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 establishes guidelines for the specification of vulcanized rubber based on the properties of individual rubber types. This document helps users of rubber products, who are not rubber experts, to create a specification for the rubber materials they wish to use. It also describes a designation system to enable a line call-cut code to be devised for each specification.

Representative specifications for the following rubber types are given in Annexes B to M: natural rubber (NR), styrene butadiene rubber (SBR), nitrile rubber (NBR), hydrogenated nitrile rubber (HNBR), nitrile rubber mixed with PVC (NBR/PVC), chloroprene rubber (CR), ethylene acrylic rubber (AEM), fluorocarbon rubber (FKM), silicone rubber (VMQ), epichlorohydrin rubber (ECO) and ethylene propylene rubber (EPM and EPDM).

This document specifies, for flexible and rigid cellular polymeric materials, laboratory procedures which are intended to imitate the effects of naturally occurring reactions such as oxidation or hydrolysis by humidity. The physical properties of interest are measured before and after the application of the specified treatments. Test conditions are only given for open cellular latex, both open- and closed-cell polyurethane foams, and closed-cell polyolefin foams. Conditions for other materials will be added as required. The effect of the ageing procedures on any of the physical properties of the material can be examined, but those normally tested are either the elongation and tensile properties, or the compression or indentation hardness properties. These tests do not necessarily correlate either with service behaviour or with ageing by exposure to light. If desired, the ageing conditions contained in this document can be applied to composite structures containing any of the above types of cellular material. This can be helpful in the investigation of possible interactions between cellular materials and other substrates. Composite constructions can be in the form of complete finished products or representative small specimens cut there-from.
