1.7. Uses

The content of ozone in the atmosphere is very little but the main factor of rubber cracking, this product simulates and strengthens the ozone conditions in the atmosphere, to study the law of ozone action on rubber, to quickly identify and evaluate the performance of rubber anti-ozone-aging and anti-ozone-agent protection effectiveness of the method. Reference standards: GB/T7762-2014 static tensile test method for ozone cracking resistance of vulcanized rubber or thermoplastic rubber, GB/T2951.21-2008 general test method for cable insulation and sheathing materials, GB/T 11206-2009 surface cracking method for rubber aging test, and other test methods specified in relevant standards.

1.8. Principles

and Methods

The test method can be divided into “static” and “dynamic” according to the test method and standards, static means that the sample is stretched well or the product directly into the test chamber to do the test, dynamic is placed in the test chamber on the fixture, stretching the float for the tested sample itself about 5% -45%.

Requirements (only

for Dynamic Testing)

At both ends of the specimen to be tested, the specimen should be tested in a direction essentially parallel to the direction of the airflow when in contact with the ozonated air

The fixture should be made of a material that does not readily decompose ozone (e.g., aluminum).

The specimen is rotated at a speed of (20^-25) mm/s in a plane of vertical dry airflow, with each specimen continuously and simultaneously maintaining a fixed rate of pull-up.

The same specimen rotation time of one week is (8^-12) min. The scanning area of the specimen is at least 40% of the effective area of the test chamber.

Specimen preparation should be in accordance with the provisions of GB/T 9865.1. Specimens should preferably be cut from the newly molded test piece, if necessary, can be cut from the finished product. Specimens should be at least 3 specimens for each test condition. Long standard specimen width of not less than 10mm, thickness 2.Omm Shi 0.2mm, the length of the specimen between the ends of the jig before stretching is not less than 40mm.
