The aging test chamber mainly refers to the thermal oxidative aging test conducted on rubber, plastic products, electrical insulation materials, and other materials; Or conduct ventilation aging tests for electronic components and plasticized products.

The aging test is divided into temperature aging, sunlight irradiation aging, loading aging, and so on. High temperature aging is generally carried out in several levels. For industrial applications, it is usually carried out at 70 degrees Celsius for 4 hours, and at 15 degrees Celsius for one level. There are generally several levels of aging, including 40 degrees Celsius, 55 degrees Celsius, 70 degrees Celsius, and 85 degrees Celsius, and the time is usually 4 hours.

The laboratories that can carry out aging tests mainly include Suzhou Institute of Electrical Science, National Electrical Product Quality Supervision and Inspection Center, Zikai Environmental Reliability and Electromagnetic Compatibility Testing Service Center, Aerospace Environmental Reliability Testing and Inspection Center, Guangzhou Institute of Electronic Product Reliability and Environmental Testing, etc.

Operation process of ventilated aging test chamber:

1. Before the experiment, check whether all parts and control instruments are normal.

2. Turn on the main power switch, set the total test time, the stop time for ventilation, and the number of tests, and turn on the power and gas switch of the aging chamber. The test chamber begins to heat up, and after the aging chamber reaches a constant temperature, the sample is placed inside.

3. After the temperature is constant, open the test chamber door and firmly place the numbered samples on their turntable. It is advisable for the samples not to come into contact with each other; Close the box door, turn on the "rotation" switch, observe the temperature situation, and record the start time of the test after constant temperature.

During the experiment, observe whether the turntable inside the aging box rotates normally through the lighting inside the box.

During the experiment, attention should be paid to observing whether the control instruments are normal and whether the motor is running normally.

After the experiment is completed, remove the sample, turn off the corresponding switch, and cut off the main power supply.

7. After the box has cooled down, do a good job of cleaning the box and keep a record in the ledger.

8. The aging test chamber should have a dedicated person responsible for its use and daily management and maintenance.

9. The aging test chamber should be calibrated according to the prescribed cycle.
