本文件规定了在静态条件下测定涂有橡胶或塑料的织物耐臭氧开裂性的方法。 该试验旨在确定在没有阳光直射的情况下，在静态应变下暴露于含有臭氧的空气中时，涂有橡胶或塑料的织物的相对抗裂性。 与所有老化试验一样，应将其视为比较相同成分和相同用途物品的一种方法，但不是绝对标准。当织物达到高于给定阈值（与特定类型的降解相比）的阻力时，最好通过将其视为一种控制手段来限制试验的显著性。 考虑到这些备注，试验时获得的结果不能作为产品寿命的预测。

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.
