Introduction to Ozone Testing and Its Importance
Ozone is a reactive form of oxygen that can attack double bonds in rubber, leading to cracks, surface degradation, and ultimately, failure of materials. This is especially problematic in industries like:

• Automotive (seals, gaskets, hoses)
• Electronics (cable insulation)
• Aerospace (weatherproofing materials)
• Footwear and sporting goods
• Medical tubing and devices

Testing rubber materials in a controlled ozone environment helps manufacturers simulate years of outdoor exposure in just days or weeks, ensuring that their products can endure harsh operating conditions.

Step 1: Sample Preparation
Before running a test, it is critical to prepare the sample according to the standards being followed. This step ensures the results are both valid and comparable.

Guidelines for sample preparation:

• Use standard dimensions, like dumbbell-shaped or ring-shaped specimens.
• Clean the sample with a dry cloth to remove any oil, dust, or contaminants.
• Make sure the rubber or elastomer has not been previously aged or exposed to UV or ozone.
• Use non-reactive clamps or holders to suspend the sample inside the chamber.
• Maintain uniform spacing between samples to allow even ozone exposure.

Correct sample preparation is the foundation of any accurate ozone aging test.

Step 2: Machine Setup and Power On
Once the samples are properly mounted:

• Plug in the ozone chamber and switch it on.
• Allow the system to initialize, which may take a few seconds depending on the model.
• Calibrate the ozone generator if needed. This ensures ozone concentration accuracy.
• Check and refill the distilled water reservoir (if your model supports humidity control).
• Confirm that the temperature sensors and airflow systems are functional.

Pacorr’s digital interface makes this process easy with an intuitive touchscreen display and software-based setup.

Step 3: Set Testing Parameters
Setting the correct parameters is crucial for conducting a reliable ozone test. The following are the most important settings:

• Ozone Concentration: Usually ranges between 25 to 100 pphm (parts per hundred million), depending on the standard.
• Temperature: Commonly set around 40 degrees Celsius for accelerated aging.
• Test Duration: Can vary from 24 hours to 168 hours or more based on product application.
• Relative Humidity: In some cases, it is necessary to maintain a controlled humidity level, which can be adjusted via internal controls.
• Air Flow Rate: Ensures uniform ozone distribution throughout the chamber.

Save these parameters into memory if your model allows multiple user profiles.

Step 4: Start the Ozone Test Cycle
After setting the parameters:

• Press the “Start” button on the screen.
• The chamber will begin to generate and stabilize the ozone level.
• You will observe on-screen updates for real-time ozone levels, temperature, and timer.
• Throughout the test, maintain a record of environmental conditions if manual logging is required.

Avoid opening the door during the test. Doing so can disturb the internal atmosphere and invalidate results. If your system includes a camera or window, use that to inspect the sample during the cycle.

Step 5: Completing the Test and Analyzing Results
Once the test duration is complete:

• The system will auto-stop or notify you.
• Let the chamber stabilize back to ambient conditions before opening.
• Carefully remove the samples and wear gloves to avoid contamination.

Post-test analysis includes:

• Visual Inspection: Look for ozone cracking, discoloration, or brittleness.
• Microscopic Observation: For micro-cracks or deeper surface degradation.
• Dimensional Changes: Check for swelling or shrinkage using calipers.
• Mechanical Properties: Optionally test for tensile strength, elongation, and modulus.

Record all results and compare them against baseline values to determine material resistance.
