.

ISO 4675:2017 specifies a method for determining the ability of fabrics coated with rubber or plastics to resist the effect of low temperature when subjected to bending at specified temperatures after definite periods of exposure. This method is applicable to material with a thickness within the range 0,1 mm to 2,2 mm. For materials of greater thickness than this, modifications to the standard equipment apply (see 9.2, third paragraph). Because fabrics coated with rubber or plastics are used in different applications requiring low temperature flexing, no general relationship between this test and service performance can be given or implied.

ISO 1421:2016 specifies two methods for the determination of the tensile strength of fabrics coated with rubber or plastics. - Method 1 ? the strip test method, which is a method for the determination of tensile strength and elongation at break. - Method 2 ? the grab test method, which is a method for the determination of tensile strength only. The methods apply to test pieces in equilibrium with specific standard atmospheres for testing and to wet test pieces. Both methods require the use of a constant rate of extension (CRE) tensile-testing machine.

ISO 1420:2016 specifies two methods for the determination of the resistance of rubber- or plastics-coated fabrics to water penetration (hydrostatic resistance) when subjected to a specific hydrostatic pressure over a fixed period of time. Method A specifies the procedure for a low and high hydrostatic pressure and Method B for a low hydrostatic pressure.

ISO 5981:2007 specifies two methods of evaluating the resistance to combined shear flexing and rubbing of rubber- or plastics-coated fabrics. Rubbing is either forced by application of a pressure foot (method A), or is caused by simple contact between the faces of the test pieces (method B). Method B (without application of the pressure foot) is preferred in all cases where the foot would damage the test piece through an abrasive effect where this is not required, e.g. materials with sticky surfaces, light coatings such as polyurethanes on rough surfaces. The test may be carried out on products as delivered or after pre-treatments such as wetting or accelerated ageing. NOTE The results obtained using method A and method B cannot be compared as there is no correlation between the two methods.

ISO 7617-2:2003 specifies requirements for coated fabrics for upholstered furniture, manufactured by applying to one side of a woven cloth a substantially continuous coating of a suitably plasticized polymer of vinyl chloride, or a copolymer the major constituent of which is vinyl chloride. Such coatings are known as poly(vinyl chloride) (PVC) coatings. The present specification covers two grades (A and B) of PVC-coated woven fabric.

This part of ISO 7617 specifies technical requirements for coated fabrics for upholstered furniture for interior use, obtained by applying to one side of a weft-knitted base cloth a substantially continuous coating of a suitably plasticized polymer of vinyl chloride, or a copolymer the major constituent of which is vinyl chloride.

Specifies a method for checking the coatings on coated fabrics. Not suitable for coatings obtained from aqueous dispersions of PVC.

Only suitable when the material to be tested is substantially uniform in thickness and flat or sufficiently flexible to remain flat in case of slight compression. Particularly suitable for materials having a very thin rubber layer which are difficult to test by stripping or peeling methods. However, it should be noted that the results obtained by this method will not necessarily correlate with those obtained by a stripping test. A figure shows the prepartion of test assembly.
