UV radiation The natural weathering of materials exposed to the above conditions may take many years, which is impractical for expeditiously testing and developing products. As such, weathering chambers provide a space where artificial weather conditions can be created in an accelerated and controlled manner.
offers 361 artificial climate chamber products. About 47% of these are testing equipment, 1% are drying oven. A wide variety of artificial climate chamber options are available to you, such as auto testing machine, universal testing machine, and process testing machine.
Weather testing of polymers is the controlled polymer degradation and polymer coating degradation under lab or natural conditions. Just like erosion of rocks, natural phenomena can cause degradation in polymer systems. The elements of most concern to polymers are ultraviolet radiation, moisture and humidity, high temperatures and temperature fluctuations. Polymers are used in everyday life, so it is …
samples were exposed in a laboratory weathering chamber using two irradiance levels and two mois-ture cycles. The artificial and naturally weathered samples were then compared. With the exception of mildew growth, the laboratory exposures with moisture degraded the …
controlled artificial light sources in the laboratory, whereas natural weathering is performed in large outdoor fields with real sunlight but where all the exposure parameters are not controlled. See Table 1 for a comparison of the outdoor tests and accelerated tests.

Artificial Weathering - an overview ScienceDirect Topics
The artificial weathering of biocomposites can be carried out in a weathering chamber, where the test to investigate their life service durability under UV radiation is usually carried out in a particular apparatus that exposes the materials to the UV light for hundreds of hours, depending on the standards and the final purpose of the test [142,143].

UV light in sunlight and diffuse sky radiation is especially important. It can cause alterations in the surface of materials, which – accelerated by other climate factors, such as temperature and humidity – lead to the typical symptoms of aging.
Xenon lamp aging testing machine is a comprehensive climate testing machine, in addition to climatic aging test, the lightfastness of materials can be carried out to test, polymer materials exposed at simulated sunlight.
Integrating Sphere-based Weathering Device. In the artificial ultraviolet (UV) weathering of materials, a need exists for weathering devices that can uniformly illuminate test specimens with a high level of irradiance, and additionally provide capabilities such as mechanical loading. Developed under the auspices of the NIST Coatings Service Life...
UV aging chambers use fluorescent ultraviolet lamp as light source to simulate UV radiation and condensation in natural sunlight, and to carry out accelerated weather resistance test in order to obtain the result of weather resistance of the material.
Overview +. The Atlas SUNTEST XXL+ is a large xenon lamp weathering and lightfastness test chamber meeting various ISO, ASTM, and ICH industry standards. Its horizontal 3000 cm2 exposure area is best-in-class for 3-D specimen testing. The SUNTEST XXL+ is used to check for property changes of materials and products caused by sunlight,...

Annex C gives the calculation method for the determination of the radiation and exposure time to be used for artificial weathering. 2 Principle Test specimens, being a cured assembled “system” of a liquid applied roof waterproofing kit, are exposed in a Xenon arc or fluorescent UV artificial ...
Correlation between accelerated weathering duration and ...
A. Correlation between outdoor and artificial weathering devices is very material dependent. Factors that must be considered are light (both quantity and quality), moisture cycles, and temperature. I don't know if 3000 hours is close to 125 months, but that sounds a bit unrealistic.
These include artificial UV weathering of materials using a QSUN xenon arc weathering chamber (ASTM G155) and/or QUV fluorescent/condensation weathering apparatus (ASTM G154). Other artificial ageing methods can be developed to suit the material.

(UV) chambers are widely used to obtain weathering data for a wide range of commer-cial polymer products in-cluding coatings, textiles, elastomers, plastics, and polymeric composites. Although numerous im-provements have been made in the design of UV chambers over the last 80 years, the reproduc-ibility of the exposure results from these cham-bers has remained elusive.
These climate altering test chambers allow you to test weathering elements, such as salt spray and corrosion. Learn more about our various series, including Weiss Technik North America SC Walk-In, Solar Climatic Series, BSB Test Cabinet, and more.
