Ozone Test Chamber | Ozone Aging Test Chamber

Ozone test purpose:
Ozone Test Chamber (or called Ozone Aging Chamber and Ozone Aging Test Chamber) is design according to rubber being sensitive characteristic of to ozone, it simulate the environmental to accelerate the rubber aging process by ozone. It compared to different products(test sample) aging result each other according to the same ozone aging test conditions/standards, and get to comparable aging resistance performance.

Test process:
The ozone aging test is expose the test sample at the closed, non-illuminated constant ozone concentration air and constant temperature test box. The sample is tested at predetermined time, to evaluate ozone aging resistance through the sample’s cracks degree or other measured performance change. Ozone aging included static tensile test and dynamic tensile test. The ozone concentration, temperature, humidity, and sample tensile ratio are very important parameters in this aging test.
