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.
