ENVIRONMENTAL TESTS
Solar radiation test is made to determine the thermal effects or photochemical deterioration effects created on the tested material by direct exposure to solar radiation. For this test special rooms or chambers containing solar lamp groups where temperature, airflow and radiation are kept under control. This method has two aims;
1. To measure the effect of temperature and solar radiation on the material.
2. To define solar radiation effects.
This method should be used to evaluate the material which would possibly be exposed to sunray throughout its life cycle in hot climates. Heating or actinic effects can be observed. This method (solar spectrum and energy levels at sea level) is valuable for evaluating the effects of direct solar exposure. Procedure I is useful to determine temperature increase on the material (in the environment) due to solar load. Procedure II is used to simulate ultraviolet effect of solar radiation at different locations and heights using different radiation sources for the proper comparison of measurements of natural solar radiation conditions.
