ISO 7326 Static Dynamic Ozone Chamber for Hose

Ensure the Durability and Compliance of Your Hose Products Against Environmental Degradation.Ozone concentration in the atmosphere is a primary cause of rubber cracking. By simulating and accelerating ozone aging conditions in a controlled environment, this chamber helps manufacturers, R&D labs, and quality control departments accurately predict the lifespan of industrial, automotive, and hydraulic hoses, ensuring strict compliance with international testing standards.

Fully engineered to meet the stringent requirements of ISO 7326 (Methods 1-4), our chamber bridges the gap between laboratory simulation and harsh operational environments. It forces your hose products to undergo aggressive, real-time static stretching and high-frequency dynamic flexing under precise ozone concentrations—ensuring your products never fail in the field.


Model: OC-250, OC-500, OC-800, OC-010 and more customized models.

Compliant Standards: ISO 7326 | ISO 1431 | ASTM D1149 | JIS K6259 | SAE J2020

Key Technical Highlights of ISO 7326 Static Dynamic Ozone Chamber for Hose

Dual Test Modes: Static & Dynamic Integration

  • Static Tensile Test (Method 1 & 2): Equipped with adjustable mandrels. Hoses are wrapped around the mandrels at specified extensions to test resistance under static stress.

  • Dynamic Bending/Stretching Test (Method 3 & 4): Driven by a high-precision servo motor, the dynamic mechanism continuously flexes, stretches, or rotates the hose samples at preset frequencies and strokes to simulate real-world mechanical movements.

Advanced Ozone Generation & Closed-Loop Control

  • Silent Discharge Technology: Utilizes an advanced ozone generator to provide a stable, continuous ozone supply.

  • UV Absorption Detector: Measuring concentration in real-time, feeding data back to the PLC to maintain fluctuation within safe boundaries.

Precision Environment Control

  • Uniform Airflow: Specially designed air circulation system ensures consistent temperature, humidity, and ozone concentration throughout the entire working room.

Smart Control System & Safety

  • 7-Inch Programmable Touch Screen Controller with multi-Language option

  • Real-time Graphing: Displays real-time curves for temperature, humidity, and ozone concentration.

  • Data Logging: Stores historical test data; supports USB export for easy laboratory report generation.
