    ASTM G154 UV UVA340 Lamp Weathering Aging Test Chamber Programmable


    Programmable ASTM G154 UVA 340 Weathering Aging Test Chamber


    Product Description

    This UV weathering accelerated ageing test chamber adopts UV light generated by the fluorescent ultraviolet lamps to simulate sunlight, and uses condensation moisture to simulate rain and dew. The sample is tested in a cycle of alternating light and moisture at a certain temperature, the hazards that occurred outdoors for months to years can be reproduced by UV within several days or weeks, so as to simulate the hazards caused on the sample by sunlight, rain, and dew, the hazard types include: discoloration, discoloration, loss of light, chalking, cracking, turbidity, bubbles, brittleness, reduced strength and oxidation. The test data can help user choose new materials and evaluate how changes in the formulation affect new product substitution.


    The UV weathering accelerated ageing test chamber conforms to standards:

    GB/T 14522-93 “Accelerated Weathering Test Method for Plastics, Coatings, Rubber Materials Used for Machinery Industrial Products”

    ASTM G154 “Standard Practice for Operating Fluorescent Ultraviolet (UV) Lamp Apparatus for Exposure of Nonmetallic Materials1”

    ISO 4892-1-2016 “Plastics-Methods of exposure to laboratory light sources-Part 1: General guidance”

    ISO 11507 -2007 “Paints and varnishes - Exposure of coatings to artificial weathering - Exposure to fluorescent UV lamps and water”

    ASTMD 4329-2005 “Standard Practice for Fluorescent UV Exposure of Plastic”
