BS EN 14187-8 discusses the process and test methods for determination of artificial weathering by UV-irradiation. BS EN 14187-8 describes a test method for evaluating the resistance of cold applied joint sealants to the action of UV-light by determination of the change of physical properties after irradiation by artificial UV-light.
BS EN 14187-8 on determination of the artificial weathering by UV-irradiation is useful for:
Exposure to sunlight and some artificial lights can have adverse effects on the useful life of sealants. UV - irradiation can break down the chemical bond in a polymer.
BS EN 14187-8 specifies a test method for the determination of the artificial weathering by UV-irradiation which is used to measure future possibilities of materials’ durability under certain environmental conditions. BS EN 14187-8 helps to measures how a product changes during exposure which helps to make better and more durable products, no matter what the conditions.
