Accelerated xenon chamber, UV chamber and thermal chamber aging tests allow you to simulate the climatic conditions to which products can be subjected and to assess the degradation of material properties, operating conditions and wear. The equipment, such as those recently acquired by SCiTec, is able to accurately control the test variables and thus generate results of high metrological reliability.
Different conditions, different tests
There are several equipments to simulate the various weathering situations:
The climatic chamber allows temperature and relative humidity parameters to be controlled and recorded throughout the test. The systems available at SCiTec allow testing with temperatures ranging from -70 ºC to 180 ºC. They are chambers of various sizes and ranges of operating temperature and humidity.
The greenhouses are used in tests with temperature above room temperature, in these cases it is also possible to do the humidity control during the test. From the rise of the temperature it is possible to accelerate the degradation of the material, or the product, and with this occurs an accelerated aging. As an example, we can mention the accelerated aging of packaging.
Thermal Aging – UV
The UV thermal aging equipment allows simulating the solar ultraviolet for the shortwave region. It is widely used for testing in plastics and coatings. Thus, it is possible to observe effects such as loss of color or brightness, clouding, opacity, loss of adhesion and resistance, appearance of cracks, blisters, among others.
Thermal Aging – ARC Xenon
Xenon chamber aging is performed by means of ultraviolet aging instruments equipped with a xenon arc lamp. This is the accelerated aging assay that best simulates natural aging because it simulates the full spectrum of sunlight, including UV, visible and infrared.
Climate and aging tests can be carried out according to specific standards or according to the customer’s needs.
These tests evaluate the loss of resistance of the materials in the face of weathering, that is, they simulate wear to reproduce the damage caused by sunlight, rain and dew, which would occur over months or years.
