Applications
The Ozone Aging Chamber is used to test the colorfastness and aging properties of materials such as rubber, textiles, and fabrics when exposed to ozone. This instrument consists of an ozone generator, fan, baffle, specimen holder, and specimen chamber. The ozone generator utilizes a high-voltage transformer for grid discharge. The generator is positioned upstream of the low-pressure fan. The ozone generator injects ozone into the test chamber. The specimen holder features separable clamps mounted on a wire slip ring, accommodating specimens of various sizes.

Test Procedures
1.Preparation:Verify the ozone generator, fan, baffles, and sample rack are clean and functional.
2.Sample Loading:Mount specimens and control standard on the rotating rack using stainless steel clamps. Ensure all samples are evenly spaced.
3.Parameter Setting:Input ozone concentration, rotation speed, temperature, and relative humidity via the control panel.
4.Test Initiation:Start the ozone generator and rotation system. Monitor ozone concentration and environmental conditions during the test.
5.Observation:During testing, compare the specimen against the control standard for color change. Repeat cycles as necessary until the target fading or aging criteria are achieved.
6.Completion:Stop the system, remove specimens, and record colorfastness or physical aging results for analysis.
