Simulate Ozone Exposure to Validate Rubber and Elastomer Durability

Ozone is one of the most damaging environmental factors for rubber, elastomers, and other polymer-based products, attacking materials under tensile stress and causing surface cracking that can progressively weaken and destroy them — even at very low atmospheric concentrations.

LIB ozone testing solutions help manufacturers evaluate how rubber compounds, seals, gaskets, cables, and other elastomeric products will perform under ozone exposure, from automotive seals and hoses to O-rings and industrial rubber components, reproducing precise ozone concentration, temperature, and mechanical stress conditions to identify cracking risks before products reach the market.

With accurate ozone generation and monitoring, customizable test parameters, and complete after-sales support, LIB helps manufacturers worldwide improve product durability and meet international ozone resistance standards.

Ozone Testing Methods

Different rubber and elastomer products require different ozone exposure conditions depending on their application, material composition, and industry standards.

LIB provides environmental simulation solutions for the following ozone-related tests:

Static Ozone Test

Static ozone testing exposes stretched or statically strained rubber specimens to a controlled ozone concentration for a fixed period, evaluating surface crack resistance under constant deformation.

Common standards:

· ISO 1431-1

· ASTM D1149

Dynamic Ozone Test

Dynamic ozone testing exposes specimens to ozone while undergoing repeated flexing or cyclic deformation, simulating rubber components that experience continuous movement during service, such as seals and hoses.

Common standards:

· ISO 1431-1

· ASTM D1149

Ozone Aging Test

Ozone aging testing combines extended ozone exposure with elevated temperature to accelerate material degradation and estimate long-term product lifetime under ozone attack.

Common standards:

· ISO 1431-1

· ASTM D1149

Combined Ozone and Temperature Test

Ozone resistance can vary significantly with temperature, so many test programs combine ozone exposure with controlled temperature conditions to better simulate real operating environments.

Applicable standards:

· ISO 1431-1

· ASTM D1149

Ozone Testing Equipment Selection Guide

Choosing the correct ozone test chamber depends on: Required ozone concentration range, temperature requirements, specimen mounting method (static or dynamic), sample size, test standard, industry application, and test duration.

LIB provides different ozone simulation chambers to meet various testing requirements.

Key Technical Specifications

Frequently Asked Questions

What equipment is used for ozone testing? 

Ozone testing is usually performed using an ozone test chamber, also called an ozone aging chamber or ozone resistance test chamber. LIB provides static, dynamic, and combined ozone-temperature chambers for different testing requirements.

What is the difference between static and dynamic ozone testing? 

Static ozone testing exposes specimens held under constant strain to ozone, evaluating crack resistance under fixed deformation. Dynamic ozone testing exposes specimens to ozone while they undergo repeated flexing, better simulating components that move continuously during service, such as hoses and seals.

Why does rubber crack when exposed to ozone? 

Ozone reacts with the double bonds present in many rubber polymer chains, particularly in materials under tensile stress. This reaction breaks down the polymer structure at the surface, forming small cracks that grow perpendicular to the direction of stress over time.

What industries need ozone testing? 

Ozone testing is widely used in:

· Automotive

· Cable and wire

· Rubber and elastomer manufacturing

· Industrial sealing components

· Aerospace

· Construction
