Climate simulation and accelerated aging tests

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 SCiTec’s equipments are able to accurately control the test variables and thus generate results of high metrological reliability.

There are several equipments to simulate the various weathering situations:

Climate chamber

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. 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, opacity, loss of adhesion and resistance, cracks, among other failures.

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 test that simulates natural aging with 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 weathering of the materials, simulating conditions to mimic the damage caused by sunlight, rain and dew, which would occur over months or years.
