Certificate & Standards
CE certification
Standards: JISK 6259, ASTM 1149 , ISO 1431, GB/T 7762-2022, GB/T 11206, GB/T 13642, GB/T 2951
Ozone test chamber is an environmental chamber used to test the ozone aging resistance of rubber products. It utilizes the internationally accepted non-dispersive ultraviolet standard (dual-speed ultraviolet) to measure the ozone concentration, simulating and intensifying ozone conditions in the atmosphere to study the effects of ozone on materials like rubber. This enables rapid identification and evaluation of the anti-ozone aging properties of rubber materials and the protective efficacy of anti-ozone agents. Alternatively, it necessitates the adoption of effective anti-aging measures to extend the service life of rubber products.
- In the automotive manufacturing industry, ozone test chambers are used to test the durability of automotive components.
- In the construction materials manufacturing industry, ozone test chambers are used to evaluate the weather resistance and durability of building materials (such as sealants, insulation materials).
- Components and enclosures in the electronics industry often need to withstand various environmental conditions, including ozone, ultraviolet light, and high temperatures.
- In the plastic & rubber manufacturing industry, ozone test chambers are used to simulate the aging process of materials in outdoor environments to assess their performance and lifespan.
- In the packaging materials manufacturing industry, packaging materials require a certain level of weather resistance and stability to protect the products within.
- Ozone test chambers are crucial testing equipment in research institutions, providing researchers with reliable means to study material aging mechanisms, performance changes, and lifespan prediction.
- Ozone test chamber is able to perform static endurance test, exposing the samples to sealed air with a certain concentration of ozone and constant temperature.
- Ozone test chamber is also able to perform testing under static strain or continuous dynamic strain, or after interrupting dynamic tensile and static strain. To test, expose the products in a closed, sunlight-free and temperature-controlled environmental test chamber. And then observe the cracks on the test products’ surface, or the changes of other properties to evaluate the ozone resistance of vulcanized rubber.
- Ozone test chamber is equipped with an internal circulation air duct. The ozone concentration, temperature, and humidity are controlled via computer. These ensure uniform airflow parallel to the surface of the specimens, in compliance with international standards.
- Computerized ozone concentration, temperature, and humidity controller offers high integration, LED display, high temperature and humidity resolution, and good reliability.

Beier Labs is the only manufacturer in China capable of integrating both dynamic and static tensile specimen racks into a single ozone aging test chamber! We achieve this by increasing the equipment size and incorporating independent space, thereby meeting customers' compatibility needs.
I'm unsure what configuration of ozone test chamber my company's product needs. Could you explain the differences?
Requirements for ozone test chambers vary significantly across different industries. Below are the main distinctions in ozone chamber needs for the textile industry (e.g., Luolai), the rubber industry, and the electronics industry (e.g., Gree):
- Textile Industry: Typically requires low ozone concentration, high humidity, a narrow temperature range, and specimen racks suitable for flat samples. Ozone aging tests for textiles usually need lower ozone concentrations (e.g., 10 ppm ~ 50 ppm) but demand more precise humidity control, often requiring relative humidity between 60% and 80%. Humidity significantly impacts the aging speed and manner of textiles, with high humidity accelerating hydrolysis and oxidation of fibers.
- Rubber Industry: Requires high ozone concentration, low humidity, a wide temperature range, and specimen racks suitable for tensile or hanging samples. Ozone resistance tests for rubber materials typically demand higher ozone concentrations (e.g., 50 ppm ~ 1000 ppm) because rubber's ozone resistance is relatively stronger than textiles, necessitating higher concentrations to accelerate the aging process. Rubber samples are often strip-shaped or block-shaped, requiring specimen racks designed for stretching or hanging to simulate stress conditions during actual use.
- Electronics Industry: Requires moderate ozone concentration, moderate humidity, a narrow temperature range, and specimen racks suitable for fixed and powered testing. Ozone resistance test concentrations for electronic components are usually between 20 ppm and 100 ppm. Outer casing materials of electronic components (e.g., plastics, rubber) need to be tested at lower concentrations to evaluate their durability in long-term, low-concentration ozone environments. Humidity requirements for electronic component testing are generally stricter, typically between 40% and 60%, to simulate humidity conditions in actual use environments. High humidity might lead to a decrease in the insulation performance of electronic components. Electronic component samples are typically small parts or complete devices, requiring specimen racks designed for fixed and powered testing to ensure the normal operation of components during the test.
