The xenon lamp weathering test chamber can simulate material changes. It does this by exposing them to sunlight, rain, and dew in various environments.
The xenon lamp weathering test chamber uses a xenon lamp to simulate sunlight. It uses condensed moisture to simulate rain and dew. The test material is exposed to a cycle of alternating light and moisture at a set temperature. Such testing can reproduce in days or weeks the hazards that can occur outdoors over months or even years, thus helping to select new materials, improve existing ones, and evaluate the effects of formulation changes on product durability.
The main features of the xenon lamp weathering test chamber include:
● The use of full-spectrum xenon light emitting tubes, capable of simulating the full sunlight spectrum.
Provides a wide selection of filtration systems to suit different testing needs.
● With rain shower function, can simulate the effect of rain on the material.
The relative humidity can be controlled to simulate different humidity environments.
●Test chamber air temperature control system to ensure temperature control of the testing environment.
● Irregularly shaped sample holder, adapting to different shapes and sizes of samples.
●Xenon arc lamps are economical and have a long service life.
What are the specific requirements for the environment in testing with a xenon lamp weathering test chamber?
1. Simulate the light intensity under different environmental conditions:
A xenon lamp weathering test chamber must simulate full sunlight. It should include ultraviolet, visible, and infrared light. This will ensure the test samples receive light similar to the natural environment.
2. With a precise temperature control system:
It can simulate temperature changes under different climatic conditions. The temperature range is room temperature to 80°C. For other requirements, please consult us for customization.
3. Can simulate the humidity conditions in the actual environment:
The xenon lamp weathering test chamber can control humidity between 30% and 95%. This function can accelerate the material's aging.
4. With water spray system:
This feature can simulate natural conditions, like rainfall or dew, at varied frequencies and intensities.
5. Sample racks:
Sample racks are well designed to ensure that samples are evenly exposed to light and environmental factors.
Also, our sample holders are easy to install and replace. This ensures that the samples are not stressed or damaged during testing.
5. Testing time:
The testing time is based on your material's expected life and the actual usage environment. We can ensure the accuracy and reliability of the results while the equipment is being tested.
6. Stability of testing conditions:
During testing, ensure that light, temperature, and humidity are stable.
7. Safety protection:
Our xenon lamp weathering test chamber has alarm protections for your safety. These include over-temperature and heating overload alarms.
8.Evaluation of test results:
At the end of the test, you can evaluate changes in appearance, performance, and corrosion of the sample. Then, compare it with the unexposed material. This will determine the material's weather resistance and service life.
How much does the xenon lamp tester need to be adjusted to simulate light intensity under different climates?
In general, it needs to be adjusted according to the specific test criteria and material properties.
The earth's surface irradiance is 1120 W/m², per CIE 85. It is influenced by the solar constant and the atmosphere's attenuation and scattering.
In section 5.8 of the standard, “Test equipment”, it is stated that the irradiance should be 1120 W/m² (1±10%).
To simulate direct outdoor sunlight, it is recommended to use a 340nm point control with an irradiance setting of 0.60 W/m² @ 340 nm.
How many degrees of temperature do I usually need to set for the xenon lamp weathering test chamber when simulating aging tests under high-temperature conditions?
In general, the temperature is set according to different test standards and material properties.
According to IEC 60068-2-5, the temperature can be set to 40 °C during the light phase and 25°C during the dark phase.
These temperature settings refer to specific tests, like A, B, and C. They have different light and dark cycles and temperature requirements.
For example, Program A has 8 hours of light and 16 hours of darkness. Program B has 20 hours of light and 4 hours of darkness. These programs are designed to simulate the aging process of materials under different environmental conditions.
