departments and other rubber printed products for quality testing.
Test process:
Specimen in the specified requirements of the elongation, fixed
ends of the specimen on the rotating aluminum fixture, and ozonated
air contact, the length of the specimen direction and the direction
of airflow is basically parallel. Specimen adjustable stroke range
before 0-40mm, the specimen to (20 ~ 25) mm / s speed rotation, so
that the specimen in between a plane perpendicular to the airflow,
each specimen continuously move along the same path, the same
specimen rotating a week of time for (8 ~ 12) min, the scanning
area of the specimen is about 40% of the effective area of the test
chamber.

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%. |

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
