The xenon lamp weathering resistance test box passes the accelerated test of simulating the long-term exposure of natural sunlight to obtain the result of the weather resistance of the material. In order to obtain the complete characteristics of the entire exposure process, it is necessary to determine the change of the test sample in multiple exposure stages. This method can also be used to estimate the amount of radiation required when the material produces a certain change.
The xenon lamp weathering test box can be used to determine whether the quality of different batches of materials is the same as the known control sample. In advance, select an appropriate exposure time according to the weather resistance of the material and evaluate the change of the test sample at this exposure time. When exposed for a specified period of time, the reproducibility of the exposure results must be determined for the material being tested. It is also possible to determine the exposure time required for the test sample to produce a certain change. Xenon lamp weather resistance test chamber is used to specify product performance indicators. Evaluate the product performance changes according to the prescribed test method to determine whether the product is qualified.
The factors causing the difference in product correlation are: a. Contains ultraviolet radiation with a shorter wavelength than natural sunlight exposure; b. The relative energy distribution of the radiation spectrum differs greatly from sunlight; c. The irradiance is very high; d. The test sample has a high temperature , Especially for materials that can quickly emit changes when heated; e. Use impure water.
