ASTM G154 (Standard Practice for Operating Fluorescent Light Apparatus for UV Exposure of Non-Metallic Materials)

ASTM G154 is a standard that guides how to use fluorescent UV light machines to test the durability of non-metallic materials, like plastics or paints. It specifies procedures for exposing materials to UV light under controlled conditions to simulate sunlight, helping predict how they will perform over time. This testing is essential for manufacturers to assess weathering resistance, ensuring products like outdoor plastics or coatings withstand UV exposure without degrading prematurely. Overall, ASTM G154 ensures consistent, reliable testing of materials’ UV durability across different laboratories and industries.
