ISO 1431-1 Dynamic Rubber Ozone Test Chamber

Name: ISO 1431-1 Dynamic Rubber Ozone Test Chamber
Brand: Xi'an LIB Environmental Simulation Industry

Dynamic Ozone Exposure Testing Equipment for Rubber Crack Resistance

The LIB industry ISO 1431-1 Dynamic Rubber Ozone Test Chamber evaluates the ozone resistance and crack behavior of rubber and elastomer materials under controlled ozone exposure, temperature, and tensile deformation.

Unlike conventional ozone aging chambers that primarily provide static ozone exposure, this system integrates a static and dynamic combined sample holder with controlled tensile stretching and sample movement. It is suitable for dynamic ozone cracking evaluation of rubber products, seals, hoses, gaskets, polymer components, and other ozone-sensitive materials.

With an adjustable ozone concentration of 1–1000 PPHM, temperature control from 0°C to +100°C, and 5%–35% tensile stretch, the chamber provides a controlled environment for laboratory research, material development, quality control, and accelerated durability testing.

Applicable Standards: ISO 1431-1, ASTM D1149

Test Type: Static & Dynamic Ozone Exposure

Warranty & Service: 3-Year Warranty · Lifetime Service · English-Speaking Support Team · 4 Global Service Centers · 29 Authorized Agent

ISO 1431-1 Dynamic Rubber Ozone Testing | Ozone Cracking Resistance Test

Key Features of ISO 1431-1 Dynamic Rubber Ozone Test Chamber

Dynamic Tensile Strain for Ozone Crack Evaluation

The chamber is equipped with a static + dynamic combined sample holder for applying controlled tensile deformation to rubber specimens during ozone exposure. The adjustable tensile stretch range of 5%–35% enables laboratories to evaluate ozone-induced cracking under different deformation conditions, with sample holder rotation adjustable from 0–10 r/min for controlled specimen movement.

Wide Ozone Concentration Control

The system provides an ozone concentration range of 1–1000 PPHM. A silent discharge ozone generator produces stable, repeatable ozone conditions, while an integrated ozone gas sensor continuously monitors and regulates the chamber atmosphere according to the selected test parameters.

Controlled Temperature Environment

The chamber maintains temperatures from 0°C to +100°C, with a temperature fluctuation of ±0.5°C and deviation of ±2.0°C — stable enough for repeatable environmental conditions throughout extended ozone exposure tests.

Static and Dynamic Testing in One Chamber

The combined sample holder supports both fixed and changing tensile strain, making the system suitable for comparative evaluation of rubber cracking behavior under different deformation conditions — without needing separate equipment.

Automated Control and Data Connection

A programmable color LCD touch-screen controller centralizes control of temperature, ozone concentration, sample movement, and test sequences. Ethernet connection and PC Link enable convenient test monitoring and data management.

Static vs. Dynamic Ozone Testing

Test Feature	Static Ozone Testing	Dynamic Ozone Testing
Ozone Exposure	✓	✓
Controlled Temperature	✓	✓
Fixed Tensile Strain	✓	—
Changing / Cyclic Tensile Strain	—	✓
Static + Dynamic Fixture	Optional	✓
Simulation of Repeated Deformation	Limited	✓
Suited to Component Durability Evaluation	✓	✓

Why does dynamic testing matter? Rubber components such as seals, hoses, gaskets, and flexible connectors often experience repeated deformation during service. Dynamic ozone testing combines chemical exposure with mechanical deformation to provide a more demanding, realistic evaluation of ozone-related cracking resistance.

Frequently Asked Questions on ISO 1431-1 Dynamic Rubber Ozone Test Chamber

What is a dynamic ozone test for rubber?

A dynamic ozone test evaluates the resistance of rubber to ozone-induced cracking while the specimen is subjected to controlled tensile deformation or movement — rather than remaining under fixed strain.

What standard is used for dynamic ozone testing?

ISO 1431-1 covers resistance of vulcanized or thermoplastic rubber to ozone cracking under static and dynamic tensile strain. ASTM D1149 is also commonly used for evaluating rubber deterioration and cracking in a controlled ozone environment.

Can the chamber perform both static and dynamic ozone testing?

Yes. The OC series uses a static + dynamic combined sample holder, allowing the system to be configured for different specimen deformation conditions without separate equipment.

Can LIB industry customize the ozone test chamber?

Yes. Chamber volume, specimen fixtures, ozone control, mechanical deformation systems, and control functions can all be customized according to the required test method and application.
