The test using xenon as a source of light is considered to be the most effective method for estimating the weathering of polymers for quality control. Majorly there are three main factors which causes the polymer weathering which includes solar radiations, changing temperature, and moisture. Among which a xenon test delivers major resemblance for the UV radiations. Therefore, utilization of a Xenon Test Chamber is a common sight in plastic industries.

The natural light coming from sun is composed of three main wavelength ranges which includes, Ultraviolet, visible and infrared rays. It is said that the shorter the wavelength of the rays are, more intense will be its effect on the polymer material. Thus, generating a weathering of polymer on long exposures of sunlight. The Xenon arc lamp equipped in the chamber simulates the sunlight efficiently making it the best option for testing the exposure of natural sunlight.

The accelerated weathering test is an important parameter for polymer manufacturers to assure that the material meet their expected performance and validity. The polymer material and constructed products often has applications which require their presence out in direct heat of sunlight and with prolong exposure of sunlight, plastic can generate crack and even burst to fail. Therefore, the xenon test is conducted for polymer quality control.

 

The chamber is installed with 1.8KW iXenon lamp for imitating natural sunlight. Daylight filter or Windows Glass filter is there to filter the light prior falling on the sample. The lamp life expectancy range from 1,500 to 2,000 hours. Can test a wide range of products with 1,000 cm2 Exposure area. Around 9 pieces of specimen can be kept in one go for a single test cycle. Along with xenon lamp, fluorescent lamp is also aligned in the chamber.
