Realistic Simulation of

Environmental Conditions:

The chamber replicates real-world exposure to UV radiation, moisture (dew and rain), high temperatures, and humidity. This allows for accelerated testing of how products and materials behave under these conditions over extended periods, simulating years of outdoor exposure in just a few weeks.

Programmable Test Parameters:

The programmable LCD touch display controller allows for easy customization of test parameters, including temperature, humidity, water spray, and irradiance levels. Operators can set up the tests to simulate a wide range of real-world conditions to best match specific product requirements.

Irradiance Control and Measurement:

Equipped with a UV irradiance measurement and control device (optional), the chamber ensures stable irradiance at 0.76W/m²/340nm or other user-defined levels, maintaining consistency throughout the test cycle. This precise control is crucial for evaluating material performance accurately.

Uniform Sample Exposure:

The chamber accommodates up to 18 standard panels (150x70mm). The samples are placed on a rotating drum, ensuring uniform exposure to the UV lamps and guaranteeing consistent irradiance across all test specimens. This enhances the repeatability and comparability of results.

Variety of UV Lamp Options (UVA and UVB):

The chamber is equipped with UV lamps (UVA and UVB), allowing the simulation of different wavelengths of sunlight.

UVA lamps simulate natural sunlight in the short-wave range, providing a realistic representation of sun exposure.

UVB lamps simulate more extreme conditions, suitable for testing materials exposed to intense sunlight over long periods, like automotive parts or materials for outdoor use in harsh climates.

Enhanced Durability and Long Life of Lamps:

The chamber is designed to extend the service life of the UV lamps. It automatically monitors blackboard temperature and water tank temperature to ensure that the lamps operate efficiently, preventing damage and ensuring consistent performance over extended periods of testing.

Water Spray and Condensing Humidity:

The chamber can simulate the effects of dew condensation and rain through water spray, which is essential for testing materials' resistance to moisture and UV-induced degradation. This feature adds realism to the simulation of outdoor exposure.

Versatile and User-Friendly Operation:

The touch-control interface and programmable settings offer flexibility and ease of use, making it simple to set up tests and monitor real-time conditions throughout the testing process.

Conclusion:

The ISO 4892-3 Accelerated UV Weathering Test Chamber is an essential tool for any industry involved in the production of materials or components exposed to outdoor conditions. Its ability to simulate the effects of UV radiation, heat, humidity, and moisture allows for comprehensive aging tests that provide valuable insights into the long-term durability and performance of products. By accelerating the aging process, manufacturers can ensure better product reliability, optimize design, and meet industry standards for weather resistance.
