ISO 4582 is a standard that specifies methods for determining color changes and changes in physical properties of plastics after exposure to different light sources, including natural weathering, laboratory light sources and exposure under glass.
The standard covers several aspects of exposure testing, including the selection and preparation of test samples, the control of exposure parameters such as irradiance, temperature and relative humidity, and the evaluation of test results, such as the color, gloss and physical properties of the tested plastics The change.
ISO 4582 specifies three different exposure procedures: exposure to sunlight under glass, exposure to natural weathering, and exposure to laboratory light sources. The choice of exposure procedure depends on the intended application of the plastic being tested.
The standard is widely used in various industries, including the automotive, building and construction, and aerospace industries, to evaluate the durability and weatherability of plastics. By subjecting test samples to simulated weathering conditions, the standard helps evaluate the long-term performance of plastics and provides valuable information for product development and quality control.
