Accelerated UV chamber Product construction:
- We use corrosion-resistant metal materials to build the chamber structure. It includes 8 fluorescent UV lamps, a water tray, a test sample holder, a temperature and time control system and an indicator.
- The test sample and its bracket form the box’s inner wall. And their backs are exposed to the cooling air at room temperature due to the temperature difference between the test sample and the air inside the box. The condensation stage on the surface of the test sample produces stable condensation conditions. And the test box should produce natural air convection by the bottom through the box’s outer wall and the test sample’s channel.
- The low water tray of the heating box generates the water steam. The water depth is not more than 25 mm, and there is an automatic controller for the water supply. And the water tray should be cleaned regularly to prevent water scale formation.
- The sensor on the black aluminum plate (black plate) is measured, and the black plate should be placed in the center area of the exposure test and the measuring range of the thermometer is 30～80℃, and the tolerance is ±1℃. Light and condensation phase control should be carried out separately, with the condensation phase by the heating water temperature control.
- We should place the uv weathering chamber in the test room with a temperature of 15～35℃, 300mm away from the wall, and should prevent the influence of other heat sources. The air in the test room should not be strongly circulated not to affect the light and condensation conditions.
UV light aging test Test conditions：
To ensure proper testing conditions and maintenance of the test frame, follow these steps:
Set Up The Test Frame And Test Sample.
Set up the test frame in a suitable location, ensuring stability and proper access to the fluorescent lamp and the test chamber. Attach the test sample securely to the test frame, ensuring it faces the fluorescent lamp directly. Make sure to put the sample correctly for accurate testing. If the test sample does not completely fill the sample frame, fill the remaining space with a blackboard or any other suitable material. This will help keep the test chamber closed and minimize external interference. Securely attach or position the blackboard to fill the empty space within the sample frame.
Set The Desired Test Temperature.
You can choose from three temperature options: 50°C, 60°C (recommended priority), or 70°C. For the condensation stage, a temperature of 50°C is suggested. Ensure the temperature tolerance uniformity is maintained within ±3°C during the test. This will help ensure consistent and accurate results.
Select The Desired Cycle For The Light And Condensation Stages.
You can choose between 4 hours of light followed by 4 hours of condensation or 8 hours of light followed by 4 hours of condensation.
Monitor the operating hours of the fluorescent lamps.
When a row of lamps reaches 400 to 450 operating hours, it’s time to replace that row. This helps maintain consistent lighting conditions throughout the test.
Precautions of UV Aging Test Chamber:
- Note the operating hours of the fluorescent lamps. After reaching 400 to 450 operating hours, it is time to replace each row of lamps. And the other lamps follow the lamp cycle and replacement mode to compensate for the loss caused by lamp aging. This mode of operation ensures that the service life of each lamp is 1600 to 1800H.
- During lamp replacement, dry and clean the water tray to prevent the formation of scale. Remove any water, debris, or scale that may have accumulated. This will ensure optimal performance and longevity of the test setup.
- Install the new fluorescent lamps into their respective positions, following the recommended lamp cycle and replacement mode to compensate for lamp aging. This will help maintain the service life of each lamp between 1600 and 1800 hours.
- Double-check all connections, verify the cleanliness of the water tray, and ensure the test frame is ready for operation.
Test Samples and Performance Evaluation (UV Aging Test Chamber)：
- Assessment of appearance: Primarily evaluates the appearance of paint, plastic and rubber. It can also evaluate other items as necessary. Other items that can be checked are mainly gloss, color change, chalking, spotting, blistering, cracking and dimensional stability. Should try to use the instrument for quantitative project testing, such as gloss, color, and difference meter.
- Assessment of mechanical and other properties: general rubber materials for tensile strength, elongation, hardness measurement, plastic measurement of impact strength, elongation at break, tensile strength, bending strength, such as necessary to specify other performance test items.

FAQ
What is the difference between UV aging tester and Xenon lamp aging tester?
The UV aging chamber simulates sunlight or artificial light source, mainly reflecting the product’s ability to resist ultraviolet rays. Mainly for non-metallic materials products, UV aging chamber is the use of eight rated power of 40W UV fluorescent lamps as a light source.
The xenon lamp aging chamber uses a xenon arc lamp that can simulate the full sunlight spectrum to reproduce the destructive light waves that exist in different environments. Compared with UV aging chambers, it also simulates sunlight, but embodies more of the word “full sunlight” because it can produce UV, visible light and infrared light. In a word, xenon lamp aging chamber is to simulate sunlight, while the UV aging chamber is more imitation of the sun’s destructive effect.
What is the difference between UV aging chamber testing and nature?
UV aging chambers simulate UV radiation from sunlight and perform accelerated aging tests on materials to predict their durability in the natural environment. Compared with the natural environment, the test conditions in a UV aging tester can be controlled, and the aging of materials under different UV radiation intensities can be obtained in a shorter period of time, so as to assess the performance of materials more quickly and accurately. However, the test results of the UV aging tester do not fully represent the performance of the material in the natural environment. The intensity of UV radiation, temperature, humidity and other factors in the natural environment will have an impact on the ageing of the material and these factors may not be fully simulated in the UV weathering tester. Therefore, UV aging tester test results should be used as a reference rather than an absolute evaluation standard.
UV ageing test 1 hour How many days is equivalent to real life?
The length of a UV ageing test and how many hours it is equivalent to are relative, depending on the equipment used, the test conditions and the properties of the material. Generally speaking, a UV ageing test of 1 hour is roughly equivalent to 27 days of natural climate exposure, as UV rays are part of solar radiation, and the intensity and frequency of UV rays will vary depending on the length of time and location of the natural climate exposure. Therefore, evaluations and comparisons need to be made on a case-by-case basis.
What do I need to pay attention to when using the UV aging tester?
- UV aging test chamber operation process, be sure to maintain an adequate water supply.
- The test phase should minimise the time to open the door.
- The sensing device inside the chamber, do not suffer strong impact.
- Non-specialised operators, shall not be operated at will.
- Please contact us when the equipment is not able to solve the problem by yourself.
- Ultraviolet aging test chamber for a long time after stopping the use, such as the need to use again, must carefully check the water supply, power supply and components, to determine that there is no error before starting the equipment.
- Due to ultraviolet radiation on the personnel (especially the eyes) has a strong hazard, so the operator should minimise exposure to ultraviolet radiation (contact time should be <1min). It is recommended that the operator with protective goggles and sheaths.
UV aging test chamber how to carry out maintenance work?
- The equipment is in a non-working situation, should keep it dry, will run after the discharge of water, dry studio and box.
- After use, the plastic cover to avoid dust intrusion. If there is dust, it should be removed.
Why is it necessary to use UV aging test chamber?
- UV-A, UV-B and UV-C and other different wavelengths of ultraviolet light can more realistically simulate the aging of the material in the outdoor exposure environment, speed up the aging process of the samples, and greatly shorten the test cycle.
- Ultraviolet weathering tester can carry out a large number of aging tests in a short period of time, accelerating the aging process of the material, and can more quickly assess the weathering performance and life of the material.
- UV aging test chamber temperature and humidity system can be set according to the needs of different temperature and humidity conditions. At the same time, you can also adjust the intensity and time of UV irradiation to meet the test requirements of different materials.
- Ultraviolet aging tester records the parameters of the material in the aging process, such as temperature, humidity, UV irradiation intensity and so on. These data can be used to analyze and assess the aging performance of the material and provide a scientific basis.
- Through the use of UV aging tester, can be obtained in a shorter period of time the aging performance data of the material, thus reducing the time and cost of the actual exposure test.
