Ozone Test Chamber | Ozone Aging Test Chamber

The OTC-150A Ozone test chamber simulates the oxidative effect of ozone on materials in the natural environment. It generates ozone with a controllable concentration using a silent discharge tube, and combines with a precise temperature and humidity control system to replicate the aging process of materials in an ozone environment. Equipped with static/dynamic stretching functions, it can simulate the stress-bearing state of materials. Meanwhile, it monitors parameters such as ozone concentration, temperature and humidity in real time to ensure stable test conditions.

Widely used in fields including rubber, textiles and cables, it is applied to verify properties like ozone cracking resistance of automotive rubber seals, ozone color fastness of outdoor textiles, and ozone aging resistance of cable sheaths. It provides scientific data for material R&D and quality inspection, helps enterprises control the weather resistance of products, and effectively ensures the stable performance and safe service life of products during long-term use.

Test Procedures:
• Sample Preparation: Cut samples in accordance with standards. Use the LISUN HSCD-860 Portable Spectrophotometer to test the color difference value, the LISUN AGM-500 Gloss Meter to test the gloss value, and the LISUN PULL-500KG Tensile Testing Machine to test the tensile strength. Record the data as the baseline.
• Equipment Inspection: Confirm that the ozone generator, sensors, and fixtures are connected properly. Calibrate the ozone concentration, temperature, and humidity parameters.
• Parameter Setting: Set the ozone concentration (e.g., 50 pphm), temperature (18-28℃), humidity (≤67% RH or 85-95% RH), and test duration. Select the static/dynamic stretching mode.
• Sample Installation: Fix static samples on the holder (with a spacing of ≥15mm); pre-stretch dynamic samples before clamping to ensure they are secured firmly.
• Equipment Startup: Close the chamber door. Start the ozone generator after the temperature and humidity stabilize, and begin timing once the parameters meet the standards within 30 minutes.
• Process Monitoring: Check the operating data regularly. For the dynamic mode, inspect the sample clamping condition and avoid opening the chamber midway.
• Test Conclusion: After the timing is completed, start the exhaust system for 30 minutes. Remove the samples when the ozone concentration drops to ≤0.1 ppm.
• Condition Adjustment: Place the samples in a standard environment (23℃±2℃, 50%±5% RH) for 4 hours.
• Performance Retesting: Use the LISUN HSCD-860 Portable Spectrophotometer, LISUN AGM-500 Gloss Meter, and LISUN PULL-500KG Tensile Testing Machine again to test the color difference value, gloss value, and tensile strength respectively. Track the aging changes and compare with the initial values to evaluate the aging degree.
• Result Evaluation: Calculate the aging indicators by comparing with the initial data, grade the results, generate a report, clean the equipment, and then shut it down.
