What is a xenon lamp weathering testing machine?
The xenon lamp weathering testing machine is an experimental equipment that simulates natural lighting, temperature, humidity and other environmental conditions. It is mainly used to test the weathering performance of materials (such as plastics, coatings, textiles, etc.) under long-term exposure to sunlight, rain and other natural environments. By simulating the solar spectrum with a xenon lamp, combined with a temperature and humidity control system, the material aging process can be accelerated and help companies and research institutions quickly evaluate the durability of products.

Core functions of xenon lamp weathering testing machine
1.Spectral simulation: Xenon lamp can cover ultraviolet, visible light and infrared spectrum, close to real sunlight.
2.Temperature and humidity control: Usually the temperature range is -40℃~100℃, and the humidity controllable range is 20%~95%RH.
3.sprinkler system: Simulate rain environment and test the water resistance of materials.
4.data logging: Real-time monitoring and recording of irradiance, temperature, humidity and other parameters.
Examples of typical test standards
| Standard name | Scope of application |
|---|---|
| ISO 4892-2 | Xenon lamp exposure test method for plastic materials |
| ASTM G155 | Non-metallic materials weather resistance test |
| GB/T 1865 | Artificial weathering test of paints and varnishes |
Industry application cases
1.Automotive industry: Test exterior parts (such as bumpers, lights) for fading and cracking.
2.building materials: Evaluate the long-term performance of curtain wall glass and waterproofing membranes.
3.electronic products: Verify the weather resistance of outdoor display screens and solar panel backsheets.
Precautions when purchasing
•Spectral match: Select a spectral filter that complies with CIE No.85 standards.
•Control system accuracy: Temperature and humidity fluctuation should be ≤±1℃/±2%RH.
•After-sales service: The life of xenon lamp is usually 1000-2000 hours, and the replacement cost needs to be considered.
With the growing demand for new material research and development, xenon lamp weathering testing machines have become an important tool in the field of quality inspection. In the future, intelligent testing systems combined with big data analysis may further promote the development of this technology.
