The xenon arc test chamber uses a xenon arc lamp as a light source. The weathering and accelerated aging tests were studied by simulating the real environment conditions closely.
We use different spectra, temperatures, and humidity for controlled product degradation studies (weathering). This method can be used to evaluate the weather resistance of test materials or samples.
In fact, weather resistance testing is an important way to optimize the composition of your products during research and production. At the same time, it is also an important part of your product quality inspection. What’s more, coatings, plastics, aluminum-plastic panels, automotive safety glass, and other industries need to do this weather resistance test.
Linkotest designs and manufactures environment test chambers including temperature humidity chambers, walk-in test chambers, thermal shock test chambers, fast change rate test chambers, agree chambers, xenon arc test chambers, uv test chamber, accelerated aging test chambers, rain & spray test chamber, salt spray test chamber, compound salt spray test chamber, laboratory oven, and other products to meet your different environmental test needs.
What we can tell you is that xenon arc test chambers are used to best simulate the full spectrum of sunlight, as well as the destructive waves present in different environments. Provide appropriate environmental simulation and accelerated testing for scientific research, product development, and quality control.
Furthermore, xenon weathering tests can be used for durability tests after the selection of new materials, as well as to improve the existing evaluation of material changes or changes in material composition. The test chamber best simulates how your material is exposed to sunlight under different environmental conditions.

The followings are the feathers and advantages of the xenon arc test chamber.
- Broad spectral range.
- Available in flat and round drum configurations.
- Automatic monitoring and control of internal conditions.
- S1 high-purity quartz transparent film, gold-plated silicon corrosion-resistant mirror, and high-temperature linear photosensitive element ensure that the measurement accuracy is not affected by high and low-temperature changes.
It provides a more realistic degradation study than traditional UV chamber testing. A wider spectral range and optional ultra-wide spectrum produce more realistic results.
Moreover, the xenon arc test chamber has a reasonable price, complete functions, and a large sample capacity. In addition, it provides precise control of key test parameters. Includes spectrum, irradiance, relative humidity, room temperature, and black standard temperature.
Likewise, xenon arc test chambers can be used for the selection of new materials. Because of the improvement of existing materials or the evaluation of product formulation changes that affect product durability. Therefore, it is an ideal instrument for fully accelerated light stability and weathering tests and can be used to quickly test light stability.
Xenon Test Chamber

Xenon Arc test chambers from our company have been used in various laboratories for many years for quality testing and research experiments. These Xenon Arc Weathering Instruments can help you determine the possible damage to your product when exposed to full-spectrum sunlight and rain.
If you use a set of procedures to alternate test sample cycles. And put it in a certain temperature, light, and humidity. You can then replicate in a matter of days or weeks the damage caused by months or years of outdoor weathering.
Some of the common methods our chambers can be used for are as follows:
- ASTM G155: Standard Practice for Operating Xenon Arc Lamp Equipment to Expose Nonmetallic Materials.
- ASTM 04459: Standard Practice for Xenon Arc Exposure of Plastics for Indoor Applications.
- ISO 4892-1 Plastics – Method of exposure to laboratory light sources.
- ISO 16474-2 Paints and varnishes – Methods of exposure to laboratory light sources – Part 2
Let’s compare the xenon test chamber and UV test chamber.
1) UV lamp irradiation test method
- UV fluorescent lamps illuminate UV lamps to simulate the damaging effects of sunlight on durable materials.
- It is electrically different from the aforementioned xenon arc lamps, fluorescent UV lamps, and ordinary fluorescent lamps, illuminating cold light but producing more ultraviolet light than visible or infrared light.
- For different exposure applications, different types of lamps with different spectra are available.
- The uva-340 lamps in the main short wavelength UV spectral range simulate sunlight well.
- The spectral power distribution (SPD) of UVA lamps is similar to the 360nm spectrum in the solar spectrum.
- UVB lamps are also used for accelerated artificial aging tests.
- It destroys materials faster than UVA lamps, but its shorter wavelength energy output than 360 nm causes deviations from actual test results.
2) Xenon arc radiation test method
- The xenon arc radiation test is considered to best simulate the full solar spectrum because it produces ultraviolet, visible, and infrared light. Because of this, it is considered the most widely used method at home and abroad.
- This method is described in detail in GB/T1865-1997 (equivalent to IS0113411:1994).
- But this method also has its limitations, namely the stability of the xenon arc light source and the complexity of the experimental system.
- Xenon arc light sources must be filtered to reduce unwanted radiation.
- There are many types of filter glass for different irradiance distributions.
- The type of glass chosen depends on the type of material being tested and its end use.
- Replacing the filter glass can change the type of short-wave UV light through which materials can be damaged.
- The commonly used filtering methods are sunlight, window glass, and extended ultraviolet rays (methods 1 and 2 mentioned in GB/t1865-1997 correspond to the first two).
