ASTM D7869使用暴露于运输涂料的增强光和水进行氙弧曝光试验的标准实施规程
标准名称
ASTM D7869 Standard Practice for Xenon Arc Exposure Test with Enhanced Light and Water Exposure for Transportation Coatings
ASTM D7869使用暴露于运输涂料的增强光和水进行氙弧曝光试验的标准实施规程
适用范围
Scope:
This practice specifies the operating procedures for a controlled irradiance xenon arc light and water apparatus. The procedure uses one or more lamp(s) and optical filter(s) to produce irradiance similar to sunlight in the UV and visible range. It also simulates the water absorption and stress cycles experienced by automotive exterior coatings under natural weathering conditions. This practice has also been found applicable to coatings on other transportation vehicles, such as aircraft, trucks and rail cars
