Measuring principle: Expose the sample to ozone under specified conditions, and measure the time when the first crack occurs, or measure the exposure time without cracks to evaluate the effect of ozone on rubber or plastic coated fabrics. The HG / T 2716-2008 ozone aging test chamber standard is for the determination of the static ozone cracking resistance of rubber or the coated fabric. Warning: Persons using this ozone aging test chamber standard should be familiar with formal laboratory operating procedures. This standard is not intended to cover all safety issues that may arise due to the use of this standard. It is the user's responsibility to develop appropriate safety and health systems and ensure compliance with national regulations. Main scope of application: This standard specifies the determination method of resistance to ozone cracking of rubber or plastic coated fabrics under static conditions. It is mainly applicable to the determination of the relative ozone cracking resistance of rubber or plastic coated fabrics under static strain when exposed to the air without ozone and ozone. As with all aging tests, the ozone resistance test should be considered as a means of comparing products of the same composition and use, but not an absolute criterion. It is best to limit the meaning of the test, that is, to understand the test only as a means of control when a certain degradation compared to the fabric to obtain ozone cracking resistance better than a given threshold value. Based on this point of view, the results of the test cannot be used to predict the life of the product. Normative references: The clauses in the ozone aging test chamber standard become the clauses of this standard after being quoted by this standard. For dated reference documents, all subsequent amendments (not including errata content) or revisions are not applicable to the standard. However, the research labs that have reached an agreement based on this standard are encouraged to use the latest versions of these documents . For the cited documents without date, the latest version is applicable to this standard.
