The rubber ozone aging test chamber creates a rigorous ozone-rich environment with controlled ozone concentration, temperature and humidity to test the resistance of rubber materials, plastic products and elastomers to ozone-induced aging.
With support for ISO 1431 and ASTM D1149 ozone aging standards, this chamber is widely used in rubber manufacturing, automotive components, cable insulation, seals, hoses, and elastomer research laboratories. It enables manufacturers to identify early-stage cracking, surface degradation, discoloration, and mechanical property changes.Through closed-loop ozone regulation and uniform internal circulation, the LIB industry rubber ozone aging test chamber delivers high repeatability, stable concentration control, and reliable comparative results.
Key Features – Rubber Ozone Aging Test Chamber
Rubber Ozone Cracking Evaluation
The rubber ozone aging test chamber is engineered specifically for rubber and elastomer materials, combining ozone exposure with tensile deformation to reproduce real service aging mechanisms rather than simplified laboratory conditions.
Wide-Range Ozone Concentration
Ozone concentration: 1–1000 PPHM
Real-time ozone gas sensors and automatic compensation logic maintain stable concentration throughout long test cycles, ensuring accurate comparison between materials and batches.
Integrated Static & Dynamic Tensile Aging System
Tensile stretch: 5%–35%
Static fixtures and dynamic reciprocating devices allow rubber specimens to be aged under controlled deformation, enabling realistic evaluation of cracking initiation and growth.
Uniform Ozone Exposure
Airflow rate: 0–60 L/min
A dedicated internal circulation duct and centrifugal fan distribute ozone evenly within the workroom, minimizing concentration deviation between sample positions.
Long-Life Silent Discharge Ozone Generator
The silent discharge ozone generator provides high-purity ozone output with low noise and long operational lifespan, ensuring stable performance during continuous aging tests.
Ozone-Resistant SUS304 Stainless Steel Workroom
The SUS304 stainless steel interior resists ozone corrosion, high humidity, and temperature cycling, maintaining structural integrity and test reliability over extended service life.
Standards-Compliant Testing Platform
Fully designed to meet ISO 1431 and ASTM D1149 ozone aging test standards, supporting both internal quality control and third-party certification requirements.

Engineering Details of Rubber Ozone Aging Test Chamber
Combined Static & Dynamic Sample Holder
The integrated static + dynamic combined sample holder ensures specimens remain evenly exposed to ozone while under controlled tension. Optional rotation further enhances exposure uniformity, improving data consistency across multiple samples.
High-Stability Ozone Generation Module
A silent discharge type ozone generator delivers low-noise, high-purity ozone output with long service life. An ultraviolet ozone detection system provides real-time feedback, while automatic compensation maintains target concentration accuracy.
Intelligent Exhaust & Safety Protection
After test completion, the gas exhaust device rapidly removes residual ozone, reducing turnaround time between test cycles. An activated carbon absorption unit neutralizes waste ozone, ensuring operator safety and environmental compliance.
Advanced Programmable Control Platform
The programmable controller allows precise setting of ozone concentration, temperature, humidity, airflow, tensile mode, and exposure duration. Multi-step test programs can be stored, executed automatically, and logged for traceability and audit purposes.
