How to choose an ozone aging test chamber

The ozone aging test chamber can simulate and intensify ozone conditions in the atmosphere, study the effect of ozone on rubber, rapidly identify and evaluate the anti-ozone aging performance of rubber and the protective efficacy of anti-ozonants, thereby enabling effective anti-aging measures to extend the service life of rubber products.

When selecting an ozone aging test chamber, it is essential to align your choice with your specific needs. Here are some practical tips to guide your purchase:

Environmental Temperature Considerations:

Choose based on your testing requirements. Some products necessitate ozone resistance tests at sub-zero temperatures, while others are evaluated at room temperature (23°C) or elevated temperatures. Identify the typical testing temperature for your applications. Notably, room-temperature testing is common. If your laboratory lacks air conditioning, opt for a chamber with a refrigeration system to prevent inaccurate results due to high ambient temperatures during summer.

Manufacturer Credentials:

Prioritize experienced and reputable manufacturers. A reliable supplier offers not only quality instruments but also crucial post-purchase support, which is equally important.

Chamber Volume:

Opt for the smallest feasible chamber that accommodates your test specimens. Oversized chambers unnecessarily increase costs, as both material expenses and ozone concentration control complexity rise with volume.

Specimen Fixtures:

Static Testing: Stretches specimens to a predefined ratio and monitors cracking in the ozone chamber.

Dynamic Testing: Subjects specimens to mechanical fatigue and ozone-accelerated aging using dynamic fixtures.

Simple Aging: Places specimens in the chamber without mechanical stress.

Select the fixture type matching your testing protocol.

Ozone Concentration Range:

Standard rubber tests typically use 50 pphm or 100 pphm ozone concentrations. However, components for specialized applications (e.g., electrical cables, military products) may require higher concentrations. Ensure the chamber’s adjustable concentration range aligns with your testing needs to enhance precision.

By considering these factors, you can select an ozone aging test chamber that optimally balances functionality, cost, and accuracy for your requirements.
